The version of Firefox ESR installed on the remote Windows host is prior to 68.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-33 advisory.

  - Mozilla developers and community members Bob Clary, Jason Kratzer, Aaron Klotz, Iain Ireland, Tyson Smith,     Christian Holler, Steve Fink, Honza Bambas, Byron Campen, and Cristian Brindusan reported memory safety     bugs present in Firefox 69 and Firefox ESR 68.1. Some of these bugs showed evidence of memory corruption     and we presume that with enough effort some of these could be exploited to run arbitrary code.
    (CVE-2019-11764)

  - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to     document parsing too early. A subsequent call to <code>XMLGetCurrentLineNumber</code> or     <code>XMLGetCurrentColumnNumber</code> then resulted in a heap-based buffer over-read. (CVE-2019-15903)

  - When following the value's prototype chain, it was possible to retain a reference to a locale, delete it,     and subsequently reference it. This resulted in a use-after-free and a potentially exploitable crash.
    (CVE-2019-11757)

  - Mozilla community member Philipp reported a memory safety bug present in Firefox 68 when 360 Total     Security was installed. This bug showed evidence of memory corruption in the accessibility engine and we     presume that with enough effort that it could be exploited to run arbitrary code. (CVE-2019-11758)

  - An attacker could have caused 4 bytes of HMAC output to be written past the end of a buffer stored on the     stack. This could be used by an attacker to execute arbitrary code or more likely lead to a crash.
    (CVE-2019-11759)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version MAIN 4.05, has firefox packages installed that are affected by multiple vulnerabilities:

  - Insufficient vetting of parameters passed with the     Prompt:Open IPC message between child and parent     processes can result in the non-sandboxed parent process     opening web content chosen by a compromised child     process. When combined with additional vulnerabilities     this could result in executing arbitrary code on the     user's computer. This vulnerability affects Firefox ESR     < 60.7.2, Firefox < 67.0.4, and Thunderbird < 60.7.2.
    (CVE-2019-11708)

  - A type confusion vulnerability can occur when     manipulating JavaScript objects due to issues in     Array.pop. This can allow for an exploitable crash. We     are aware of targeted attacks in the wild abusing this     flaw. This vulnerability affects Firefox ESR < 60.7.1,     Firefox < 67.0.3, and Thunderbird < 60.7.2.
    (CVE-2019-11707)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 67 and Firefox ESR 60.7.
    Some of these bugs showed evidence of memory corruption     and we presume that with enough effort that some of     these could be exploited to run arbitrary code. This     vulnerability affects Firefox ESR < 60.8, Firefox < 68,     and Thunderbird < 60.8. (CVE-2019-11709)

  - When an inner window is reused, it does not consider the     use of document.domain for cross-origin protections. If     pages on different subdomains ever cooperatively use     document.domain, then either page can abuse this to     inject script into arbitrary pages on the other     subdomain, even those that did not use document.domain     to relax their origin security. This vulnerability     affects Firefox ESR < 60.8, Firefox < 68, and     Thunderbird < 60.8. (CVE-2019-11711)

  - POST requests made by NPAPI plugins, such as Flash, that     receive a status 308 redirect response can bypass CORS     requirements. This can allow an attacker to perform     Cross-Site Request Forgery (CSRF) attacks. This     vulnerability affects Firefox ESR < 60.8, Firefox < 68,     and Thunderbird < 60.8. (CVE-2019-11712)

  - A use-after-free vulnerability can occur in HTTP/2 when     a cached HTTP/2 stream is closed while still in use,     resulting in a potentially exploitable crash. This     vulnerability affects Firefox ESR < 60.8, Firefox < 68,     and Thunderbird < 60.8. (CVE-2019-11713)

  - Due to an error while parsing page content, it is     possible for properly sanitized user input to be     misinterpreted and lead to XSS hazards on web sites in     certain circumstances. This vulnerability affects     Firefox ESR < 60.8, Firefox < 68, and Thunderbird <     60.8. (CVE-2019-11715)

  - A vulnerability exists where the caret (^) character     is improperly escaped constructing some URIs due to it     being used as a separator, allowing for possible     spoofing of origin attributes. This vulnerability     affects Firefox ESR < 60.8, Firefox < 68, and     Thunderbird < 60.8. (CVE-2019-11717)

  - A vulnerability exists where if a user opens a locally     saved HTML file, this file can use file: URIs to access     other files in the same directory or sub-directories if     the names are known or guessed. The Fetch API can then     be used to read the contents of any files stored in     these directories and they may uploaded to a server. It     was demonstrated that in combination with a popular     Android messaging app, if a malicious HTML attachment is     sent to a user and they opened that attachment in     Firefox, due to that app's predictable pattern for     locally-saved file names, it is possible to read     attachments the victim received from other     correspondents. This vulnerability affects Firefox ESR <     60.8, Firefox < 68, and Thunderbird < 60.8.
    (CVE-2019-11730)

  - As part of a winning Pwn2Own entry, a researcher     demonstrated a sandbox escape by installing a malicious     language pack and then opening a browser feature that     used the compromised translation. This vulnerability     affects Firefox ESR < 60.8, Firefox < 68, and     Thunderbird < 60.8. (CVE-2019-9811)

  - When a master password is set, it is required to be     entered again before stored passwords can be accessed in     the 'Saved Logins' dialog. It was found that locally     stored passwords can be copied to the clipboard thorough     the 'copy password' context menu item without re-     entering the master password if the master password had     been previously entered in the same session, allowing     for potential theft of stored passwords. This     vulnerability affects Firefox < 68.0.2 and Firefox ESR <     68.0.2. (CVE-2019-11733)

  - Given a compromised sandboxed content process due to a     separate vulnerability, it is possible to escape that     sandbox by loading accounts.firefox.com in that process     and forcing a log-in to a malicious Firefox Sync     account. Preference settings that disable the sandbox     are then synchronized to the local machine and the     compromised browser would restart without the sandbox if     a crash is triggered. This vulnerability affects Firefox     ESR < 60.9, Firefox ESR < 68.1, and Firefox < 69.
    (CVE-2019-9812)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 68, Firefox ESR 68, and     Firefox 60.8. Some of these bugs showed evidence of     memory corruption and we presume that with enough effort     that some of these could be exploited to run arbitrary     code. This vulnerability affects Firefox < 69,     Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR <     60.9, and Firefox ESR < 68.1. (CVE-2019-11740)

  - A same-origin policy violation occurs allowing the theft     of cross-origin images through a combination of SVG     filters and a <canvas> element due to an error in     how same-origin policy is applied to cached image     content. The resulting same-origin policy violation     could allow for data theft. This vulnerability affects     Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9,     Firefox ESR < 60.9, and Firefox ESR < 68.1.
    (CVE-2019-11742)

  - Navigation events were not fully adhering to the W3C's     Navigation-Timing Level 2 draft specification in some     instances for the unload event, which restricts access     to detailed timing attributes to only be same-origin.
    This resulted in potential cross-origin information     exposure of history through timing side-channel attacks.
    This vulnerability affects Firefox < 69, Thunderbird <     68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and     Firefox ESR < 68.1. (CVE-2019-11743)

  - Some HTML elements, such as <title> and     <textarea>, can contain literal angle brackets     without treating them as markup. It is possible to pass     a literal closing tag to .innerHTML on these elements,     and subsequent content after that will be parsed as if     it were outside the tag. This can lead to XSS if a site     does not filter user input as strictly for these     elements as it does for other elements. This     vulnerability affects Firefox < 69, Thunderbird < 68.1,     Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR     < 68.1. (CVE-2019-11744)

  - A use-after-free vulnerability can occur while     manipulating video elements if the body is freed while     still in use. This results in a potentially exploitable     crash. This vulnerability affects Firefox < 69,     Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR <     60.9, and Firefox ESR < 68.1. (CVE-2019-11746)

  - It is possible to delete an IndexedDB key value and     subsequently try to extract it during conversion. This     results in a use-after-free and a potentially     exploitable crash. This vulnerability affects Firefox <     69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR     < 60.9, and Firefox ESR < 68.1. (CVE-2019-11752)

  - When following the value's prototype chain, it was     possible to retain a reference to a locale, delete it,     and subsequently reference it. This resulted in a use-     after-free and a potentially exploitable crash. This     vulnerability affects Firefox < 70, Thunderbird < 68.2,     and Firefox ESR < 68.2. (CVE-2019-11757)

  - Mozilla community member Philipp reported a memory     safety bug present in Firefox 68 when 360 Total Security     was installed. This bug showed evidence of memory     corruption in the accessibility engine and we presume     that with enough effort that it could be exploited to     run arbitrary code. This vulnerability affects Firefox <     69, Thunderbird < 68.2, and Firefox ESR < 68.2.
    (CVE-2019-11758)

  - If two same-origin documents set document.domain     differently to become cross-origin, it was possible for     them to call arbitrary DOM methods/getters/setters on     the now-cross-origin window. This vulnerability affects     Firefox < 70, Thunderbird < 68.2, and Firefox ESR <     68.2. (CVE-2019-11762)

  - Failure to correctly handle null bytes when processing     HTML entities resulted in Firefox incorrectly parsing     these entities. This could have led to HTML comment text     being treated as HTML which could have led to XSS in a     web application under certain conditions. It could have     also led to HTML entities being masked from filters -     enabling the use of entities to mask the actual     characters of interest from filters. This vulnerability     affects Firefox < 70, Thunderbird < 68.2, and Firefox     ESR < 68.2. (CVE-2019-11763)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 69 and Firefox ESR 68.1.
    Some of these bugs showed evidence of memory corruption     and we presume that with enough effort some of these     could be exploited to run arbitrary code. This     vulnerability affects Firefox < 70, Thunderbird < 68.2,     and Firefox ESR < 68.2. (CVE-2019-11764)

  - An attacker could have caused 4 bytes of HMAC output to     be written past the end of a buffer stored on the stack.
    This could be used by an attacker to execute arbitrary     code or more likely lead to a crash. This vulnerability     affects Firefox < 70, Thunderbird < 68.2, and Firefox     ESR < 68.2. (CVE-2019-11759)

  - A fixed-size stack buffer could overflow in nrappkit     when doing WebRTC signaling. This resulted in a     potentially exploitable crash in some instances. This     vulnerability affects Firefox < 70, Thunderbird < 68.2,     and Firefox ESR < 68.2. (CVE-2019-11760)

  - By using a form with a data URI it was possible to gain     access to the privileged JSONView object that had been     cloned into content. Impact from exposing this object     appears to be minimal, however it was a bypass of     existing defense in depth mechanisms. This vulnerability     affects Firefox < 70, Thunderbird < 68.2, and Firefox     ESR < 68.2. (CVE-2019-11761)

  - Under certain conditions, when checking the Resist     Fingerprinting preference during device orientation     checks, a race condition could have caused a use-after-     free and a potentially exploitable crash. This     vulnerability affects Thunderbird < 68.3, Firefox ESR <     68.3, and Firefox < 71. (CVE-2019-17010)

  - Under certain conditions, when retrieving a document     from a DocShell in the antitracking code, a race     condition could cause a use-after-free condition and a     potentially exploitable crash. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17011)

  - Mozilla developers reported memory safety bugs present     in Firefox 70 and Firefox ESR 68.2. Some of these bugs     showed evidence of memory corruption and we presume that     with enough effort some of these could have been     exploited to run arbitrary code. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17012)

  - When using nested workers, a use-after-free could occur     during worker destruction. This resulted in a     potentially exploitable crash. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17008)

  - The plain text serializer used a fixed-size array for     the number of  elements it could process; however it     was possible to overflow the static-sized array leading     to memory corruption and a potentially exploitable     crash. This vulnerability affects Thunderbird < 68.3,     Firefox ESR < 68.3, and Firefox < 71. (CVE-2019-17005)

This vulnerability affects Firefox <     69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR     < 60.9, and Firefox ESR < 68.1. (CVE-2019-11752)

  - A flaw in Thunderbird's implementation of iCal causes a     stack buffer overflow in icalrecur_add_bydayrules when     processing certain email messages, resulting in a     potentially exploitable crash. This vulnerability     affects Thunderbird < 60.7.1. (CVE-2019-11705)

  - A flaw in Thunderbird's implementation of iCal causes a     type confusion in icaltimezone_get_vtimezone_properties     when processing certain email messages, resulting in a     crash. This vulnerability affects Thunderbird < 60.7.1.
    (CVE-2019-11706)

  - When following the value's prototype chain, it was     possible to retain a reference to a locale, delete it,     and subsequently reference it. This resulted in a use-     after-free and a potentially exploitable crash. This     vulnerability affects Firefox < 70, Thunderbird < 68.2,     and Firefox ESR < 68.2. (CVE-2019-11757)

  - Mozilla community member Philipp reported a memory     safety bug present in Firefox 68 when 360 Total Security     was installed. This bug showed evidence of memory     corruption in the accessibility engine and we presume     that with enough effort that it could be exploited to     run arbitrary code. This vulnerability affects Firefox <     69, Thunderbird < 68.2, and Firefox ESR < 68.2.
    (CVE-2019-11758)

  - If two same-origin documents set document.domain     differently to become cross-origin, it was possible for     them to call arbitrary DOM methods/getters/setters on     the now-cross-origin window. This vulnerability affects     Firefox < 70, Thunderbird < 68.2, and Firefox ESR <     68.2. (CVE-2019-11762)

  - Failure to correctly handle null bytes when processing     HTML entities resulted in Firefox incorrectly parsing     these entities. This could have led to HTML comment text     being treated as HTML which could have led to XSS in a     web application under certain conditions. It could have     also led to HTML entities being masked from filters -     enabling the use of entities to mask the actual     characters of interest from filters. This vulnerability     affects Firefox < 70, Thunderbird < 68.2, and Firefox     ESR < 68.2. (CVE-2019-11763)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 69 and Firefox ESR 68.1.
    Some of these bugs showed evidence of memory corruption     and we presume that with enough effort some of these     could be exploited to run arbitrary code. This     vulnerability affects Firefox < 70, Thunderbird < 68.2,     and Firefox ESR < 68.2. (CVE-2019-11764)

  - An attacker could have caused 4 bytes of HMAC output to     be written past the end of a buffer stored on the stack.
    This could be used by an attacker to execute arbitrary     code or more likely lead to a crash. This vulnerability     affects Firefox < 70, Thunderbird < 68.2, and Firefox     ESR < 68.2. (CVE-2019-11759)

  - A fixed-size stack buffer could overflow in nrappkit     when doing WebRTC signaling. This resulted in a     potentially exploitable crash in some instances. This     vulnerability affects Firefox < 70, Thunderbird < 68.2,     and Firefox ESR < 68.2. (CVE-2019-11760)

  - By using a form with a data URI it was possible to gain     access to the privileged JSONView object that had been     cloned into content. Impact from exposing this object     appears to be minimal, however it was a bypass of     existing defense in depth mechanisms. This vulnerability     affects Firefox < 70, Thunderbird < 68.2, and Firefox     ESR < 68.2. (CVE-2019-11761)

  - Under certain conditions, when checking the Resist     Fingerprinting preference during device orientation     checks, a race condition could have caused a use-after-     free and a potentially exploitable crash. This     vulnerability affects Thunderbird < 68.3, Firefox ESR <     68.3, and Firefox < 71. (CVE-2019-17010)

  - Under certain conditions, when retrieving a document     from a DocShell in the antitracking code, a race     condition could cause a use-after-free condition and a     potentially exploitable crash. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17011)

  - Mozilla developers reported memory safety bugs present     in Firefox 70 and Firefox ESR 68.2. Some of these bugs     showed evidence of memory corruption and we presume that     with enough effort some of these could have been     exploited to run arbitrary code. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17012)

  - When using nested workers, a use-after-free could occur     during worker destruction. This resulted in a     potentially exploitable crash. This vulnerability     affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-17008)

  - The plain text serializer used a fixed-size array for     the number of  elements it could process; however it     was possible to overflow the static-sized array leading     to memory corruption and a potentially exploitable     crash. This vulnerability affects Thunderbird < 68.3,     Firefox ESR < 68.3, and Firefox < 71. (CVE-2019-17005)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Several memory safety bugs were discovered in Mozilla Firefox and Thunderbird. Memory corruption and arbitrary code execution are possible with these vulnerabilities. These bugs can be exploited over the network.(CVE-2019-11764)

A flaw was discovered in both Firefox and Thunderbird where 4 bytes of a HMAC output could be written past the end of a buffer stored on the memory stack. This could allow an attacker to execute arbitrary code or lead to a crash. This flaw can be exploited over the network.(CVE-2019-11759)

A flaw was found in Mozilla Firefox and Thunderbird where null bytes were incorrectly parsed in HTML entities. This could lead to HTML comments being treated as code which could lead to XSS in a web application or HTML entities being masked from filters.(CVE-2019-11763)

A vulnerability was found in Mozilla Firefox and Thunderbird.
Privileged JSONView objects that have been cloned into content can be accessed using a form with a data URI. This flaw bypasses existing defense-in-depth mechanisms and can be exploited over the network.(CVE-2019-11761)

A flaw was discovered in Mozilla Firefox and Thunderbird where a fixed-stack buffer overflow could occur during WebRTC signalling. The vulnerability could lead to an exploitable crash or leak data.(CVE-2019-11760)

A use-after-free flaw was found in Mozilla Firefox and Thunderbird.
When following a value's prototype chain, it was possible to retain a reference to a locale, delete it, and subsequently reference it. An attacker could use this flaw to execute code that was stored in the referenced memory or crash the system.(CVE-2019-11757)

In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.(CVE-2019-15903)

A flaw was found in Mozilla's firefox and thunderbird where if two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross-origin window. This could cause an interaction between two different sites on two different windows running under the same application.(CVE-2019-11762)

A flaw was found in the 360 Total Security code in Firefox and Thunderbird. Memory corruption is possible in the accessibility engine that could lead to an exploit to run arbitrary code. This vulnerability could be exploited over a network connection and would affect confidentiality and integrity of information as well as availability of the system.(CVE-2019-11758)
