The version of Thunderbird installed on the remote Windows host is prior to 78.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-29 advisory.

  - When %2F was present in a manifest URL, Firefox's     AppCache behavior may have become confused and allowed a     manifest to be served from a subdirectory. This could     cause the appcache to be used to service requests for     the top level directory. This vulnerability affects     Firefox < 78. (CVE-2020-12415)

  - A VideoStreamEncoder may have been freed in a race     condition with VideoBroadcaster::AddOrUpdateSink,     resulting in a use-after-free, memory corruption, and a     potentially exploitable crash. This vulnerability     affects Firefox < 78. (CVE-2020-12416)

  - Due to confusion about ValueTags on JavaScript Objects,     an object may pass through the type barrier, resulting     in memory corruption and a potentially exploitable     crash. *Note: this issue only affects Firefox on ARM64     platforms.* This vulnerability affects Firefox ESR <     68.10, Firefox < 78, and Thunderbird < 68.10.0.
    (CVE-2020-12417)

  - Manipulating individual parts of a URL object could have     caused an out-of-bounds read, leaking process memory to     malicious JavaScript. This vulnerability affects Firefox     ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
    (CVE-2020-12418)

  - When processing callbacks that occurred during window     flushing in the parent process, the associated window     may die; causing a use-after-free condition. This could     have led to memory corruption and a potentially     exploitable crash. This vulnerability affects Firefox     ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
    (CVE-2020-12419)

  - When trying to connect to a STUN server, a race     condition could have caused a use-after-free of a     pointer, leading to memory corruption and a potentially     exploitable crash. This vulnerability affects Firefox     ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
    (CVE-2020-12420)

  - During RSA key generation, bignum implementations used a     variation of the Binary Extended Euclidean Algorithm     which entailed significantly input-dependent flow. This     allowed an attacker able to perform electromagnetic-     based side channel attacks to record traces leading to     the recovery of the secret primes. *Note:* An unmodified     Firefox browser does not generate RSA keys in normal     operation and is not affected, but products built on top     of it might. This vulnerability affects Firefox < 78.
    (CVE-2020-12402)

  - When performing add-on updates, certificate chains     terminating in non-built-in-roots were rejected (even if     they were legitimately added by an administrator.) This     could have caused add-ons to become out-of-date silently     without notification to the user. This vulnerability     affects Firefox ESR < 68.10, Firefox < 78, and     Thunderbird < 68.10.0. (CVE-2020-12421)

  - In non-standard configurations, a JPEG image created by     JavaScript could have caused an internal variable to     overflow, resulting in an out of bounds write, memory     corruption, and a potentially exploitable crash. This     vulnerability affects Firefox < 78. (CVE-2020-12422)

  - When the Windows DLL webauthn.dll was missing from the     Operating System, and a malicious one was placed in a     folder in the user's %PATH%, Firefox may have loaded the     DLL, leading to arbitrary code execution. *Note: This     issue only affects the Windows operating system; other     operating systems are unaffected.* This vulnerability     affects Firefox < 78. (CVE-2020-12423)

  - When constructing a permission prompt for WebRTC, a URI     was supplied from the content process. This URI was     untrusted, and could have been the URI of an origin that     was previously granted permission; bypassing the prompt.
    This vulnerability affects Firefox < 78.
    (CVE-2020-12424)

  - Due to confusion processing a hyphen character in     Date.parse(), a one-byte out of bounds read could have     occurred, leading to potential information disclosure.
    This vulnerability affects Firefox < 78.
    (CVE-2020-12425)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 77. 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 Firefox < 78. (CVE-2020-12426)

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

The remote NewStart CGSL host, running version MAIN 6.02, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier,     resulting in memory corruption and a potentially exploitable crash. *Note: this issue only affects Firefox     on ARM64 platforms.* This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird <     68.10.0. (CVE-2020-12417)

  - Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process     memory to malicious JavaScript. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and     Thunderbird < 68.10.0. (CVE-2020-12418)

  - When processing callbacks that occurred during window flushing in the parent process, the associated     window may die; causing a use-after-free condition. This could have led to memory corruption and a     potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and     Thunderbird < 68.10.0. (CVE-2020-12419)

  - When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even     if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date     silently without notification to the user. This vulnerability affects Firefox ESR < 68.10, Firefox < 78,     and Thunderbird < 68.10.0. (CVE-2020-12421)

  - Use after free in ANGLE in Google Chrome prior to 81.0.4044.122 allowed a remote attacker to potentially     exploit heap corruption via a crafted HTML page. (CVE-2020-6463)

  - Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a     privileged network position to potentially exploit heap corruption via a crafted SCTP stream.
    (CVE-2020-6514)

  - By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a     cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability     affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird <     78.1. (CVE-2020-15652)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR     78.0. 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 Firefox < 79, Firefox     ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1. (CVE-2020-15659)

  - By holding a reference to the eval() function from an about:blank window, a malicious webpage could have     gained access to the InstallTrigger object which would allow them to prompt the user to install an     extension. Combined with user confusion, this could result in an unintended or malicious extension being     installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR <     68.12, Firefox ESR < 78.2, and Firefox for Android < 80. (CVE-2020-15664)

  - When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to     be notified. This results in a use-after-free and we presume that with enough effort it could have been     exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.
    (CVE-2020-15669)

  - If an attacker intercepts Thunderbird's initial attempt to perform automatic account setup using the     Microsoft Exchange autodiscovery mechanism, and the attacker sends a crafted response, then Thunderbird     sends username and password over https to a server controlled by the attacker. This vulnerability affects     Thunderbird < 68.10.0. (CVE-2020-15646)

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