A redirected HTTP request which is observed or modified through a web extension could bypass existing CORS checks, leading to potential disclosure of cross-origin information. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A redirected HTTP request which is observed or modified through a web extension could bypass existing CORS     checks, leading to potential disclosure of cross-origin information. This vulnerability affects Firefox     ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15655)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14456-1 advisory.

  - 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)

  - An iframe sandbox element with the allow-popups flag could be bypassed when using noopener links. This     could have led to security issues for websites relying on sandbox configurations that allowed popups and     hosted arbitrary content. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird <     78.1. (CVE-2020-15653)

  - When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user     is interacting with the user interface, when they are not. This could lead to a perceived broken state,     especially when interactions with existing browser dialogs and warnings do not work. This vulnerability     affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15654)

  - A redirected HTTP request which is observed or modified through a web extension could bypass existing CORS     checks, leading to potential disclosure of cross-origin information. This vulnerability affects Firefox     ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15655)

  - JIT optimizations involving the Javascript arguments object could confuse later optimizations. This risk     was already mitigated by various precautions in the code, resulting in this bug rated at only moderate     severity. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
    (CVE-2020-15656)

  - Firefox could be made to load attacker-supplied DLL files from the installation directory. This required     an attacker that is already capable of placing files in the installation directory. *Note: This issue only     affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects     Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. (CVE-2020-15657)

  - The code for downloading files did not properly take care of special characters, which led to an attacker     being able to cut off the file ending at an earlier position, leading to a different file type being     downloaded than shown in the dialog. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and     Thunderbird < 78.1. (CVE-2020-15658)

  - 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)

  - 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)

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

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4443-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information, bypass iframe sandbox restrictions, confuse the user, or execute arbitrary code.
