The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Mozilla: Type confusion for special arguments in IonMonkey (CVE-2020-15656)

  - Mozilla: Malicious Extension could obtain auth codes from OAuth login flows (CVE-2020-6823)

  - Mozilla Firefox before 35.0 and SeaMonkey before 2.32 do not consider the id-pkix-ocsp-nocheck extension     in deciding whether to trust an OCSP responder, which makes it easier for remote attackers to obtain     sensitive information by sniffing the network during a session in which there was an incorrect decision to     accept a compromised and revoked certificate. (CVE-2014-8642)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Mozilla: Type confusion for special arguments in IonMonkey (CVE-2020-15656)

  - Mozilla: Malicious Extension could obtain auth codes from OAuth login flows (CVE-2020-6823)

  - Mozilla Firefox through 27 sends HTTP Cookie headers without first validating that they have the required     character-set restrictions, which allows remote attackers to conduct the equivalent of a persistent Logout     CSRF attack via a crafted parameter that forces a web application to set a malformed cookie within an HTTP     response. (CVE-2013-6167)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 69.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-25 advisory.

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

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 obtain sensitive information, bypass Content Security Policy (CSP) protections, bypass same-origin restrictions, conduct cross-site scripting (XSS) attacks, cause a denial of service, or execute arbitrary code. (CVE-2019-5849, CVE-2019-11734, CVE-2019-11735, CVE-2019-11737, CVE-2019-11738, CVE-2019-11740, CVE-2019-11742, CVE-2019-11743, CVE-2019-11744, CVE-2019-11746, CVE-2019-11748, CVE-2019-11749, CVE-2019-11750, CVE-2019-11752)

It was discovered that a compromised content process could log in to a malicious Firefox Sync account. An attacker could potentially exploit this, in combination with another vulnerability, to disable the sandbox. (CVE-2019-9812)

It was discovered that addons.mozilla.org and accounts.firefox.com could be loaded in to the same content process. An attacker could potentially exploit this, in combination with another vulnerability that allowed a cross-site scripting (XSS) attack, to modify browser settings. (CVE-2019-11741)

It was discovered that the 'Forget about this site' feature in the history pane removes HTTP Strict Transport Security (HSTS) settings for sites on the pre-load list. An attacker could potentially exploit this to bypass the protections offered by HSTS. (CVE-2019-11747).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of Firefox installed on the remote Windows host is prior to 69.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-25 advisory.

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

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - Mozilla: Type confusion for special arguments in IonMonkey (CVE-2020-15656)

  - Mozilla: Malicious Extension could obtain auth codes from OAuth login flows (CVE-2020-6823)

  - By using the reflected URL in some special resource URIs, such as chrome:, it is possible to inject     stylesheets and bypass Content Security Policy (CSP). This vulnerability affects Firefox < 63.
    (CVE-2018-12398)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
