The version of Mozilla Firefox ESR installed on the remote Windows host is prior to 60.3. It is, therefore, affected by multiple vulnerabilities :

  - During HTTP Live Stream playback on Firefox for Android,     audio data can be accessed across origins in violation     of security policies. Because the problem is in the     underlying Android service, this issue is addressed by     treating all HLS streams as cross-origin and opaque to     access. *Note: this issue only affects Firefox for     Android. Desktop versions of Firefox are unaffected.*     (CVE-2018-12391)

  - When manipulating user events in nested loops while     opening a document through script, it is possible to     trigger a potentially exploitable crash due to poor     event handling. (CVE-2018-12392)

  - A potential vulnerability was found in 32-bit builds     where an integer overflow during the conversion of     scripts to an internal UTF-16 representation could     result in allocating a buffer too small for the     conversion. This leads to a possible out-of-bounds     write. *Note: 64-bit builds are not vulnerable to     this issue.* (CVE-2018-12393)

  - By rewriting the Host request headers using the     webRequest API, a WebExtension can bypass domain     restrictions through domain fronting. This would     allow access to domains that share a host that are     otherwise restricted. (CVE-2018-12395)

  - A vulnerability where a WebExtension can run content     scripts in disallowed contexts following navigation or     other events. This allows for potential privilege     escalation by the WebExtension on sites where content     scripts should not be run. (CVE-2018-12396)

  - A WebExtension can request access to local files     without the warning prompt stating that the extension     will 'Access your data for all websites' being displayed     to the user. This allows extensions to run content     scripts in local pages without permission warnings when     a local file is opened. (CVE-2018-12397)

  - Mozilla developers and community members Daniel     Veditz and Philipp reported memory safety bugs present     in Firefox ESR 60.2. 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. (CVE-2018-12389)

  - Mozilla developers and community members Christian     Holler, Bob Owen, Boris Zbarsky, Calixte Denizet, Jason     Kratzer, Jed Davis, Taegeon Lee, Philipp, Ronald Crane,     Raul Gurzau, Gary Kwong, Tyson Smith, Raymond Forbes,     and Bogdan Tara reported memory safety bugs present in     Firefox 62 and Firefox ESR 60.2. 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. (CVE-2018-12390)

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