The version of Firefox ESR installed on the remote Windows host is prior to 68.3. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-37 advisory.

  - Mozilla developers Christoph Diehl, Nathan Froyd, Jason Kratzer, Christian Holler, Karl Tomlinson, Tyson     Smith 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. (CVE-2019-17012)

  - When using nested workers, a use-after-free could occur during worker destruction. This resulted in a     potentially exploitable crash. (CVE-2019-17008)

  - When setting a thread name on Windows in WebRTC, an incorrect number of arguments could have been     supplied, leading to stack corruption and a potentially exploitable crash.   Note: this issue only occurs     on Windows. Other operating systems are unaffected. (CVE-2019-13722)

  - When encrypting with a block cipher, if a call to <code>NSCEncryptUpdate</code> was made with data smaller     than the block size, a small out of bounds write could occur. This could have caused heap corruption and a     potentially exploitable crash. (CVE-2019-11745)

  - When running, the updater service wrote status and log files to an unrestricted location; potentially     allowing an unprivileged process to locate and exploit a vulnerability in file handling in the updater     service.   Note: This attack requires local system access and only affects Windows. Other operating     systems are not affected. (CVE-2019-17009)

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