Mozilla Firefox ESR < 91.9.1

high Nessus Plugin ID 161414

Language:

Synopsis

A web browser installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote Windows host is prior to 91.9.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-19 advisory.

 - If an attacker was able to corrupt the methods of an Array object in JavaScript via prototype pollution, they could have achieved execution of attacker-controlled JavaScript code in a privileged context.
 (CVE-2022-1802)

 - An attacker could have sent a message to the parent process where the contents were used to double-index into a JavaScript object, leading to prototype pollution and ultimately attacker-controlled JavaScript executing in the privileged parent process. (CVE-2022-1529)

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

Solution

Upgrade to Mozilla Firefox ESR version 91.9.1 or later.
