High
| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 101
Firefox ESR versions prior to 91.10
Thunderbird versions prior to 91.10
Description
The issue arises from the failure to escape the % character when downloading files on Windows, potentially leading to downloads being saved to attacker-influenced paths using variables such as
%HOMEPATH% or %APPDATA%. This could result in an attacker being able to influence the path where a file is saved, potentially leading to security issues. The vulnerability is specific to Windows and does not affect other operating systems.Recommendations
For Firefox versions prior to 101, update to version 101 or later to resolve the issue.
For Firefox ESR versions prior to 91.10, update to version 91.10 or later to resolve the issue.
For Thunderbird versions prior to 91.10, update to version 91.10 or later to resolve the issue.
As a temporary workaround, consider avoiding the use of the
% character in download paths until a patch is applied.Exploit
