CVE-2023-4052

CVE-2023-4052, medium severity (CVSS 6.5): 1 tracked app concerned, all fixed or indeterminable on their current version.

Severity (CVSS): 6.5
Exploitation: -
Tracked apps: 1
Still exposed: 0

Published on 2023-08-01

The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user.
*This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and Thunderbird < 115.1.
