CVE-2023-4052 (GCVE-0-2023-4052)

Vulnerability from cvelistv5 – Published: 2023-08-01 14:59 – Updated: 2024-10-22 14:39
VLAI
Summary
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.
Severity
No CVSS data available.
CWE
