CVE-2023-29532

CVE-2023-29532, medium severity (CVSS 5.5): 2 tracked apps concerned, all fixed or indeterminable on their current version.

Severity (CVSS): 5.5
Exploitation: 0.2 %
Tracked apps: 2
Still exposed: 0

Published on 2023-06-19

A local attacker can trick the Mozilla Maintenance Service into applying an unsigned update file by pointing the service at an update file on a malicious SMB server. The update file can be replaced after the signature check, before the use, because the write-lock requested by the service does not work on a SMB server.

*Note: This attack requires local system access and only affects Windows. Other operating systems are not affected.* This vulnerability affects Firefox < 112, Firefox ESR < 102.10, and Thunderbird < 102.10.
