CVE-2023-29532
Full vulnerability record from the local CVENow database.
Description
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.

El archivo de actualización puede ser reemplazado después de la verificación de firma, antes de su uso, porque el bloqueo de escritura solicitado por el servicio no funciona en un servidor SMB.\n\n*Nota: Este ataque requiere acceso local al sistema y solo afecta a Windows. Otros sistemas operativos no se ven afectados.* Esta vulnerabilidad afecta a Firefox < 112, Firefox ESR anterior a 102.10 y Thunderbird anterior a 102.10."
