CVE-2026-65711

sysPass through version 3.2.11 contains an OS command injection vulnerability that allows authenticated administrators to execute arbitrary commands as the web server process user by setting a malicious backup path and triggering a backup. The FileBackupService builds a tar shell command via string concatenation, inserting the admin-configurable siteBackupPath setting without escapeshellarg() or equivalent sanitization before passing it to exec(), causing injected commands to persist and execute on every subsequent backup trigger.

Summary		(es) sysPass hasta la versión 3.2.11 contiene una vulnerabilidad de inyección de comandos del sistema operativo que permite a los administradores autenticados ejecutar comandos arbitrarios como el usuario del proceso del servidor web al establecer una ruta de copia de seguridad maliciosa y activar una copia de seguridad. El FileBackupService construye un comando de shell tar mediante concatenación de cadenas, insertando la configuración siteBackupPath configurable por el administrador sin escapeshellarg() o una sanitización equivalente antes de pasarlo a exec(), lo que provoca que los comandos inyectados persistan y se ejecuten en cada activación de copia de seguridad posterior.
