CVE-2025-52995

Estado: AnalizadaMedia (6.6)—

File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to version 2.33.10, the implementation of the allowlist is erroneous, allowing a user to execute more shell commands than they are authorized for. The concrete impact of this vulnerability depends on the commands configured, and the binaries installed on the server or in the container image. Due to the missing separation of scopes on the OS-level, this could give an attacker access to all files managed the application, including the File Browser database. This issue has been patched in version 2.33.10.

En versiones anteriores a la 2.33.10, la implementación de la lista de permitidos era errónea, lo que permitía al usuario ejecutar más comandos de shell de los autorizados. El impacto concreto de esta vulnerabilidad depende de los comandos configurados y de los binarios instalados en el servidor o en la imagen del contenedor. Debido a la falta de separación de ámbitos a nivel del sistema operativo, esto podría dar a un atacante acceso a todos los archivos administrados por la aplicación, incluida la base de datos del Explorador de Archivos. Este problema se ha corregido en la versión 2.33.10."
