Descriptions

A flaw was found in the samba client, all samba versions before samba 4.11.2, 4.10.10 and 4.9.15, where a malicious server can supply a pathname to the client with separators. This could allow the client to access files and folders outside of the SMB network pathnames. An attacker could use this vulnerability to create files outside of the current working directory using the privileges of the client user.

Se encontró un fallo en el cliente de samba, todas las versiones de samba anteriores a samba 4.11.2, 4.10.10 y 4.9.15, donde un servidor malicioso puede suministrar un nombre de ruta al cliente con separadores. Esto podría permitir al cliente acceder a archivos y carpetas fuera de los nombres de ruta de la red SMB. Un atacante podría usar esta vulnerabilidad para crear archivos fuera del directorio de trabajo actual usando los privilegios de usuario del cliente.
