Descriptions

The shadow_copy2_get_shadow_copy_data function in modules/vfs_shadow_copy2.c in Samba 3.x and 4.x before 4.1.22, 4.2.x before 4.2.7, and 4.3.x before 4.3.3 does not verify that the DIRECTORY_LIST access right has been granted, which allows remote attackers to access snapshots by visiting a shadow copy directory.

La función shadow_copy2_get_shadow_copy_data en modules/vfs_shadow_copy2.c en Samba 3.x y 4.x en versiones anteriores a 4.1.22, 4.2.x en versiones anteriores a 4.2.7 y 4.3.x en versiones anteriores a 4.3.3 no verifica que el privilegio de acceso al DIRECTORY_LIST ha sido concedido, lo que permite a atacantes remotos acceder a instantáneas visitando un directorio shadow copy.

A missing access control flaw was found in Samba. A remote, authenticated attacker could use this flaw to view the current snapshot on a Samba share, despite not having DIRECTORY_LIST access rights.
