Name of the Vulnerable Software and Affected Versions cifs-utils (affected versions not specified)

Description The issue is related to the mount.cifs command in cifs-utils, which invokes a shell when requesting the Samba password. This could allow an attacker to inject arbitrary commands, potentially leading to privilege escalation if the command is invoked with special permissions, such as via sudo rules. The vulnerability is also associated with a lack of input sanitization, which could enable an attacker to access confidential data, compromise its integrity, and cause a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
