How to fix?

There is no fixed version for Debian:10 cifs-utils.

NVD Description

Note: Versions mentioned in the description apply only to the upstream cifs-utils package and not the cifs-utils package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

It was found that cifs-utils' mount.cifs was invoking a shell when requesting the Samba password, which could be used to inject arbitrary commands. An attacker able to invoke mount.cifs with special permission, such as via sudo rules, could use this flaw to escalate their privileges.
