CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to insufficient validation of shell commands that are used in the name of a mountpoint. A local attacker can embed crafted shell commands in the name of a mountpoint. If another user on the system executes the umount command along with a tab character for autocomplete, the attacker can gain elevated privileges.
