An attacker with low-privileged access to an affected device could exploit this vulnerability by issuing a crafted SSH client command to the CLI. A successful exploit could allow the attacker to elevate privileges to root on the affected device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
