The attacker must be authenticated on the affected device as a low-privileged user to exploit this vulnerability. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by injecting arbitrary commands to a file as a lower-privileged user. The commands are then executed on the device by the root user. A successful exploit could allow the attacker to execute arbitrary commands as the root user. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
