The vulnerability is due to improper input validation in an NFVIS file-system command. An attacker could exploit this vulnerability by using crafted variables during the execution of an affected command. A successful exploit could allow the attacker to overwrite arbitrary files on the underlying OS. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
