This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by executing a directory traversal attack on an affected host. A successful exploit could allow an attacker to use a cryptographic key to overwrite arbitrary files with SYSTEM-level privileges, resulting in a denial of service (DoS) condition or data loss on the affected system. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
