The vulnerability is due to insufficient validation of user-supplied input to the TAPS interface of the affected device. An attacker could exploit this vulnerability by sending a crafted request to the TAPS interface. A successful exploit could allow the attacker to read arbitrary files in the system. Cisco has released software updates that address the vulnerability described in this advisory. There are no workarounds that address this vulnerability.
