The vulnerability is due to improper authentication request handling. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow an unprivileged attacker to access and execute arbitrary actions through certain APIs. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
