CVE-2022-20871

Summary

CVE-2022-20871 is a vulnerability affecting the web management interface of Cisco AsyncOS for Cisco Secure Web Appliance. This issue allows authenticated, remote attackers to execute command injections, potentially elevating privileges to root. The root cause is insufficient validation of user-supplied input. Attackers can exploit this by sending crafted HTTP packets to the affected device. Successful exploitation may lead to arbitrary command execution and system compromise. Cisco has released software updates to mitigate the risk, and currently there are no workarounds available. It's essential to apply the patches promptly as credentials with read-only access are sufficient for an attack. (Note: Cisco is in the process of simplifying its product portfolio under the Cisco Secure brand.)
