Cisco Patched Secure Web Appliance Vulnerability

Cisco has patched a high-severity escalation of privilege vulnerability in AsyncOS for Cisco Secure Web Appliance.

Cisco’s Secure Web Appliance is an enterprise protection solution designed to block risky sites and provide application visibility and control.

The flaw tracked as CVE-2022-20871can be exploited remotely to inject commands and escalate privileges to root, but requires authentication for successful exploitation.

The security bug exists because user-supplied input for the web interface is not sufficiently validated. The attacker needs to have at least read-only credentials to successfully exploit the issue.
