Questions about CVE-2022-20699
What does this mean?
A flaw in the SSL VPN module lets a remote attacker who has not logged in run code with root privileges on the device. The advisory describes this as arbitrary code execution.Source: sec.cloudapps.cisco.com
Am I affected, and how do I check?
The advisory names the RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers, and only when the device is acting as an SSL VPN Gateway. To check a router's setup, look at whether its SSL VPN gateway feature is enabled in the admin interface. The facts do not list affected firmware versions.Source: sec.cloudapps.cisco.com
What should I do about it?
The facts do not name a fixed firmware release. Check Cisco's security advisory for CVE-2022-20699 for the fixed version and update to it when one is published.Source: sec.cloudapps.cisco.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-03-03, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
What if there's no patch?
The facts do not give an official workaround. Turning off the SSL VPN gateway feature would remove the setup the advisory describes, but confirm this against Cisco's advisory before relying on it.Source: sec.cloudapps.cisco.com
