Questions about CVE-2022-20700
What does this mean?
Several flaws in the web-based management interface of these routers let a remote attacker elevate privileges to root. The impact is the ability to execute arbitrary commands on the affected system.Source: sec.cloudapps.cisco.com
Am I affected, and how do I check?
The affected products are the RV160, RV160W, RV260, RV260P, RV260W, RV340, RV340W, RV345, and RV345P series VPN routers. Compare your router's model name, found on the device label or in its web interface, with this list.Source: sec.cloudapps.cisco.com
What should I do about it?
The checked facts do not name a fixed firmware version, so no upgrade target is confirmed here. Check Cisco's advisory for the fixed release and the affected software versions.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 checked facts do not include a workaround. The vulnerable component is the web-based management interface, so follow the mitigation steps in Cisco's advisory for that interface.Source: sec.cloudapps.cisco.com
