The vulnerability is due to improper validation of user-supplied input data by the web-based management interface. An attacker could exploit this vulnerability by sending crafted requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary code with the privileges of the root user.","published":"2020-07-16T18:15:17.000Z","lastModified":"2026-06-17T03:17:59.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-119"],"affected":["cisco/rv110w wireless-n vpn firewall firmware","cisco/rv215w wireless-n vpn router firmware"],"epss":{"score":0.417,"percentile":0.98678,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 41.7%, higher than 99% of all known CVEs.
