When processed, the commands will be executed with root privileges. The vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by providing malicious input to a specific field in the web-based management interface of an affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying Linux operating system as the root user.","published":"2020-09-23T01:15:13.000Z","lastModified":"2026-06-17T02:21:25.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":7.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-20"],"affected":["cisco/rv016 multi-wan vpn firmware","cisco/rv042 dual wan vpn","cisco/rv042g dual gigabit wan vpn firmware","cisco/rv082 dual wan vpn router firmware","cisco/rv320 firmware","cisco/rv325 firmware"],"epss":{"score":0.03246,"percentile":0.88249,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (3.25%).
