The action_script parameter specifies a script to be executed if the action_mode parameter does not contain a valid state. If the input provided by action_script does not match one of the hard coded options, then it will be executed as the argument of either a system() or an eval() call allowing arbitrary commands to be executed.","published":"2018-07-13T20:29:01.000Z","lastModified":"2026-06-17T00:51:23.000Z","status":"Modified","sourceIdentifier":"cret@cert.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-77"],"affected":["asus/rp-ac52 firmware","asus/ea-n66 firmware","asus/rp-n12 firmware","asus/rp-n14 firmware","asus/rp-n53 firmware","asus/rp-ac56 firmware","asus/wmp-n12 firmware"],"epss":{"score":0.03503,"percentile":0.89091,"date":"2026-10-26","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 (3.50%).
