An attacker could exploit this vulnerability by sending a crafted serialized Java object to an affected API. A successful exploit could allow the attacker to execute arbitrary commands on the device and elevate privileges.\r\nNote: To successfully exploit this vulnerability, the attacker must have valid read-only administrative credentials. In a single-node deployment, new devices will not be able to authenticate during the reload time.","published":"2025-02-05T17:15:22.000Z","lastModified":"2026-06-17T08:40:44.000Z","status":"Analyzed","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-502"],"affected":["cisco/identity services engine"],"epss":{"score":0.18476,"percentile":0.97223,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2025-08-11","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":52396,"kind":"exploit","title":"Cisco ISE 3.0 - Remote Code Execution (RCE)","url":"https://www.exploit-db.com/exploits/52396","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/multiple/remote/52396.py","file":"exploits/multiple/remote/52396.py","published":"2025-08-11","added":"2025-08-11","updated":"2025-08-11","author":"İbrahimsql","type":"remote","platform":"multiple","port":null,"verified":false,"codes":["CVE-2025-20124"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 18.5%, higher than 97% of all known CVEs.
