An attacker could exploit this vulnerability by uploading a crafted file to the affected device. A successful exploit could allow the attacker to store malicious files on the affected system and then execute arbitrary code or obtain root privileges on the system.","published":"2025-06-25T17:15:37.000Z","lastModified":"2026-06-17T08:41:21.000Z","status":"Analyzed","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":10,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-269"],"affected":["cisco/identity services engine","cisco/identity services engine passive identity connector"],"epss":{"score":0.38719,"percentile":0.98582,"date":"2026-11-01","history":[{"date":"2026-09-24","score":0.29303,"percentile":0.98113},{"date":"2026-09-26","score":0.38719,"percentile":0.98536}]},"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 38.7%, higher than 99% of all known CVEs.
