An attacker could exploit this vulnerability by sending a crafted HTTP request that contains directory traversal character sequences to an affected system. A successful exploit could allow the attacker to access sensitive files on the affected system.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.","published":"2024-11-18T16:15:08.000Z","lastModified":"2026-06-17T03:31:01.000Z","status":"Analyzed","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-35"],"affected":["cisco/network services orchestrator"],"epss":{"score":0.01629,"percentile":0.76015,"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 (1.63%).
