To exploit this vulnerability, the attacker must have valid credentials on the system.\r\n\r\nThis vulnerability is due to insufficient input validation of the HTTPS URL by the web-based management interface. An attacker could exploit this vulnerability by sending a crafted request that contains directory traversal character sequences to an affected device. A successful exploit could allow the attacker to write arbitrary files to the host system.\r\nCisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.","published":"2024-11-15T16:15:21.000Z","lastModified":"2026-06-17T04:24:48.000Z","status":"Analyzed","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-24"],"affected":["cisco/prime infrastructure","cisco/evolved programmable network manager"],"epss":{"score":0.01694,"percentile":0.7696,"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":"low","text":"Lower severity and a low EPSS score (1.69%).
