The vulnerability is due to insufficient request header validation during the authentication process. An attacker could exploit this vulnerability by sending a series of malicious requests to an affected device. An exploit could allow the attacker to use the acquired session token to gain full administrator access to the affected device.","published":"2019-08-21T19:15:15.000Z","lastModified":"2026-06-17T02:29:39.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","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-287"],"affected":["cisco/integrated management controller supervisor","cisco/ucs director","cisco/ucs director express for big data"],"epss":{"score":0.75863,"percentile":0.99523,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2023-07-15","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":51589,"kind":"exploit","title":"Cisco UCS-IMC Supervisor 2.2.0.0 - Authentication Bypass","url":"https://www.exploit-db.com/exploits/51589","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/hardware/webapps/51589.txt","file":"exploits/hardware/webapps/51589.txt","published":"2023-07-15","added":"2023-07-15","updated":"2023-07-15","author":"Fatih Sencer","type":"webapps","platform":"hardware","port":null,"verified":false,"codes":["CVE-2019-1937"],"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 75.9%, higher than 100% of all known CVEs.
