The vulnerability is due to the presence of a documented default account with an undocumented default password and incorrect permission settings for that account. Changing the default password for this account is not enforced during the installation of the product. An attacker could exploit this vulnerability by using the account to log in to an affected system. A successful exploit could allow the attacker to execute arbitrary commands with the privileges of the scpuser account. This includes full read and write access to the system's database.","published":"2019-08-21T19:15:15.000Z","lastModified":"2026-06-17T02:29:38.000Z","status":"Modified","sourceIdentifier":"psirt@cisco.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-798"],"affected":["cisco/integrated management controller supervisor","cisco/ucs director","cisco/ucs director express for big data"],"epss":{"score":0.83386,"percentile":0.99678,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":true,"firstPublished":"2019-09-03","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":47346,"kind":"exploit","title":"Cisco UCS Director - default scpuser password (Metasploit)","url":"https://www.exploit-db.com/exploits/47346","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/unix/remote/47346.rb","file":"exploits/unix/remote/47346.rb","published":"2019-09-03","added":"2019-09-03","updated":"2019-09-03","author":"Metasploit","type":"remote","platform":"unix","port":22,"verified":true,"codes":["CVE-2019-1935"],"tags":"Metasploit Framework (MSF)","aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/exploits/linux/ssh/cisco_ucs_scpuser.rb"}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 83.4%, higher than 100% of all known CVEs.
