An unauthenticated, remote attacker could exploit this vulnerability to perform sensitive actions such as adding a new administrator account or changing the appliance’s settings. A malicious internal user could also gain administrator privileges of this appliance and use it to visit a malicious link that exploits this vulnerability. This could cause the application to perform sensitive actions such as adding a new administrator account or changing the appliance’s settings. An unauthenticated, remote attacker could add an administrator-level account or change the appliance's settings.","published":"2019-06-03T19:29:02.000Z","lastModified":"2026-06-17T02:00:16.000Z","status":"Modified","sourceIdentifier":"cret@cert.org","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-284"],"affected":["quest/kace systems management appliance firmware"],"epss":{"score":0.12206,"percentile":0.96146,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":true,"firstPublished":"2019-06-03","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":46956,"kind":"exploit","title":"KACE System Management Appliance (SMA) < 9.0.270 - Multiple Vulnerabilities","url":"https://www.exploit-db.com/exploits/46956","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/php/webapps/46956.txt","file":"exploits/php/webapps/46956.txt","published":"2019-06-03","added":"2019-06-03","updated":"2019-06-03","author":"SlidingWindow","type":"webapps","platform":"php","port":null,"verified":true,"codes":["CVE-2018-5406","CVE-2018-5405","CVE-2018-5404"],"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 12.2%, higher than 96% of all known CVEs.
