Attackers can exploit the POST/PUT /api/identity-providers endpoint with no validation of target host, IP, or scheme to perform internal network port scanning and access cloud instance-metadata services.","cvssScore":5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/UTMStack/UTMStack/releases/tag/v11.2.16","tags":[]},{"url":"https://github.com/utmstack/UTMStack/commit/4e7a727c3b8d8e2ad020d3b4f982a6d085dbecdd","tags":[]},{"url":"https://www.vulncheck.com/advisories/utmstack-ssrf-via-identityproviderservice","tags":[]}],"exploitRefs":[{"url":"https://github.com/UTMStack/UTMStack/releases/tag/v11.2.16","tags":[]},{"url":"https://github.com/utmstack/UTMStack/commit/4e7a727c3b8d8e2ad020d3b4f982a6d085dbecdd","tags":[]}],"hasPoc":true,"ai":null}
