Attackers holding a trusted-CA-chained certificate can make OpenAM request internal hosts, capture configured CRL update credentials, overwrite stored revocation data to block certificate authentication for that CA, and tie up authentication threads.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-g5vw-v384-gw9v","tags":[]},{"url":"https://www.vulncheck.com/advisories/openam-before-16.1.4-ssrf-and-crl-tampering-via-certificate-crl-distribution-point","tags":[]}],"exploitRefs":[{"url":"https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-g5vw-v384-gw9v","tags":[]}],"hasPoc":true,"ai":null}
