An attacker can carry out signature bypass if you have access to certain IDP-signed messages. The underlying mechanism exploits differential behavior between XML parsers.\n\nUsers of https://ssoready.com, the public hosted instance of SSOReady, are unaffected. We advise folks who self-host SSOReady to upgrade to 7f92a06 or later. Do so by updating your SSOReady Docker images from `sha-...` to `sha-7f92a06`. The documentation for self-hosting SSOReady is available [here](https://ssoready.com/docs/self-hosting/self-hosting-sso-ready).\n\nVulnerability was discovered by @ahacker1-securesaml. It's likely the precise mechanism of attack affects other SAML implementations, so the reporter and I (@ucarion) have agreed to not disclose it in detail publicly at this time.","affected":[{"package":{"name":"github.com/ssoready/ssoready","ecosystem":"Go","purl":"pkg:golang/github.com/ssoready/ssoready"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.0.0-20241009153838-7f92a0630439"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/10/GHSA-j2hr-q93x-gxvh/GHSA-j2hr-q93x-gxvh.json"}}],"references":[{"type":"WEB","url":"https://github.com/ssoready/ssoready/security/advisories/GHSA-j2hr-q93x-gxvh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-47832"},{"type":"WEB","url":"https://github.com/ssoready/ssoready/commit/7f92a0630439972fcbefa8c7eafe8c144bd89915"},{"type":"PACKAGE","url":"https://github.com/ssoready/ssoready"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2024-3185"},{"type":"WEB","url":"https://ssoready.com/docs/self-hosting/self-hosting-sso-ready"}],"database_specific":{"cwe_ids":["CWE-347"],"github_reviewed":true,"github_reviewed_at":"2024-10-11T16:58:36Z","nvd_published_at":"2024-10-09T19:15:14Z","severity":"CRITICAL"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
