{"id":"CVE-2024-47832","state":"PUBLISHED","title":"XML Signature Bypass via differential XML parsing in ssoready","description":"ssoready is a single sign on provider implemented via docker. Affected versions are vulnerable to XML signature bypass attacks. 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. Users 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. There are no known workarounds for this vulnerability.","publishedAt":"2024-10-09T18:32:19.800Z","updatedAt":"2024-10-11T16:58:48.177Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["ssoready ssoready"],"affected":[{"vendor":"ssoready","product":"ssoready","versions":[{"version":"< 0.0.0-20241009153838-7f92a0630439","status":"affected"}]}],"references":["https://github.com/ssoready/ssoready/security/advisories/GHSA-j2hr-q93x-gxvh","https://github.com/ssoready/ssoready/commit/7f92a0630439972fcbefa8c7eafe8c144bd89915","https://ssoready.com/docs/self-hosting/self-hosting-sso-ready"],"weaknesses":["CWE-347"],"ingestedAt":"2026-10-29T20:07:56.516Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/47xxx/CVE-2024-47832.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-47832","state":"PUBLISHED","datePublished":"2024-10-09T18:32:19.800Z","dateUpdated":"2024-10-11T16:58:48.177Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2024-10-03T14:06:12.643Z"},"containers":{"cna":{"title":"XML Signature Bypass via differential XML parsing in ssoready","descriptions":[{"lang":"en","value":"ssoready is a single sign on provider implemented via docker.
