In affected versions missing input validation on mod_auth_openidc_session_chunks cookie value makes the server vulnerable to a denial of service (DoS) attack. An internal security audit has been conducted and the reviewers found that if they manipulated the value of the mod_auth_openidc_session_chunks cookie to a very large integer, like 99999999, the server struggles with the request for a long time and finally gets back with a 500 error. Making a few requests of this kind caused our server to become unresponsive. Attackers can craft requests that would make the server work very hard (and possibly become unresponsive) and/or crash with minimal effort. This issue has been addressed in version 2.4.15.2. Users are advised to upgrade. There are no known workarounds for this vulnerability."}],"source":{"advisory":"GHSA-hxr6-w4gc-7vvv","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-01T23:28:12.661Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/OpenIDC/mod_auth_openidc/security/advisories/GHSA-hxr6-w4gc-7vvv","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/OpenIDC/mod_auth_openidc/security/advisories/GHSA-hxr6-w4gc-7vvv"},{"name":"https://github.com/OpenIDC/mod_auth_openidc/commit/4022c12f314bd89d127d1be008b1a80a08e1203d","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/OpenIDC/mod_auth_openidc/commit/4022c12f314bd89d127d1be008b1a80a08e1203d"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/T7DKVEVREYAI4F46CQAVOTPL75WLOZOE/","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2024/03/msg00004.html","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-04-10T18:58:12.898280Z","id":"CVE-2024-24814","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-04-10T19:00:12.439Z"}}]}}
