In versions prior to 2.4.9.4, the 3rd-party init SSO functionality of mod_auth_openidc was reported to be vulnerable to an open redirect attack by supplying a crafted URL in the `target_link_uri` parameter. A patch in version 2.4.9.4 made it so that the `OIDCRedirectURLsAllowed` setting must be applied to the `target_link_uri` parameter. There are no known workarounds aside from upgrading to a patched version."}],"affected":[{"vendor":"zmartzone","product":"mod_auth_openidc","versions":[{"version":"<=2.4.9.3","status":"affected"}]}],"references":[{"url":"https://github.com/zmartzone/mod_auth_openidc/security/advisories/GHSA-2pgf-8h6h-gqg2"},{"url":"https://github.com/zmartzone/mod_auth_openidc/issues/672"},{"url":"https://github.com/zmartzone/mod_auth_openidc/commit/03e6bfb446f4e3f27c003d30d6a433e5dd8e2b3d"},{"url":"https://github.com/zmartzone/mod_auth_openidc/releases/tag/v2.4.9.4"},{"name":"FEDORA-2021-8d9aca2ded","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/32RGPW5LZDLDTB7MKZIGAHPSLFOUNWR5/"},{"name":"FEDORA-2022-814ee0c43b","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RHXO4O4G2UQS7X6OQJCVZKHZAQ7SAIFB/"},{"name":"[debian-lts-announce] 20230718 [SECURITY] [DLA 3499-1] libapache2-mod-auth-openidc security update","tags":["mailing-list"],"url":"https://lists.debian.org/debian-lts-announce/2023/07/msg00020.html"}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE","baseScore":4.7,"baseSeverity":"MEDIUM"}}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-601: URL Redirection to Untrusted Site ('Open Redirect')","cweId":"CWE-601"}]}],"source":{"advisory":"GHSA-2pgf-8h6h-gqg2","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-04T01:58:18.283Z"},"title":"CVE Program Container","references":[{"url":"https://github.com/zmartzone/mod_auth_openidc/security/advisories/GHSA-2pgf-8h6h-gqg2","tags":["x_transferred"]},{"url":"https://github.com/zmartzone/mod_auth_openidc/issues/672","tags":["x_transferred"]},{"url":"https://github.com/zmartzone/mod_auth_openidc/commit/03e6bfb446f4e3f27c003d30d6a433e5dd8e2b3d","tags":["x_transferred"]},{"url":"https://github.com/zmartzone/mod_auth_openidc/releases/tag/v2.4.9.4","tags":["x_transferred"]},{"name":"FEDORA-2021-8d9aca2ded","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/32RGPW5LZDLDTB7MKZIGAHPSLFOUNWR5/"},{"name":"FEDORA-2022-814ee0c43b","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RHXO4O4G2UQS7X6OQJCVZKHZAQ7SAIFB/"},{"name":"[debian-lts-announce] 20230718 [SECURITY] [DLA 3499-1] libapache2-mod-auth-openidc security update","tags":["mailing-list","x_transferred"],"url":"https://lists.debian.org/debian-lts-announce/2023/07/msg00020.html"}]}]}}
