{"id":"AZL-11653","summary":"CVE-2022-23527 affecting package mod_auth_openidc for versions less than 2.4.14.2-1","details":"mod_auth_openidc is an OpenID Certified™ authentication and authorization module for the Apache 2.x HTTP server. Versions prior to 2.4.12.2 are vulnerable to Open Redirect. When providing a logout parameter to the redirect URI, the existing code in oidc_validate_redirect_url() does not properly check for URLs that start with /\\t, leading to an open redirect. This issue has been patched in version 2.4.12.2. Users unable to upgrade can mitigate the issue by configuring mod_auth_openidc to only allow redirection when the destination matches a given regular expression with OIDCRedirectURLsAllowed.","modified":"2026-04-01T05:07:15.319298Z","published":"2022-12-14T18:15:20Z","upstream":["CVE-2022-23527"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23527"}],"affected":[{"package":{"name":"mod_auth_openidc","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/mod_auth_openidc"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.14.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-11653.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
