{"id":"CVE-2025-23048","details":"In some mod_ssl configurations on Apache HTTP Server 2.4.35 through to 2.4.63, an access control bypass by trusted clients is possible using TLS 1.3 session resumption.\n\nConfigurations are affected when mod_ssl is configured for multiple virtual hosts, with each restricted to a different set of trusted client certificates (for example with a different SSLCACertificateFile/Path setting). In such a case, a client trusted to access one virtual host may be able to access another virtual host, if SSLStrictSNIVHostCheck is not enabled in either virtual host.","aliases":["BIT-apache-2025-23048"],"modified":"2026-04-16T04:37:49.671605511Z","published":"2025-07-10T17:15:46.553Z","related":["ALSA-2025:15023","ALSA-2025:15095","ALSA-2025:15123","CGA-5j76-2vfc-pc6c","SUSE-SU-2025:02565-1","SUSE-SU-2025:02682-1","SUSE-SU-2025:02683-1","SUSE-SU-2025:02684-1","SUSE-SU-2025:02685-1","openSUSE-SU-2025:15360-1"],"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/07/10/2"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2025/07/10/8"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/08/msg00009.html"},{"type":"ADVISORY","url":"https://httpd.apache.org/security/vulnerabilities_24.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/httpd","events":[{"introduced":"69374fc08f3cda06a7acfc1cb6fe4fc0ce277f63"},{"fixed":"7e926454793abd7d71b6afc8bd1ec1648752c6ad"}],"database_specific":{"versions":[{"introduced":"2.4.35"},{"fixed":"2.4.64"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-23048.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
