{"id":"CVE-2025-23048","summary":"Apache HTTP Server: mod_ssl access control bypass with session resumption","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":"2026-05-18T05:57:25.417879640Z","published":"2025-07-10T16:56:53.545Z","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"],"database_specific":{"cna_assigner":"apache","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/23xxx/CVE-2025-23048.json","cwe_ids":["CWE-284"],"unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"2.4.35"},{"last_affected":"2.4.63"}]},{"source":"DESCRIPTION","extracted_events":[{"introduced":"2.4.35"}]}]},"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://github.com/CVEProject/cvelistV5/tree/main/cves/2025/23xxx/CVE-2025-23048.json"},{"type":"ADVISORY","url":"https://httpd.apache.org/security/vulnerabilities_24.html"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-23048"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/httpd","events":[{"introduced":"69374fc08f3cda06a7acfc1cb6fe4fc0ce277f63"},{"fixed":"7e926454793abd7d71b6afc8bd1ec1648752c6ad"}],"database_specific":{"source":"CPE_FIELD","extracted_events":[{"introduced":"2.4.35"},{"fixed":"2.4.64"}],"cpe":"cpe:2.3:a:apache:http_server:*:*:*:*:*:*:*:*"}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-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"}]}
