{"id":"BIT-apache-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":["CVE-2025-23048"],"modified":"2025-11-06T13:25:46.476Z","published":"2025-07-16T07:56:19.860Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:apache:http_server:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://httpd.apache.org/security/vulnerabilities_24.html"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-23048"},{"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"}],"affected":[{"package":{"name":"apache","ecosystem":"Bitnami","purl":"pkg:bitnami/apache"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.4.35"},{"fixed":"2.4.64"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/apache/BIT-apache-2025-23048.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}],"schema_version":"1.7.3"}
