Detailsinfo

A vulnerability was found in Apache HTTP Server up to 2.4.63. It has been classified as critical. Affected is some unknown processing of the component mod_ssl. The manipulation with an unknown input leads to a access control vulnerability. CWE is classifying the issue as CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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. Configurations 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.

The weakness was shared by Sven Hebrok, Felix Cramer, Tim Storm, Maximilian Radoy and Juraj Somorovsky. The advisory is available at httpd.apache.org. This vulnerability is traded as CVE-2025-23048 since 01/10/2025. The exploitability is told to be easy. It is possible to launch the attack remotely.
