BIT-APACHE-2025-49812 Apache HTTP Server: mod_ssl TLS upgrade attack
In some modssl configurations on Apache HTTP Server versions through to 2.4.63, an HTTP desynchronisation attack allows a man-in-the-middle attacker to hijack an HTTP session via a TLS upgrade. Only configurations using "SSLEngine optional" to enable TLS upgrades are affected. Users are recommend...
BIT-APACHE-2025-23048 Apache HTTP Server: mod_ssl access control bypass with session resumption
In some modssl 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 modssl is configured for multiple virtual hosts, with each restricted to a different set of...
BIT-APACHE-2024-47252 Apache HTTP Server: mod_ssl error log variable escaping
Insufficient escaping of user-supplied data in modssl in Apache HTTP Server 2.4.63 and earlier allows an untrusted SSL/TLS client to insert escape characters into log files in some configurations. In a logging configuration where CustomLog is used with "%varnamex" or "%varnamec" to log variables...
CVE-2025-23048
An access control bypass vulnerability was found in Apache httpd. The Apache HTTP Server with some modssl configurations can bypass the access controls by trusted clients using TLS 1.3 session resumption. A client trusted to access one virtual host may be able to access another if...
