How to fix?

Upgrade RHEL:9 mod_ldap to version 0:2.4.57-11.el9_4.3 or higher.
This issue was patched in RHSA-2025:14903.

NVD Description

Note: Versions mentioned in the description apply only to the upstream mod_ldap package and not the mod_ldap package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

Insufficient escaping of user-supplied data in mod_ssl 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 "%{varname}x" or "%{varname}c" to log variables provided by mod_ssl such as SSL_TLS_SNI, no escaping is performed by either mod_log_config or mod_ssl and unsanitized data provided by the client may appear in log files.
