High

Base vector

AV:N/AC:L/Au:N/C:N/I:C/A:N

Name of the Vulnerable Software and Affected Versions: Apache HTTP Server versions prior to 2.4.63

Description: Insufficient escaping of user-supplied data in the mod ssl module can allow an untrusted SSL/TLS client to insert escape characters into log files under certain configurations. This occurs when using CustomLog with "%{varname}x" or "%{varname}c" to log variables provided by mod ssl, such as SSL TLS SNI, without proper sanitization.

Recommendations: Upgrade to a version of Apache HTTP Server later than 2.4.63.
