NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd package and not the httpd package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In Apache HTTP Server versions 2.4.0 to 2.4.23, mod_session_crypto was encrypting its data/cookie using the configured ciphers with possibly either CBC or ECB modes of operation (AES256-CBC by default), hence no selectable or builtin authenticated encryption. This made it vulnerable to padding oracle attacks, particularly with CBC.
