Description

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.

Affected configurations

• apache http server 2.4.0 • apache http server 2.4.1 • apache http server 2.4.2 • apache http server 2.4.3 • apache http server 2.4.6 • apache http server 2.4.7 • apache http server 2.4.8 • apache http server 2.4.9 • apache http server 2.4.10 • apache http server 2.4.12 • apache http server 2.4.14 • apache http server 2.4.16 • apache http server 2.4.19 • apache http server 2.4.20 • apache http server 2.4.21 • apache http server 2.4.22 • apache http server 2.4.23
