CVE-2016-0736

httpd: Padding Oracle in Apache mod_session_crypto

Published Jul 27, 2017 CVSS 3.0 · 7.5 High EPSS 49.0% KEV · Not listed
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.
