CVE-2016-0736
HIGH7.5EPSS 41.7%apache2 - security update
Published: 7/27/2017Modified: 4/28/2026
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 packages (2)
- Debian/apache2from 0, < 2.4.25-1
- Debian/apache2from 0, < 2.4.10-10+deb8u8
