GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

CVE-2016-0736 (GCVE-0-2016-0736)

Vulnerability from cvelistv5 – Published: 2017-07-27 21:00 – Updated: 2024-09-16 17:52
VLAI
Summary
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.
CWE
  • Padding Oracle Attack
