### [CVE-2016-0736](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-0736) ![](https://img.shields.io/static/v1?label=Product&message=Apache%20HTTP%20Server&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Vulnerability&message=Padding%20Oracle%20Attack&color=brighgreen) ### 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. ### POC #### Reference - https://www.exploit-db.com/exploits/40961/ #### Github - https://github.com/ARPSyndicate/cvemon - https://github.com/firatesatoglu/shodanSearch - https://github.com/vshaliii/DC-2-Vulnhub-Walkthrough
