What is CVE-2016-2183?

The vulnerability occurs due to the use of the DES and Triple DES ciphers within TLS, SSH, and IPSec protocols. These ciphers are subject to a birthday attack, which can potentially allow attackers to extract plaintext data from long-lived encrypted sessions. The risk is particularly evident during HTTPS connections employing Triple DES in CBC mode, commonly known as the 'Sweet32' attack. This vulnerability emphasizes the need for transitioning to more secure encryption standards in order to protect sensitive data.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
