Using insecure and deprecated protocols can make connections vulnerable to exploits such as DROWN (Decrypting RSA using Obsolete and Weakened eNcryption), which targets a specific weakness in the OpenSSL implementation of SSLv2 protocol, and POODLE (Padding Oracle On Downgraded Legacy Encryption). This vulnerability allows an attacker to read information encrypted with SSLv3 protocol in plain text, using a person-in-the-middle or an eavesdropping attack.
