The SSLv3 POODLE vulnerability, disclosed on October 14, 2014, is a protocol-level security flaw affecting the SSL 3.0 encryption standard. POODLE, which stands for Padding Oracle On Downgraded Legacy Encryption, exploits weaknesses in how SSLv3 handles padding during encryption. This vulnerability arises when plaintext is converted into ciphertext. To match cryptographic requirements, extra padding is added, and during decryption, this padding can leak sensitive information. Attackers can take advantage of this flaw through a man-in-the-middle (MITM) attack, gradually decrypting secure communications. How to Check if Your WHM/cPanel Server is Vulnerable To verify whether SSLv3 is enabled on your server, log in via SSH as the root user and run the following command: Example: A typical secure response will show: Advanced …
