What is SSL Lucky13 Vulnerability?
SSL Lucky13 is a cryptographic timing attack that targets the CBC (Cipher Block Chaining) mode in SSL/TLS protocols. The vulnerability exploits small timing discrepancies during decryption, allowing attackers to recover plaintext data from encrypted communications.
The attack is called "Lucky13" because it exploits the padding structure used in CBC mode, specifically the 13-byte header processed during decryption. By carefully analyzing response times for malformed requests, attackers can infer sensitive information such as authentication tokens or session data. This vulnerability primarily affects TLS 1.0 and 1.1 but can also pose a risk in improperly implemented TLS 1.2 systems.
Mitigation strategies include adopting modern encryption protocols like TLS 1.3, ensuring constant-time cryptographic operations, and disabling CBC-mode cipher suites where feasible.
