WebApr 2, 2024 · Share. Browser Exploit Against SSL/TLS (BEAST) is an attack that exploits a vulnerability in the Transport-Layer Security (TLS) 1.0 and older SSL protocols, using the cipher block chaining (CBC) mode encryption. It allows attackers to capture and decrypt HTTPS client-server sessions and obtain authentication tokens. WebDROWN allows attackers to break the encryption and read or steal sensitive communications, including passwords, credit card numbers, trade secrets, or financial data. A server is vulnerable to DROWN if: It allows SSLv2 connections OR. Its private key is used on any other server that allows SSLv2 connections, even for another protocol.
