Ssl Tls Server Accepts Tlsv1 1 Connections

Description

Detects if a web server accepts TLS 1.1 connections, which is a deprecated and insecure protocol version. TLS 1.1 contains known cryptographic weaknesses and has been officially deprecated since March 2021, making systems that support it vulnerable to downgrade attacks and other security issues.

Weakness:

016 - Insecure encryption algorithm - SSL/TLS

Category: Information Collection

Detection Strategy

    Attempts to establish a TLS 1.1 connection to the target server

    Reports a vulnerability if the server successfully negotiates and accepts a TLS 1.1 connection

    Checks the server's response regardless of which cipher suite is used for the connection
