Ssl Tls Certificate Weak Signature Md5

Description

This detector identifies SSL/TLS certificates that use the weak MD5 hash algorithm for digital signatures. MD5 is cryptographically broken and vulnerable to collision attacks, making certificates signed with MD5 unsuitable for secure communications and potentially allowing attackers to forge certificates.

Weakness:

263 - Insecure encryption algorithm - MD5

Category: Information Collection

Detection Strategy

    Establishes an SSL/TLS connection to the target server

    Retrieves the server's X.509 certificate

    Examines the signature hash algorithm used to sign the certificate

    Reports a vulnerability when the certificate is signed using the MD5 hash algorithm
