SSL Certificate Signed using Weak Hashing Algorithm

Troubleshooting

Problem

Nessus scanner reports an issue: The SSL certificate has been signed using a weak hash algorithm.

Symptom

Issue:
SSL Certificate Signed using Weak Hashing Algorithm

Synopsis :

The SSL certificate has been signed using a weak hash algorithm.

Description :

The remote service uses an SSL certificate that has been signed using a cryptographically weak hashing algorithm - MD2, MD4, or MD5. These signature algorithms are known to be vulnerable to collision attacks.
In theory, a determined attacker may be able to leverage this weakness to generate another certificate with the same digital signature, which could allow him to masquerade as the affected service.
