SSL Certificate Null Character Spoofing Weakness

Synopsis :

This plugin determines if the remote SSL certificate contains a Null

Description :

The remote host contains an SSL certificate with a common name
containing a Null character (\x00) in it. This may indicate a
compromise or that a program such as SSLsniff is spoofing the
certificate in order to intercept the traffic via a Man-in-The-Middle
(MiTM) attack.

Certificates with such characters may exploit a bug contained in many
different web browser and other SSL-related products, in how they
validate the common name of such a certificate.
