IBM Tivoli Directory Server TLS NULL Cipher (uncredentialed check)

This script is Copyright (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote IBM Tivoli Directory Server contains an information
disclosure vulnerability.

Description :

The IBM Tivoli Directory Server hosted on the remote host supports TLS
NULL-MD5 or NULL_SHA ciphers. This allows remote, unauthenticated
attackers to trigger unencrypted communication via the TLS handshake
protocol.

Note that this version of Directory Server likely has other
vulnerabilities (i.e., CVE-2012-0743), but Nessus has not checked
for those issues.
