Description

The Jakarta Commons HttpClient component can be used to build HTTP-aware
client applications (such as web browsers and web service clients).

The Jakarta Commons HttpClient component did not verify that the server
hostname matched the domain name in the subject's Common Name (CN) or
subjectAltName field in X.509 certificates. This could allow a
man-in-the-middle attacker to spoof an SSL server if they had a certificate
that was valid for any domain name. (CVE-2012-5783)
