Apache Axis2 1.6.2 and earlier versions do not verify that the server hostname matches a domain name in the subject's Common Name (CN) or Subject Alternative Name (subjectAltName) field of the X.509 certificate.
Apache Axis2 1.6.2 uses commons-httpclient-3.1.0 and host name verification should be enabled in the commons-httpclient.
This allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
