Vulnerability Details
CVEID: CVE-2012-5783
DESCRIPTION: Apache Commons HttpClient, as used in Amazon Flexible Payments
Service (FPS) merchant Java SDK and other products, could allow a remote
attacker to conduct spoofing attacks, caused by the failure to verify that the
server hostname matches a domain name in the subject's Common Name (CN) field
of the X.509 certificate. By persuading a victim to visit a Web site
containing a specially-crafted certificate, an attacker could exploit this
vulnerability using man-in-the-middle techniques to spoof an SSL server.
