CVEID:_CVE-_2012-6153

DESCRIPTION: Apache HttpComponents could allow a remote attacker to conduct spoofing attacks, caused by an incomplete fix related to the failure to verify that the server hostname matches a domain name in the Subject’s Common Name (CN) or SubjectAltName field of certificates. 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.
CVSS Base Score: 4.3
