CVE-2012-5814

Estado: ModificadaMedia (5.8)—

Weberknecht, as used in GitHub Gaug.es and other products, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
