Drupal CiviCRM Module SSL Certificate Validation Security Bypass Vulnerability


CiviCRM module for Drupal is prone to a security-bypass vulnerability because the application fails to properly validate SSL certificates from a server.



Vulnerable Systems:
 * Drupal

CiviCRM 4.0.5 and 4.1.1 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.
