CVE-2013-2037 is a vulnerability of currently unknown severity. httplib2 0.7.2, 0.8, and earlier, after an initial connection is made, 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.. EPSS estimates a 1.32% chance of exploitation in the next 30 days.
