CVE-2012-5456 is a vulnerability of currently unknown severity. The Zoner AntiVirus Free application for Android does not verify that the server hostname matches a domain name in the subject's Common Name (CN) field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate, as demonstrated by a server used for updating virus signature files.. EPSS estimates a 0.99% chance of exploitation in the next 30 days.
