Description Jan Lieskovsky 2013-07-29 17:09:07 UTC 
A security flaw was found in the way JSON file to be retrieved version check functionality of phpMyAdmin, a tool written in PHP intended to handle the administration of MySQL over the World Wide Web, previously used to validate content of the retrieved JSON file. A remote attacker could provide a specially-crafted JSON format file that, when accepted (and processed) by the phpMyAdmin's user session would lead to arbitrary HTML or web script execution in the context of phpMyAdmin's user session.
