Cisco Talos recently discovered multiple vulnerabilities in the phpGACL class. One of these vulnerabilities also affects OpenEMR, a medical practice management software written in PHP. phpGACL is a PHP library that allows developers to implement permission systems via a Generic Access Control List. An adversary could exploit these vulnerabilities by sending the target machine a specially crafted, malicious HTTP request or URL.In accordance with our coordinated disclosure policy, Cisco Talos worked with phpGACL and OpenEMR to ensure that these issues are resolved and that an update is available for affected customers.
