CVE-2016-2562

Estado: ModificadaMedia (6.8)—

La función checkHTTP en libraries/Config.class.php en phpMyAdmin 4.5.x en versiones anteriores a 4.5.5.1 no verifica certificados X.509 desde los servidores SSL de api.github.com, lo que permite a atacantes man-in-the-middle suplantar estos servidores y obtener información sensible a través de un certificado manipulado.
