Description

The vulnerability allows a remote non-authenticated attacker to manipulate data.

The checkHTTP function in libraries/Config.class.php in phpMyAdmin 4.5.x before 4.5.5.1 does not verify X.509 certificates from api.github.com SSL servers, which allows man-in-the-middle attackers to spoof these servers and obtain sensitive information via a crafted certificate.

Mitigation
Install update from vendor's website.

phpMyAdmin: 4.5.0 - 4.5.5
