extplorer: cross-site request forgery

John Leitch has discovered a vulnerability in eXtplorer, a very feature rich web server file manager, which can be exploited by malicious people to conduct cross-site request forgery attacks.

The vulnerability allows users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited for example, to create an administrative user account by tricking an logged administrator to visiting an attacker-defined web link.
