It allows you to create web applications with Apache2, PHP and a MySQL database. Alongside, PhpMyAdmin allows you to manage easily your databases." Official website: http://www.wampserver.com/en/ Vulnerability description: The add_vhost.php script in the administration panel of Wampserver was vulnerable to Cross Site Request Forgery (CVE-2018-8817 - https://www.exploit-db.com/exploits/44385) in WampServer 3.1.2 and below. The synchronizer pattern added as remediation was not implemented properly, so that WampServer 3.1.3 - 3.1.8 were still vulnerable to CSRF; attackers could abuse this flaw to get new vhosts added or existing ones deleted in the Apache configuration file. Technical requirement of successful exploitation is that the admin has not opened the add_vhost.php file in the current browser serssion yet (so the random tokens are not initialized).
