Incorrect access control in the install directory (C:\Wamp64) of Wamp v3.2.6 and below allows authenticated attackers to execute arbitrary code via overwriting binaries located in the directory.
WampServer before 3.1.9 has CSRF in add_vhost.php because the synchronizer pattern implemented as remediation of CVE-2018-8817 was incomplete. An attacker could add/delete any vhosts without the consent of the owner.
Wampserver version prior to version 3.1.5 contains a Cross Site Scripting (XSS) vulnerability in index.php localhost page that can result in very low. This attack appear to be exploitable via payload onmouseover. This vulnerability appears to have been fixed in 3.1.5 and later.
