Subject: [FD] Reflected XSS in WordPress Download Manager could allow an
	attacker to do almost anything an admin can (WordPress plugin)

Software: WordPress Download Manager
Version: 2.9.46,2.9.51
Advisory report:
CVE: Awaiting assignment
CVSS: 5.8 (Medium; AV:N/AC:M/Au:N/C:P/I:P/A:N)

Reflected XSS in WordPress Download Manager could allow an attacker to do almost anything an admin can

This plugin outputs $_GET[‘id’] inside HTML without escaping, meaning that anybody able to convince an admin to follow a link can add arbitrary HTML to the page.

Proof of concept

Sign in
Activate the plugin
Visit the following URL in a browser without XSS mitigation (i.e. Firefox): http://localhost/wp-admin/admin-ajax.php?action=wpdm_generate_password&id=%3C/script%3E%3Cscript%3Ealert(1)%3C/script%3E

Upgrade to version 2.9.52 or later.
