Description
The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'regurl' attribute of the [wpdm_login_form] shortcode in all versions up to, and including, 3.3.71. This is due to the attribute value being printed into the href of the form's 'Sign up' link with only esc_attr(), which does not remove javascript: URLs. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute when a visitor clicks the injected link.
