A Reflected Cross-Site Scripting vulnerability exists in the Huge IT Portfolio Gallery WordPress plugin. This vulnerability allows an attacker to perform any action with the privileges of the admin user. The affected code is not protected with an anti-Cross-Site Request Forgery token. Consequently, it can be exploited by luring the target user into clicking a specially crafted link or visiting a malicious website (or advertisement).

The vulnerability exists in the file .portfolio-gallery/admin/portfolios_views.php (line 804):

<a href="admin.php?page=portfolios_huge_it_portfolio&task=portfolio_video&id=<?php echo $_GET['id']; ?>&TB_iframe=1"
class="button button-primary add-video-slide thickbox" id="slideup3s" value="iframepop">

The vulnerability can be exploited using a specially crafted ajaxurl URL parameter. In order to exploit this issue the target user must click a specially crafted link or visit a malicious website (or advertisement).
