Cross-Site Scripting (XSS) in qTranslate WordPress Plugin

High-Tech Bridge Security Research Lab discovered vulnerability in qTranslate WordPress plugin, which can be exploited to perform Cross-Site Scripting (XSS) attacks against website administrators. Successful exploitation of this vulnerability may allow a remote attacker to gain complete control over the web application, if the victim visits a malicious page with XSS exploit. This vulnerability can also be used to perform drive-by-download or phishing attacks against website administrators.

Input passed via “edit” HTTP GET parameter to “/wp-admin/options-general.php” is not properly sanitised before being returned to the user. A remote attacker can trick a logged-in administrator to open a specially crafted link and execute arbitrary HTML and script code in browser in context of the vulnerable website.

A simple exploit below will display a JS popup with “ImmuniWeb” word:
