Description
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied JSON data. A remote authenticated user with "manipulate queues" privileges can inject specially crafted data and execute arbitrary HTML and script code on a page where nodequeue.js is loaded.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
