Description
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks via a document resource (such as pagetitle), which is mishandled during an Update action, a Quick Edit action, or the viewing of manager logs.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
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.
