Description
The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via the (1) URL value of an item or (2) user log history. To exploit the vulnerability, the attacker must be first authenticated to the application. For the first one, the attacker has to simply inject XSS code within the URL field of a shared item. For the second one however, the attacker must prepare a payload within its profile, and then ask an administrator to modify its profile. From there, whenever the administrator accesses the log, it can be XSS'ed. 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.
