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 "jql" HTTP GET parameter to "/rest/gadget/1.0/issueTable/jql" URL. 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.
Exploitation example:
http://[host]/rest/gadget/1.0/issueTable/jql?jql=XSS
