Vulnerable: DataWatch Monarch BI v5.1

DataWatch's  Monarch BI client section is prone to a stored cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied data.

An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, steal cookie-based authentication credentials, and obtain sensitive information.

DataWatch Monarch BI v5.1 is known to be vulnerable. Other versions may also be vulnerable.

To exploit this issue, an attacker must entice an unsuspecting victim into following a malicious URI, for example:

POST http://127.0.0.1/ESClient/jsp/prefoutact.jsp 
DecimalSeparator=.');alert(2);//
