CVE-2016-9834


Details:

=======

This vulnerability allows remote attackers to execute arbitrary client side
script in the active user’s browser session, when logged into the Cyberoam
firewall. User interaction is required to exploit this vulnerability in
that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the handling of request to
“LiveConnectionDetail.jsp” application. GET parameters “applicationname”
and “username” are improperly sanitized allowing an attacker to inject
arbitrary javascript into the page. This can be abused by an attacker to
perform a cross-site scripting attack on the user.
