Bug Description :
The ISM consists of device management software, cloud storage management 
software, and storage network management software. The device management 
software, downloaded over JWS or installed through a CD-ROM, is applies to the 
management of Huawei Symantec storage devices, the cloud storage management 
software applies to the management of Huawei Symantec storage devices and 
resources and the storage network management software applies to the management 
of Huawei Symantec SAN storage devices. The cloud storage management software 
and storage network management software are deployed on independent servers and 
users can access the software through browsers.
ISM Professional (ver Huawei Technologies Co., Ltd. 2009-2010.) The server 
reads data directly from the HTTP request and reflects it back in the HTTP 
response. Reflected XSS exploits occur when an attacker causes a victim to 
supply dangerous content to a vulnerable web application, which is then 
reflected back to the victim and executed by the web browser. The most common 
mechanism for delivering malicious content is to include it as a parameter in a 
URL that is posted publicly or e-mailed directly to the victim. URLs 
constructed in this manner constitute the core of many phishing schemes, 
whereby an attacker convinces a victim to visit a URL that refers to a 
vulnerable site. After the site reflects the attacker's content back to the 
victim, the content is executed by the victim's browser.
