OVERVIEW

        Two vulnerabilities identified in Hitachi Web server have been
        corrected by the vendor.


IMPACT

        A cross site scripting vulnerability can be exploited when a Hitachi
        Web Server automatically creates a server status page in response to
        a request containing malicious scripts, potentially allowing for 
        those scripts to be executed on a client. [1]
        
        An invalid response from a remote backend server may cause a Hitachi
        Web Server to experience a denial of service if the system uses the
        reverse proxy function. [2]


MITIGATION

        The vendor recommends upgrading to the appropriate version. [1, 2]
