  - A cross-site scripting vulnerability exists in the

  - A cross-site scripting vulnerability exists in the 'div'
    parameter of the 'graphexplorer/visApi.php' script.

    vulnerabilities.

An attacker can leverage these issues by enticing a user to follow a
malicious URL, causing attacker-specified script code to run inside
the user's browser in the context of the affected site.  Information
harvested this way may aid in launching further attacks.");
