has a cross-site scripting vulnerability.  Input passed to the
'error' parameter of '/PerformanceManagement/jsp/viewError.jsp' is
not properly sanitized.

A remote attacker could exploit this by tricking a user into
requesting a specially crafted URL, resulting in the execution of
arbitrary script code.

This version of BusinessObjects reportedly has several other
vulnerabilities, though Nessus has not checked for those issues."
