Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server is vulnerable to a cross-site scripting attack.

Description :

The remote web server fails to sanitize the contents of an 'Expect'

unauthenticated remote attacker may be able to leverage this issue to
launch cross-site scripting attacks against the affected service,
perhaps through specially-crafted ShockWave (SWF) files.
