Expect Header Cross-Site Scripting Vulnerability Vulnerability Scan


Vulnerability Scan Summary
Checks for an XSS flaw involving Expect Headers

Detailed Explanation for this Vulnerability Test

Synopsis :

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'
request header before using it to generate dynamic web content. An
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.
