Web Server Expect Header XSS

medium Nessus Plugin ID 22254

Language:

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.

Solution

Check with the vendor for an update to the web server. For Apache, the issue is reportedly fixed by versions 1.3.35 / 2.0.57 / 2.2.2; for IBM HTTP Server, upgrade to 6.0.2.13 / 6.1.0.1; for IBM WebSphere Application Server, upgrade to 5.1.1.17.
