Description Josh Bressers 2005-07-01 13:36:10 UTC
When using apache as a proxy, it is vulnerable to request smuggling.

(taken from bugtraq)

> "We describe a new web entity attack technique � �HTTP Request
> Smuggling�. The attack technique and the derived attacks are relevant
> to most web environments and is the result of a HTTP server or
> device�s failure to properly handle malformed inbound HTTP requests.
> HTTP Request Smuggling works by taking advantage of the discrepancies
> in parsing when one or more HTTP devices/entities (e.g. Cache Server,
> Proxy Server, Web Application Firewall, etc.) are in the data flow
> between the user and the web server. HTTP Request Smuggling enables
> various attacks � web cache poisoning, session hijacking, cross-site
> scripting and most serious the ability to bypass web application
> firewall protection.
