Hiawatha Webserver Request Smuggling Vulnerability

A request smuggling vulnerability has been identified in Hiawatha Webserver version 11.7. This issue arises from improper header parsing, which may allow an unauthenticated attacker to access restricted resources managed by the webserver.

Impact

Exploitation of this vulnerability could lead to unauthorized access to restricted resources on the server.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request that takes advantage of the server's improper header parsing. This can be done by manipulating the 'Content-Length' or 'Transfer-Encoding' headers to create a smuggling effect, where one part of the request is processed differently than intended, potentially allowing access to restricted resources.
