Doc Text:
A flaw was found in the webrick toolkit. This issue occurs because the server incorrectly handles requests with both Content-Length and Transfer-Encoding headers. This can allow an attacker to sneak in an extra request such as GET /admin after the normal request POST /user. As a result, unauthorized users can access restricted areas like /admin by POST /user.

Description OSIDB Bzimport 2024-09-22 01:20:36 UTC 
An issue was discovered in the WEBrick toolkit through 1.8.1 for Ruby. It allows HTTP request smuggling by providing both a Content-Length header and a Transfer-Encoding header, e.g., "GET /admin HTTP/1.1\r\n" inside of a "POST /user HTTP/1.1\r\n" request. NOTE: the supplier's position is "Webrick should not be used in production."
