Ubuntu Security Notice 7057-2 - USN-7057-1 fixed a vulnerability in WEBrick. This update provides the corresponding updates for Ubuntu 22.04 LTS. It was discovered that WEBrick incorrectly handled having both a Content- Length header and a Transfer-Encoding header. A remote attacker could possibly use this issue to perform a HTTP request smuggling attack.
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."
