Exploitation Summary
EIP tracks 2 public exploits for CVE-2023-40167. PoCs published by ifrenkel, uthrasri.
AI-analyzed exploit summary The repository contains a minimal Java Maven project with placeholder code for security testing but lacks functional exploit code for CVE-2023-40167. It includes CI configurations and insecure coding practices for SAST/dependency scanning tests.
Description
Jetty is a Java based web server and servlet engine. Prior to versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1, Jetty accepts the `+` character proceeding the content-length value in a HTTP/1 header field. This is more permissive than allowed by the RFC and other servers routinely reject such requests with 400 responses. There is no known exploit scenario, but it is conceivable that request smuggling could result if jetty is used in combination with a server that does not close the connection after sending such a 400 response. Versions 9.4.52, 10.0.16, 11.0.16, and 12.0.1 contain a patch for this issue. There is no workaround as there is no known exploit scenario.
