9.2.25.v20180606- Upgrade org.eclipse.jetty:jetty-server to this version or later
Description
Eclipse Jetty Server versions 9.2.x and older, 9.3.x (all non HTTP/1.x configurations), and 9.4.x (all HTTP/1.x configurations), are vulnerable to HTTP Request Smuggling when presented with two content-lengths headers, allowing authorization bypass. When presented with a content-length and a chunked encoding header, the content-length was ignored (as per RFC 2616). If an intermediary decides on the shorter length, but still passes on the longer body, then body content could be interpreted by Jetty as a pipelined request. If the intermediary is imposing authorization, the fake pipelined request bypasses that authorization.
Affected versions

| Package | Vulnerable | Fixed in |
|---|---|---|
| org.eclipse.jetty:jetty-server | < 9.2.25.v20180606 |
9.2.25.v20180606 |
| org.eclipse.jetty:jetty-server | >= 9.3.0, < 9.3.24.v20180605 |
9.3.24.v20180605 |
| org.eclipse.jetty:jetty-server | >= 9.4.0, < 9.4.11.v20180605 |
9.4.11.v20180605 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling')
The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination.
How to prevent it
- Implementation: Use a web server that employs a strict HTTP parsing procedure, such as Apache [REF-433].
- Implementation: Use only SSL communication.
- Implementation: Terminate the client session after each request.
- System Configuration: Turn all pages to non-cacheable.
