Summary
Eventlet affected by HTTP request smuggling in unparsed trailers
Details

Impact

The Eventlet WSGI parser is vulnerable to HTTP Request Smuggling due to improper handling of HTTP trailer sections.

This vulnerability could enable attackers to: - Bypass front-end security controls - Launch targeted attacks against active site users - Poison web caches

Patches

Problem has been patched in eventlet 0.40.3.

The patch just drops trailers. If a backend behind eventlet.wsgi proxy requires trailers, then this patch BREAKS your setup.

Workarounds

Do not use eventlet.wsgi facing untrusted clients.
