CVE-2024-1135

Gunicorn fails to properly validate Transfer-Encoding headers, leading to HTTP Request Smuggling (HRS) vulnerabilities. By crafting requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue is due to Gunicorn's handling of Transfer-Encoding headers, where it incorrectly processes requests with multiple, conflicting Transfer-Encoding headers, treating them as chunked regardless of the final encoding specified. This vulnerability has been shown to allow access to endpoints restricted by gunicorn. This issue has been addressed in version 22.0.0.

To be affected users must have a network path which does not filter out invalid requests. These users are advised to block access to restricted endpoints via a firewall or other mechanism if they are unable to update.

Release Notes

benoitc/gunicorn (gunicorn)

v22.0.0: Gunicorn 22.0 has been released

Compare Source

Gunicorn 22.0.0 has been released. This version fix the numerous security vulnerabilities. You're invited to upgrade asap your own installation.

Changes:

22.0.0 - 2024-04-17
===================

- use `utime` to notify workers liveness
- migrate setup to pyproject.toml
- fix numerous security vulnerabilities in HTTP parser (closing some request smuggling vectors)
- parsing additional requests is no longer attempted past unsupported request framing
- on HTTP versions < 1.1 support for chunked transfer is refused (only used in exploits)
- requests conflicting configured or passed SCRIPT_NAME now produce a verbose error
- Trailer fields are no longer inspected for headers indicating secure scheme
- support Python 3.12

** Breaking changes **

- minimum version is Python 3.7
- the limitations on valid characters in the HTTP method have been bounded to Internet Standards
- requests specifying unsupported transfer coding (order) are refused by default (rare)
- HTTP methods are no longer casefolded by default (IANA method registry contains none affected)
- HTTP methods containing the number sign (#) are no longer accepted by default (rare)
- HTTP versions < 1.0 or >= 2.0 are no longer accepted by default (rare, only HTTP/1.1 is supported)
- HTTP versions consisting of multiple digits or containing a prefix/suffix are no longer accepted
- HTTP header field names Gunicorn cannot safely map to variables are silently dropped, as in other software
- HTTP headers with empty field name are refused by default (no legitimate use cases, used in exploits)
- requests with both Transfer-Encoding and Content-Length are refused by default (such a message might indicate an attempt to perform request smuggling)
- empty transfer codings are no longer permitted (reportedly seen with really old & broken proxies)
