- Summary
- HTTP Request Smuggling in Waitress: Invalid whitespace characters in headers (Follow-up)
- Details
-
Impact
The patches introduced to fix https://github.com/Pylons/waitress/security/advisories/GHSA-m5ff-3wj3-8ph4 were not complete and still would allow an attacker to smuggle requests/split a HTTP request with invalid data.
This updates the existing CVE with ID: CVE-2019-16789
Patches
Waitress version 1.4.2 has been updated to now validate HTTP headers better to avoid the issue, completely fixing all known issues with whitespace.
Workarounds
There are no work-arounds, upgrading to Waitress 1.4.2 is highly recommended.
