Synopsis

Gunicorn < 19.10.0 HTTP Request Smuggling

Description

According to its self-reported version number, the version of Gunicorn installed on the remote host is prior to 19.10.0 or 20.0.x prior to 20.0.1. It is, therefore, affected by a HTTP request smuggling vulnerability when processing a malicious transfer-encoding header. Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Gunicorn version 19.10.0 or later.
