EUVDB-ID: #VU26356

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-10109

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform HTTP request smuggling attack.

The vulnerability exists due to insufficient input validation when processing Content-length and a Chunked encoding header, sent within one HTTP request. The Content-length header took precedence and the remainder of the request body was interpreted as a pipelined request. A remote attacker can send a specially crafted HTTP request to the affected web server and poison HTTP cache or perform other attacks against web application.

Mitigation

Update the affected package python-Twisted to the latest version.
