Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU83631

Risk: Medium

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-47627

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 attacks.

The vulnerability exists due to improper validation of HTTP requests when AIOHTTP_NO_EXTENSIONS is enabled. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
