CVE-2023-43644 (GCVE-0-2023-43644)

Vulnerability from cvelistv5 – Published: 2023-09-25 19:12 – Updated: 2024-09-24 19:29

Title

Improper authentication in the SOCKS5 inbound in sing-box

Summary

Sing-box is an open source proxy system. Affected versions are subject to an authentication bypass when specially crafted requests are sent to sing-box. This affects all SOCKS5 inbounds with user authentication and an attacker may be able to bypass authentication. Users are advised to update to sing-box 1.4.4 or to 1.5.0-rc.4. Users unable to update should not expose the SOCKS5 inbound to insecure environments.

Severity
