Details
Summary
CVE-2023-43644 is a critical cyber vulnerability affecting Sing-box, an open source proxy system. The vulnerability allows for an authentication bypass when specially crafted requests are sent to sing-box, impacting all SOCKS5 inbounds with user authentication. This means that an attacker could potentially bypass authentication and gain unauthorized access. To remediate this vulnerability, users are advised to update to sing-box version 1.4.4 or 1.5.0-rc.4. If updating is not possible, it is recommended to avoid exposing the SOCKS5 inbound to insecure environments. The potential danger of this vulnerability lies in the fact that unauthorized individuals could gain access to sensitive information or systems within an organization, leading to data breaches and other malicious activities.
