CVE-2024-43798— Chisel 安全漏洞

Chisel AUTH environment variable not respected in server entrypoint

Chisel is a fast TCP/UDP tunnel, transported over HTTP, secured via SSH. The Chisel server doesn't ever read the documented `AUTH` environment variable used to set credentials, which allows any unauthenticated user to connect, even if credentials were set. Anyone running the Chisel server that is using the `AUTH` environment variable to specify credentials to authenticate against is affected by this vulnerability. Chisel is often used to provide an entrypoint to a private network, which means services that are gated by Chisel may be affected. Additionally, Chisel is often used for exposing services to the internet. An attacker could MITM requests by connecting to a Chisel server and requesting to forward traffic from a remote port. This issue has been addressed in release version 1.10.0. All users are advised to upgrade. There are no known workarounds for this vulnerability.

关键功能的认证机制缺失

Chisel 安全漏洞

Chisel是Jaime Pillora个人开发者的一个快速的 TCP/UDP 隧道。 Chisel v1.10.0之前版本存在安全漏洞，该漏洞源于服务器未读取用于设置认证凭据的AUTH环境变量，这可能导致任何未经身份验证的用户都能够连接到Chisel服务器，即便已设置了凭据。
