CVE-2026-43947— frangoteam FUXA 授权问题漏洞

FUXA Vulnerable to Unauthenticated Remote Code Execution via Script Test Mode Authorization Bypass

FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. Version 1.3.0 has an unauthenticated Remote Code Execution vulnerability when `secureEnabled` is set to `true`. The `POST /api/runscript` endpoint checks authorization against the stored script's permission by ID, but when `test: true` is set in the request, it compiles and executes attacker-supplied code instead of the stored script's code. An unauthenticated attacker who knows a valid script ID and name may execute arbitrary code via test mode if at least one server-side script exists and is accessible without restrictive permissions. Script IDs and names can be obtained through the unauthenticated information disclosure in `GET /api/project` (reported separately). The only prerequisite is that at least one server-side script exists in the project. Version 1.3.1 fixes the issue.

授权机制不正确

frangoteam FUXA 授权问题漏洞

frangoteam FUXA是frangoteam团队开源的一个基于web的过程可视化软件。 frangoteam FUXA 1.3.0版本存在授权问题漏洞，该漏洞源于在POST /api/runscript端点授权检查不当，当请求设置test: true时，会编译并执行攻击者提供的代码而非存储脚本的代码，可能导致未经身份验证的攻击者知晓有效脚本ID和名称后通过测试模式执行任意代码。
