Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: FUXA v1.1.13 suffers from **Remote Code Execution (RCE)** via the `/api/runscript` endpoint.โฆ
๐ก๏ธ **Root Cause**: **Command Injection** due to lack of input sanitization. ๐ **Flaw**: The `code` parameter in POST requests is passed directly to Node.js `child_process.exec()` without validation.โฆ
๐ข **Affected**: FUXA (Open-source SCADA/HMI/Dashboard software). ๐ฆ **Version**: Specifically **v1.1.13**. ๐ **Component**: The scripting component exposed via the `/api/runscript` API route.
Q4What can hackers do? (Privileges/Data)
๐ป **Privileges**: Commands execute with the privileges of the **FUXA service user**. ๐ **Data**: Full read/write access to server files, ability to install backdoors, or pivot to other internal systems.โฆ
๐ **Auth Status**: **UNAUTHENTICATED**. ๐ช **Threshold**: **LOW**. Attackers do not need to log in. ๐ก **Config**: Only requires network access to the `/api/runscript` endpoint. Anyone on the network can exploit it.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฅ **Public Exploits**: **YES**. Multiple PoCs exist on GitHub (e.g., `rodolfomarianocy`, `btar1gan`). ๐ ๏ธ **Tools**: Automated scripts available (Python-based) and Nuclei templates for rapid scanning.โฆ
๐ **Self-Check**: Send a crafted POST request to `/api/runscript` with a test command in the `code` field. ๐ก **Scanning**: Use **Nuclei** with the CVE-2023-33831 template.โฆ
๐ ๏ธ **Fix**: Upgrade FUXA to a patched version (check official release notes for versions > 1.1.13). ๐ **Note**: The provided data does not specify the exact fixed version, but patching is the primary mitigation.โฆ
๐ง **Workaround**: If patching is impossible, **block external access** to the `/api/runscript` endpoint via firewall/WAF. ๐ **Restrict**: Disable the scripting feature if not needed.โฆ
๐จ **Priority**: **CRITICAL**. โก **Urgency**: **IMMEDIATE ACTION REQUIRED**. Since it is unauthenticated RCE, automated bots are likely scanning for it. Patch or isolate immediately to prevent compromise. ๐โโ๏ธ๐จ
