Q1What is this vulnerability? (Essence + Consequences)
🚨 **Essence**: A Command Injection flaw in Wavlink routers. 📉 **Consequences**: Attackers can execute arbitrary commands as **root**. The core issue is unsanitized input in the login process.
Q2Root Cause? (CWE/Flaw)
🛡️ **Root Cause**: Improper input validation. Specifically, the **"key" parameter** in a login request is not filtered. This allows malicious payloads to bypass security checks and inject system commands.…
📦 **Affected Products**:
- **Wavlink WN575A4**
- **Wavlink WN579X3**
⚠️ *Note: Other Wavlink products may also be vulnerable.*
Q4What can hackers do? (Privileges/Data)
💀 **Attacker Capabilities**:
- Execute **arbitrary commands**.
- Gain **root privileges** (full system control).
- Access sensitive device data.
- Potentially compromise the entire network.
Q5Is exploitation threshold high? (Auth/Config)
🔓 **Exploitation Threshold**: **LOW**.
- **Unauthenticated**: No login required to exploit.
- **Remote**: Can be triggered over the network.
- Simple injection via the login endpoint.
Q6Is there a public Exp? (PoC/Wild Exploitation)
🔍 **Public Exploits**: **YES**.
- PoC available via **ProjectDiscovery Nuclei** templates.
- References found on **0xlabs** and **GitHub**.
- Active testing confirmed on WN575A4 and WN579X3.
Q7How to self-check? (Features/Scanning)
🔎 **Self-Check**:
- Use **Nuclei** with the CVE-2020-13117 template.
- Scan for Wavlink devices exposing the vulnerable login API.
- Check if the "key" parameter in login requests is vulnerable to injection.
Q8Is it fixed officially? (Patch/Mitigation)
🩹 **Official Fix**: Data does not explicitly mention a specific patch version or date. However, the vulnerability is well-documented (published Feb 2021).…
🚧 **Workaround**:
- **Isolate** affected devices from the internet.
- **Disable** remote management features if possible.
- **Change** default credentials (though this doesn't fix the injection, it adds a layer).
- Moni…
🔥 **Urgency**: **CRITICAL**.
- **Unauthenticated RCE** is a high-severity threat.
- Easy to exploit with public tools.
- **Action**: Patch or isolate immediately to prevent remote takeover.
