Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Command Injection in RaspAP. π **Consequences**: Attackers can execute **arbitrary commands** on the target system. This leads to full system compromise, data theft, or lateral movement.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **Command Injection** via the `cfg_id` parameter. π **Flaw**: The application fails to sanitize user input in `/ajax/openvpn/activate_ovpncfg.php` and `/ajax/openvpn/del_ovpncfg.php` endpoints.
π **Privileges**: **Unauthenticated** attackers gain access. ποΈ **Data**: Can execute **any command** with the privileges of the web server process. This means full control over the device.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **LOW**. π« **Auth**: No authentication required. π‘ **Config**: Direct access to the API endpoints is sufficient. Anyone on the network can exploit this.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Public Exp**: **YES**. π **PoCs**: Multiple Python and Bash scripts available on GitHub (e.g., `RaspAP-CVE-2022-39986-PoC`, `RaspAP Hunter`). π **Wild Exp**: Active scanning tools like Nuclei have templates.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Use `RaspAP Hunter` bash script or Nuclei templates. π‘ **Scan**: Look for RaspAP installations on port 80/443. π§ͺ **Test**: Send malicious `cfg_id` payload to `/ajax/openvpn/activate_ovpncfg.php`.
Q8Is it fixed officially? (Patch/Mitigation)
π οΈ **Fix**: Upgrade to a version **later than 2.8.7**. π **Patch**: The vendor released updates addressing the input validation flaw in the OpenVPN configuration endpoints.
Q9What if no patch? (Workaround)
π§ **Workaround**: If patching is impossible, **block external access** to the RaspAP web interface. π« **Restrict**: Use firewall rules to allow only trusted IPs.β¦
π₯ **Urgency**: **CRITICAL**. π¨ **Priority**: **P1**. β‘ **Reason**: Unauthenticated RCE with public exploits. Immediate patching or mitigation is required to prevent immediate compromise.
