Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A critical OS Command Injection flaw in RaspAP. π **Consequences**: Attackers can execute arbitrary system commands, leading to total device compromise.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Improper input validation. The `iface` parameter in `/ajax/networking/get_netcfg.php` fails to filter special characters like `;`. π₯ **Flaw**: Direct command execution without sanitization.
π **Privileges**: Arbitrary OS command execution. π **Data**: Full control over the underlying OS. Attackers can read, modify, or delete any data accessible to the service.
Q5Is exploitation threshold high? (Auth/Config)
β οΈ **Threshold**: **LOW**. Exploitation is **unauthenticated**. π **Config**: No login required. Attackers just need network access to send a crafted GET request with the malicious `iface` parameter.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp**: **YES**. Proof-of-Concept (PoC) available via Nuclei templates and GitHub gists. π **Wild Exploitation**: High risk due to simplicity of the GET request vector.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for RaspAP instances. π§ͺ **Test**: Send a GET request to `/ajax/networking/get_netcfg.php?iface=test;id` and check for command output in the response. π‘ **Tools**: Use Nuclei or Burp Suite.
Q8Is it fixed officially? (Patch/Mitigation)
π οΈ **Official Fix**: Yes, update to a version **> 2.6.5**. π₯ **Action**: Check the official RaspAP repository for the latest stable release which includes input sanitization fixes.
Q9What if no patch? (Workaround)
π§ **Workaround**: If patching isn't possible, **restrict network access** to the RaspAP interface. π« **Block**: Use firewall rules to deny external access to `/ajax/networking/` endpoints.β¦
π₯ **Urgency**: **CRITICAL**. π¨ **Priority**: Patch immediately. Since it is unauthenticated and allows RCE, it is a prime target for automated bots. β³ **Time**: Do not delay remediation.
