Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: OS Command Injection in WAVLINK routers. π **Consequences**: Attackers can execute arbitrary commands, steal data, modify system files, or take full control of the device. Itβs a critical security breach.
π¦ **Affected**: WAVLINK WN535K2 and WN535K3 wireless routers. π **Vendor**: WAVLINK (China). β οΈ **Component**: The mesh.cgi CGI script is the vulnerable entry point.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Full system control (Root/Admin level). π **Data**: Sensitive information theft, malware installation, and data modification.β¦
π **Auth Required**: Yes, Local Privileges (PR:L). π **Access**: Attacker must have Local Network Access (AV:A). πΆ **Complexity**: Low (AC:L). Itβs not remote unauthenticated, but local network access is easy to obtain.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp**: Yes. π **PoC**: Available via Nuclei templates (ProjectDiscovery). π **Status**: Known vulnerability with documented exploitation methods. Wild exploitation is possible for those with local access.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for `/cgi-bin/mesh.cgi?page=upgrade`. π§ͺ **Test**: Manipulate the `key` parameter with command injection payloads. π οΈ **Tool**: Use Nuclei or custom scripts to detect the specific CVE signature.
π§ **Workaround**: Restrict network access to the routerβs management interface. π« **Block**: Prevent local network users from accessing `/cgi-bin/mesh.cgi`.β¦
π₯ **Priority**: HIGH. π **CVSS**: 9.8 (Critical). π¨ **Urgency**: Immediate attention required. Even with local auth, the impact is total system compromise. Don't ignore this!
