Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Stack Buffer Overflow in Tenda WH450. π₯ **Consequences**: Full system compromise. Remote Code Execution (RCE) is possible via the `/goform/CheckTools` endpoint.β¦
π‘οΈ **Root Cause**: CWE-121 (Stack-based Buffer Overflow). π **Flaw**: Improper handling of the `ipaddress` parameter in the `CheckTools` script. Input exceeds buffer limits, corrupting stack memory.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: Tenda WH450 Wireless Access Point. π **Version**: Specifically **v1.0.0.18**. β οΈ Check your firmware version immediately if you own this device.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Likely Root/System level. π **Data**: Full access to device data. π **Action**: Hackers can execute arbitrary commands, install backdoors, or pivot to your internal network.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: LOW. π« **Auth**: No authentication required (PR:N). π **Access**: Network accessible (AV:N). π±οΈ **UI**: No user interaction needed (UI:N). Easy remote exploitation.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π» **Exploit**: YES. π **Source**: Public PoC available on GitHub (`z472421519/BinaryAudit`). π **Status**: Active exploitation indicators exist. Do not wait for a patch.
π§ **Workaround**: Block external access to port 80/443. π **Filter**: Use WAF to block requests containing `CheckTools` or suspicious `ipaddress` payloads. π **Isolate**: Segment the device on a guest network.
