Vulnerability Description:

The ping and traceroute functions of the NETIS SYSTEMS Router WF2409E (version V3.6.42541) are susceptible to command injection attacks. Malicious input can be crafted in the parameters of these functions through the Web admin management interface, allowing arbitrary commands to be executed with the privileges of the affected process.

3. Craft Malicious Input:

   • In the "Ping" function input field, inject a command. For example:

;ls /* -al|ps

4. Execute the Command:

   • Observe the output. If the directory listing of the router's filesystem is displayed, the command injection is successful.

5. Open the Traceroute Function:

   • Navigate back to the "Diagnostic Tools" section.
   • Select the "Traceroute" function.

6. Craft Malicious Input:

   • In the "Traceroute" function input field, inject a command. For example:

     | ls
     

7. Execute the Command:

   • Submit the crafted input.
   • Check if the output includes the result of the ls command. If so, the command injection is demonstrated.
