How the Exploit Works

The flaw lies in the local control script, router_command.sh, specifically in the get_file_from_qtn argument. This vulnerability can be exploited by injecting malicious commands into the argument, causing the system to execute these unwanted commands. This could potentially compromise the system or lead to data leakage.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited via command injection:

./router_command.sh get_file_from_qtn 'addr; rm -rf /' # This command will remove all the files in the root directory.

In this example, the argument following the semi-colon is interpreted as a separate command, which could lead to a potential system compromise.

Recommendation

We strongly recommend applying the vendor patch as soon as it becomes available. Until then, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure. Implementors are also encouraged to follow the best practices guide released by the vendor.
