How the Exploit Works
The exploit takes advantage of a local control script known as transmit_file. This script is vulnerable to command injection, which allows a potential attacker to inject malicious commands that can be executed by the system. This is due to improper neutralization of argument delimiters in a command, also known as ‘Argument Injection’ (CWE-88).
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited using a shell command:
$ ./transmit_file --host=127.0.0.1 --port=80 --payload='; rm -rf /'In this conceptual example, the injected command (`; rm -rf /`) would delete all files in the system if executed. Please note that this is a conceptual example and the actual exploitation might be different based on the system configuration and the attacker’s intent.
Mitigation Guidance
As of the time of this report, the vendor has not released a patch for this vulnerability. Until one is available, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as temporary mitigation. Additionally, the vendor has released a best practices guide that should be followed to minimize the risk of this vulnerability.
