How the Exploit Works

The vulnerability exists in the router_command.sh script, specifically in the get_syslog_from_qtn argument. This script does not properly neutralize argument delimiters, allowing for argument injection. This scenario is classified as CWE-88. An attacker can exploit this vulnerability to inject commands directly into the system, potentially leading to unauthorized access, data leaks, or even a complete system takeover.

Conceptual Example Code

An attacker might exploit this vulnerability by sending a specially crafted command, as shown in the conceptual example below:

./router_command.sh get_syslog_from_qtn '; malicious_command'

In this example, the semicolon allows the attacker to execute “malicious_command” after the legitimate command “get_syslog_from_qtn”. This command could be designed to compromise the system or exfiltrate sensitive data.

Mitigation Guidance

While the vendor has yet to release a patch for this vulnerability, they have published a best practices guide for implementors of this chipset. In the interim, it may also be advisable to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure, ensuring they are configured to detect and block malicious command injection attempts.
