How the Exploit Works
The exploit targets a local control script, router_command.sh, in the ‘put_file_to_qtn’ argument. Due to improper neutralization of argument delimiters in a command (CWE-88), an attacker can inject commands that the system processes. This command injection vulnerability allows an attacker to execute arbitrary commands on the target system, potentially compromising the system or leaking data.
Conceptual Example Code
The following conceptual example demonstrates how the vulnerability might be exploited. The attacker injects a malicious command into the ‘put_file_to_qtn’ argument of the ‘router_command.sh’ script.
./router_command.sh put_file_to_qtn "/tmp; cat /etc/passwd > /tmp/passwd_copy"In this example, the attacker tricks the system into executing a command that copies the contents of the ‘/etc/passwd’ file to a ‘/tmp/passwd_copy’, potentially leaking sensitive data.
Mitigation Measures
To mitigate this vulnerability, users should apply the vendor’s patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can help protect against potential exploits. Implementors of this chipset are also advised to follow the best practices guide released by the vendor.
