Technical details
A CWE-78 OS command injection vulnerability exists in the asp_setPing endpoint of Edimax BR-6214K firmware 1.40. The pingstr parameter submitted to /goform/asp_setPing is passed directly into a system() call without proper sanitization or escaping of shell metacharacters. The attack requires valid web-management (admin) credentials and network access to the router's management interface. An authenticated attacker can inject shell commands (e.g., ;id;#) that are executed with the privileges of the Boa web server, which runs as root. The vulnerability has been publicly disclosed with proof-of-concept code available, and the vendor has not responded to early disclosure requests.
