Grandstream GWN7000 firmware version 1.0.9.4 and below allows authenticated remote users to modify the systems crontab via undocumented API. An attacker can use this functionality to execute arbitrary OS commands on the router.
The product is deployed to unauthorized actors with debugging code still enabled or active, which can create unintended entry points or expose sensitive information.
