Details

Cudy LT300 3.0 running firmware prior to version 2.5.12 contains an OS command injection vulnerability that allows authenticated attackers to execute arbitrary commands by injecting shell metacharacters into the cbid.system.ntp.current POST parameter in the system time configuration interface. Attackers can submit malicious payloads through the NTP settings endpoint to achieve remote code execution on the underlying system.
