## Technical details

A command injection vulnerability exists in the 'system.setclock' interface of Cudy TR1200 (v2.4.15) and TR3000 (v2.4.21) routers. The flaw stems from insufficient sanitization of user-supplied input passed to system-level commands responsible for setting the device clock. An unauthenticated remote attacker can exploit this by sending a specially crafted request to the affected interface, leading to arbitrary command execution with root privileges. This allows for full system compromise, including persistent access and lateral movement within the local network.

## Affected products
