Description

A vulnerability in SenseLive X3050's web management interface allows critical system and network configuration parameters to be modified without sufficient validation and safety controls. Due to inadequate enforcement of constraints on sensitive functions, parameters such as IP addressing, watchdog timers, reconnect intervals, and service ports can be set to unsupported or unsafe values. These configuration changes directly affect core device behaviour and recovery mechanisms. The lack of proper validation and safeguards allows critical system functions to be altered in a manner that can destabilize device operation or render the device persistently unavailable.
