After receiving a
malformed 802.15.4 MAC Data Request
the Zigbee Coordinator sends a ‘network leave’ request to Zigbee router resulting in the Zigbee Router getting stuck in a non-rejoinable state. If a suitable parent is not available, the end devices will be unable to rejoin. A manual recommissioning is required to recover the Zigbee Router.
Weakness
The product does not properly handle when the expected number of values for parameters, fields, or arguments is not provided in input, or if those values are undefined.
