Technical details
An out-of-bounds (OOB) write vulnerability exists in Silicon Labs EmberZNet v9.0.2 and earlier within the handling of Intruder Alarm System (IAS) Zone enrollment messages. The root cause is a failure to properly validate malformed enrollment messages, which triggers an OOB write to the state-table. While the size and location of the write are limited, it is sufficient to terminate the process (Denial of Service). Exploitation requires the attacker to be using a device that has already successfully joined the Zigbee network (PR:L) and targets devices supporting the IAS Zone cluster. Silicon Labs has addressed this in newer releases of the Simplicity SDK / EmberZNet.
