Detailsinfo

A vulnerability classified as critical has been found in Eclipse Kura up to 5.6.2. This affects some unknown functionality of the component Beacon Scanner. The manipulation with an unknown input leads to a infinite loop vulnerability. CWE is classifying the issue as CWE-835.

In Eclipse Kura versions 3.1.0 to 5.6.2, the iBeacon and Eddystone advertisement decoders wrongly parse the AD-structure length field of an over-the-air BLE advertising payload. Any unauthenticated attacker within BLE radio range can broadcast a two-byte advertising payload that drives the Kura beacon-scanner thread into a tight infinite loop, pinning a CPU core and permanently halting beacon ingestion until the gateway is restarted. To trigger the attack, the iBeacon/Eddystone scanner component should be installed and active. By default the components are not installed or enabled.
