CVE 설명
Post Oak Bluetooth Traffic Systems Insufficient Entropy
Post Oak AWAM Bluetooth Reader Traffic System does not use a sufficient source of entropy for private keys, which makes it easier for man-in-the-middle attackers to spoof a device by predicting a key value.CVE 해결 방법
Post Oak has developed a patch for the AWAM Bluetooth Reader Traffic
System that mitigates the vulnerability. The patch allows the Bluetooth
reader to ensure sufficient entropy exists before generating host and
authentication keys. The patch will be installed on all new devices when
initially configured. Existing equipment will be patched by remote
access and upgraded to the latest firmware. System owners are encouraged
to contact Post Oak Traffic Systems,
support@postoaktraffic.com, (281) 381-2887. with questions patching their systems.
