07 Remediation

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.
