CVE 描述
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 解決方案
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.

EPSS
EPSS 是一種預測漏洞被利用可能性的評分模型。
EPSS 評分
EPSS 模型產生介於 0 到 1（0% 到 100%）之間的概率分數。分數越高，漏洞被利用的概率越大。
EPSS 百分位數
百分位數用於根據 EPSS 分數對 CVE 進行排名。例如，EPSS 評分在第 95 百分位的 CVE 比 95% 的其他 CVE 更有可能被利用。因此，百分位數用於比較某 CVE 的 EPSS 分數與其他 CVE 的相對位置。
