Deskripsi CVE
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.Solusi CVE
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 adalah model penilaian yang memprediksi kemungkinan suatu kerentanan dieksploitasi.
Skor EPSS
Model EPSS menghasilkan skor probabilitas antara 0 dan 1 (0 hingga 100%). Semakin tinggi skor, semakin besar probabilitas bahwa suatu kerentanan akan dieksploitasi.
Persentil EPSS
Persentil digunakan untuk meranking CVE berdasarkan skor EPSS mereka. Misalnya, CVE di persentil ke-95 berdasarkan skor EPSS-nya lebih mungkin dieksploitasi daripada 95% CVE lainnya. Dengan demikian, persentil digunakan untuk membandingkan skor EPSS suatu CVE dengan CVE lainnya.
