CVE 描述
GE Hydran M2 Predictable Value Range from Previous Values
The 17046 Ethernet card before 94450214LFMT100SEM-L.R3-CL for the GE Digital Energy Hydran M2 does not properly generate random values for TCP Initial Sequence Numbers (ISNs), which makes it easier for remote attackers to spoof packets by predicting these values.CVE 解決方案
GE Digital Energy has released a new version of the Ethernet option,
which resolves the identified vulnerability in newly released Hydran M2
devices. The update changes the sequence algorithm, which makes it
improbable that a TCP sequence attack could succeed. The version of
Ethernet card that implements this improvement is
94450214LFMT100SEM-L.R3-CL.

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。
