CVE 描述
GE Multilink Use of Hard-coded Cryptographic Key
GE Multilink ML800, ML1200, ML1600, and ML2400 switches with firmware 4.2.1 and earlier and Multilink ML810, ML3000, and ML3100 switches with firmware 5.2.0 and earlier use the same RSA private key across different customers' installations, which makes it easier for remote attackers to obtain the cleartext content of network traffic by reading this key from a firmware image and then sniffing the network.CVE 解決方案
GE recommends users update switch firmware to the
latest published version to resolve these vulnerabilities. The new
firmware will enable new keys to be calculated and exchanged, resolve
the slow data transfer and potential denial of service, and prevent the identified
cross-site scripting vulnerabilities. The latest firmware is Version
5.3.2 for the ML800, ML1200, ML1600 and ML2400 and Version 5.3.2-3K for
the ML810, ML3000, and ML3100. This firmware is available through the
“Resources/Software” link in the product web sites at
http://www.gedigitalenergy.com . This firmware is also available through
the EnerVista Launchpad device management tool.
GE recommends updating the switch over a serial connection to prevent an attacker from capturing the new key.
Please refer to the GE advisory for specific information on how to
install the firmware and change RSA key. The GE advisory is available

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。
