CVE 설명
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 해결 방법
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
EPSS는 취약점이 악용될 가능성을 예측하는 점수 모델입니다.
EPSS 점수
EPSS 모델은 0과 1(0~100%) 사이의 확률 점수를 생성합니다. 점수가 높을수록 취약점이 악용될 가능성이 높습니다.
EPSS 백분위수
백분위수는 EPSS 점수에 따라 CVE의 순위를 매기는 데 사용됩니다. 예를 들어 EPSS 점수 기준 95번째 백분위수의 CVE는 다른 CVE의 95%보다 악용될 가능성이 높습니다.
