Mô tả CVE

Schneider Electric SCADA Expert ClearSCADA Cryptographic Issues

Schneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R3 through 2014 R1 uses the MD5 algorithm for an X.509 certificate, which makes it easier for remote attackers to spoof servers via a cryptographic attack against this algorithm.

Giải pháp CVE

Asset owners should always obtain a signed web certificate from a certified authority before deploying ClearSCADA Web Server in a production environment. To assist asset owners who are currently using self-signed certificates, a standalone utility will be made available that can be used to generate and deploy a new self-signed certificate (signed using an SHA signing algorithm). This utility is recommended for existing ClearSCADA systems subject to this vulnerability, removing the need to upgrade the ClearSCADA software and perform a manual generation of a new certificate. This utility will be made available within the Software Downloads section of the following ClearSCADA Resource Center page: http://resourcecenter.controlmicrosystems.com/display/CS/SCADA+Expert+ClearSCADA+Support

EPSS

EPSS là mô hình tính điểm dự đoán khả năng một lỗ hổng bị khai thác.

Điểm EPSS

Mô hình EPSS tạo ra điểm xác suất từ 0 đến 1 (0 đến 100%). Điểm càng cao, xác suất một lỗ hổng bị khai thác càng lớn.

Phân vị EPSS

Phân vị được dùng để xếp hạng CVE theo điểm EPSS. Ví dụ, một CVE ở phân vị thứ 95 theo điểm EPSS có nhiều khả năng bị khai thác hơn 95% CVE khác. Do đó, phân vị được dùng để so sánh điểm EPSS của một CVE với các CVE khác.
