CVE の説明
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.CVE の解決策
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:
