AV:N/AC:L/Au:N/C:N/I:P/A:N

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.

Remedy

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

XSS
AV:N/AC:M/Au:S/C:N/I:P/A:N

Multiple cross-site scripting (XSS) vulnerabilities in Schneider Electric StruxureWare SCADA Expert ClearSCADA 2010 R3 through 2014 R1 allow remote authenticated users to inject arbitrary web script or HTML via unspecified vectors.

Remedy

Schneider Electric advises all ClearSCADA users to take steps to secure the interfaces to the ClearSCADA system. The ClearSCADA database security configuration should be reviewed and updated to limit all system access to authorized users only. The access permissions of existing users should be reduced to only those required by their role (e.g., removing any higher level System Administration privileges from Operations or Engineering users), and specific accounts should be created with appropriate permissions for performing System Administration tasks. Existing ClearSCADA customers using WebX can protect their system from cross-site scripting attacks by disabling the “Allow database shutdown via WebX” option within the ClearSCADA Server Configuration utility. Existing ClearSCADA customers should take measures to ensure their system does not grant any system access until users have supplied a valid username and password. Schneider Electric has corrected the default user security permissions; however, upgrading an existing vulnerable installation to a new version will not affect existing configured database security permissions. Therefore, the measures suggested here are strongly recommended for all users. Schneider Electric has corrected these vulnerabilities in the following service packs: * ClearSCADA 2010 R3.2, Released October 2014, and * SCADA Expert ClearSCADA 2014 R1.1, Released October 2014. If asset owners wish to upgrade to a new ClearSCADA Service Pack, please contact the local Schneider Electric office for the latest software version for ClearSCADA; alternatively, these new versions are available for direct download from the Schneider Electric web site. To update their license (not required when upgrading to a service pack of the same version), asset owners are required to complete and submit an online form, which is available here: http://resourcecenter.controlmicrosystems.com/display/CS/StruxureWare+SCADA+Expert+ClearSCADA+Update... http://resourcecenter.controlmicrosystems.com/display/CS/StruxureWare+SCADA+Expert+ClearSCADA+Update+Request+Form New Service packs for ClearSCADA are available for download here: http://resourcecenter.controlmicrosystems.com/display/CS/SCADA+Expert+ClearSCADA+Support General instructions on how to upgrade the ClearSCADA license (if required) are available here: http://resourcecenter.controlmicrosystems.com/display/CS/Updating+Your+ClearSCADA+License
