Affected Software

Weaknesses

• CWE-79: CWE-79 Cross-site Scripting

Workarounds

SUBNET Solutions recommends users to follow the following workarounds:

• Users should verify that SVG files do not contain HTML elements or scripts and validate that JPG and PNG files are not SVG files.
• Users should verify network security rules to ensure that outbound connections to the internet are not possible.
• If the above cannot be performed or notifications are not required, disable email notifications for reports from PowerSYSTEM Center.
• Monitor user activity and ensure application control rules only allow preauthorized executables to run.
• Deny users to run other executables on client access servers (PowerSYSTEM Center front end access point).
