The impact of this vulnerability is that an unauthenticated user can craft a malicious XML data file that allows them to access sensitive information or configuration files, potentially impacting the availability of the affected application.

This vulnerability is classified as high risk and has therefore been given a CVSS (Common Vulnerability Scoring System) of 8.6.

What can you do?

Applied Risk has worked alongside Sauter in the responsible disclosure process, with the vendor releasing a patch. It is recommended to organisations utilising the SAUTER CASE Suite building automation software to update to the latest version.
