Summary
SSA-779699: Two Incorrect Authorization Vulnerabilities in Mendix

Notes

Summary
Applications built with affected versions of Mendix Studio Pro do not properly control read or write access for certain client actions. This could allow authenticated attackers to manipulate the content of System.FileDocument objects or to retrieve the changedDate attribute of arbitrary objects. Mendix has released updates for the affected product lines, recommends to update to the latest versions and to redeploy the applications.
General Recommendations
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
