Summary
SSA-097435: Usernames Disclosure Vulnerability in Mendix Runtime
Notes
Summary
Mendix Runtime contains an observable response discrepancy vulnerability when validating usernames during authentication. This could allow unauthenticated remote attackers to distinguish between valid and invalid usernames.
Siemens has released new versions for the affected products and recommends to update to the latest versions.
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.
