Description

A vulnerability has been identified in Mendix Encryption (All versions >= V10.0.0 < V10.0.2). Affected versions of the module define a specific hard-coded default value for the EncryptionKey constant, which is used in projects where no individual EncryptionKey was specified. This could allow to an attacker to decrypt any encrypted project data, as the default encryption key can be considered compromised.

Affected products

Siemens Mendix Encryption: from V10.0.0 before V10.0.2 — fixed in V10.0.2

How to fix

Upgrade to a fixed version: Siemens Mendix Encryption V10.0.2. Check the vendor advisory for mitigations.
