CWE-547

Use of Hard-coded, Security-relevant Constants

The product uses hard-coded constants instead of symbolic names for security-critical values, which increases the likelihood of mistakes during code maintenance or security policy change.

CWE
  • CWE-547 - Use of Hard-coded, Security-relevant Constants
Summary
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.
