A vulnerability has been identified in Mendix Runtime V7 (All versions < V7.23.29), Mendix Runtime V8 (All versions < V8.18.16), Mendix Runtime V9 (All versions < V9.13 only with Runtime Custom Setting DataStorage.UseNewQueryHandler set to False). If an entity has an association readable by the user, then in some cases, Mendix Runtime may not apply checks for XPath constraints that parse said associations, within apps running on affected versions. A malicious user could use this to dump and manipulate sensitive data.

Weakness

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Affected Software

Name Vendor Start Version End Version
Mendix Mendix * 7.23.29 (excluding)
Mendix Mendix 8.0.0 (including) 8.18.16 (excluding)
Mendix Mendix 9.0.0 (including) *

Extended Description

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
