CVE-2024-43188

IBM Business Automation Workflow

22.0.2, 23.0.1, 23.0.2, and 24.0.0

could allow a privileged user to perform unauthorized activities due to improper client side validation.

Weakness

The product is composed of a server that relies on the client to implement a mechanism that is intended to protect the server.

Affected Software

Potential Mitigations

• For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
• Even though client-side checks provide minimal benefits with respect to server-side security, they are still useful. First, they can support intrusion detection. If the server receives input that should have been rejected by the client, then it may be an indication of an attack. Second, client-side error-checking can provide helpful feedback to the user about the expectations for valid input. Third, there may be a reduction in server-side processing time for accidental input errors, although this is typically a small savings.
