Detailsinfo

A vulnerability classified as problematic has been found in Siemens Mendix Runtime (unknown version). This affects an unknown code block of the component Basic Authentication Handler. The manipulation with an unknown input leads to a response discrepancy vulnerability. CWE is classifying the issue as CWE-204. The product provides different responses to incoming requests in a way that reveals internal state information to an unauthorized actor outside of the intended control sphere. This is going to have an impact on confidentiality. The summary by CVE is:

A vulnerability has been identified in Mendix Runtime V10 (All versions < V10.14.0 only if the basic authentication mechanism is used by the application), Mendix Runtime V10.12 (All versions < V10.12.2 only if the basic authentication mechanism is used by the application), Mendix Runtime V10.6 (All versions < V10.6.12 only if the basic authentication mechanism is used by the application), Mendix Runtime V8 (All versions only if the basic authentication mechanism is used by the application), Mendix Runtime V9 (All versions < V9.24.26 only if the basic authentication mechanism is used by the application). The authentication mechanism of affected applications contains an observable response discrepancy vulnerability when validating usernames. This could allow unauthenticated remote attackers to distinguish between valid and invalid usernames.
