Detailsinfo

A vulnerability, which was classified as problematic, has been found in WSO2 API Manager, Carbon Identity Application, Carbon Identity Core, Carbon Identity Oauth, Identity Server, Identity Server as Key Manager, Open Banking AM and Open Banking IAM. Affected by this issue is an unknown code. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality. CVE summarizes:

The product failed to enforce validation constraints on user-supplied input in URL parameters, allowing sensitive data to be passed to flows where it was not intended to be processed. Although the product did not utilize this data, its acceptance could lead to logging. If a user mistakenly sends sensitive data via URL parameters to any flow, this data could be inadvertently logged in access logs. This has the potential to expose confidential information, compromising the security and privacy of affected systems if the product is used incorrectly.
