Detailsinfo

A vulnerability classified as problematic has been found in WSO2 Identity Server, Identity Server as Key Manager, Identity Server Keystore Rest API Commons, Identity Server Keystore Rest API V1 and Open Banking IAM. Affected is an unknown function of the component Content-Type Validation. The manipulation of the argument content-type with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

The affected component fails to enforce expected validation constraints on the `content-type` header when processing certain requests. This allows an attacker to submit a crafted request with a manipulated `content-type` header. Successful exploitation can lead to the unintended exposure of the file paths for certificate files. This information disclosure could potentially be leveraged in subsequent attacks or compromise the confidentiality of the system.
