Wso2 Carbon Api Management Implementation

The XML and schema validation functionalities within the SchemaValidator Mediator process XML input as part of validation flows. Under certain conditions, the XML parser allows the resolution of external entities when handling user-supplied XML content during validation operations. This behavior can occur when an attacker supplies crafted XML payloads to the relevant mediator flows with sufficient privileges. Successful exploitation may allow a highly privileged actor to read files accessible within the server hosting the affected product. Additionally, it may be possible to trigger outbound requests to unintended internal or external locations, depending on the server environment and network configuration. Specially crafted XML payloads can also lead to excessive resource consumption during parsing, impacting the availability of the product.

The System REST API accepts user-supplied file uploads without enforcing sufficient validation on the file type or destination, allowing files to be written to arbitrary server-accessible locations. Exploitation requires authenticated administrative access with publisher privileges. Successful exploitation permits an authenticated publisher to upload files to server-accessible locations. Depending on the deployment environment and how uploaded files are handled, this could lead to the execution of uploaded content, potentially resulting in remote code execution.

In multi-tenant deployments, the Publisher REST APIs fail to enforce tenant isolation correctly. This allows a user in one tenant, possessing sufficient privileges to invoke these APIs, to perform operations that impact other tenants. The vulnerability allows a privileged user to perform publisher operations such as exposing or modifying API Metadata in another tenant environment. This impact is only realized in multi-tenant deployments.
