Compliance Impact

The vulnerability allows the account validation endpoint to return comprehensive user profile data sheets that can be accessed by iterating predictable identification strings. This exposure of detailed user data without proper access controls can lead to unauthorized data disclosure.

Such unauthorized disclosure of personal data can negatively impact compliance with data protection regulations like GDPR and HIPAA, which require strict controls on personal data access and processing to protect user privacy and ensure data security.

Detection Guidance

This vulnerability involves the account validation endpoint /v1/User/validate returning comprehensive user profile data sheets that can be crawled by iterating predictable identification strings.

To detect this vulnerability on your network or system, you can attempt to access the /v1/User/validate endpoint with sequential or predictable user IDs to see if user profile data is returned without proper authorization.

A simple command using curl to test this could be:

• curl -X GET http://[target-ip]/v1/User/validate?id=1
• curl -X GET http://[target-ip]/v1/User/validate?id=2

By iterating over the id parameter, you can check if the endpoint returns user profile data without authentication, indicating the presence of the vulnerability.
