Executive Summary

This vulnerability exists in migration-planner where an authenticated user can send a DELETE request to the /api/v1/sources route.

The route lacks proper authorization and filtering, which means the user can delete all customer data including sources, agents, and assessments.

This leads to a critical loss of availability and integrity across the entire SaaS platform.

Detection Guidance

This vulnerability can be detected by monitoring for DELETE requests sent to the /api/v1/sources endpoint from authenticated users. Since the endpoint allows unfiltered deletion of all tenant data, any such DELETE request is suspicious and indicative of exploitation attempts.

You can use network monitoring or web server logs to identify DELETE requests to /api/v1/sources. For example, using command-line tools like curl or HTTP client tools to test if the endpoint responds without proper authorization can help detect the vulnerability.

• Use curl to test the endpoint (replace <host> and provide authentication token if needed):
• curl -X DELETE https://<host>/api/v1/sources -H "Authorization: Bearer <token>" -v
• Check web server or application logs for DELETE requests to /api/v1/sources.
• Use network monitoring tools (e.g., tcpdump, Wireshark) to filter HTTP DELETE requests targeting /api/v1/sources.

Impact Analysis

Exploiting this vulnerability allows an authenticated user to destroy all customer data such as sources, agents, and assessments.

This results in a critical loss of availability and integrity of the SaaS platform, potentially causing significant disruption to services and data loss.

Compliance Impact

The vulnerability allows an authenticated user to delete all customer data, including sources, agents, and assessments, leading to a critical loss of data availability and integrity across the entire SaaS platform.

Such a loss of data integrity and availability can negatively impact compliance with common standards and regulations like GDPR and HIPAA, which require protection of personal and sensitive data, ensuring its confidentiality, integrity, and availability.

Specifically, the ability to destroy all tenant data without proper authorization could result in violations of data protection requirements, potentially leading to regulatory penalties and loss of trust.

Mitigation Strategies

Immediate mitigation involves disabling the vulnerable DELETE /api/v1/sources handler so that it returns a 401 Unauthorized error, preventing any authenticated user from exploiting the endpoint.

Longer-term fixes include removing the DELETE /api/v1/sources route entirely from the API specification and codebase or implementing organization-scoped bulk delete functionality with explicit edit permissions.

Additionally, the vulnerability has been addressed by removing the insecure bulk delete endpoint and replacing it with an endpoint that requires specifying individual source IDs for deletion, enforcing stricter access control.
