Deloitte AI Assist for Customer Configuration Modification

Mitigation Strategies

The vulnerability was mitigated by restricting network access and enforcing authentication for the previously exposed public-facing API endpoints.

Therefore, immediate steps should include ensuring that network access to these API endpoints is restricted and that authentication is enforced to prevent unauthenticated POST requests.

Useful 0 Not Useful 0

Executive Summary

This vulnerability involves Deloitte AI Assist for Customer accepting unauthenticated POST requests through its public-facing API endpoints. This allowed a remote attacker to make limited additions to the system's configuration without needing to authenticate.

However, these additions were not actually used by the system, reducing the potential impact. The issue was addressed on 2026-03-25 by restricting network access and enforcing authentication on the previously exposed endpoints.

Detection Guidance

The vulnerability involves unauthenticated POST requests accepted through public-facing API endpoints of Deloitte AI Assist for Customer. Detection can focus on monitoring network traffic for such POST requests to these endpoints without authentication.

You can use network monitoring tools like curl or wget to test if the API endpoints accept unauthenticated POST requests. For example, sending a POST request to the suspected API endpoint and checking the response status can help identify if the vulnerability exists.

• curl -X POST https://<target-domain>/api/endpoint -d '{"test":"data"}' -v
• tcpdump or Wireshark to capture and analyze HTTP POST requests to the API endpoints.

Since the vulnerability was mitigated by restricting network access and enforcing authentication as of 2026-03-25, testing for unauthenticated access after this date can confirm if the fix is applied.
