Executive Summary

This is a Server-Side Request Forgery (SSRF) and information disclosure vulnerability in Airbyte's SharePoint Connector. It exists in the _get_shared_drive_object method due to improper validation of a URI before accessing resources. Attackers with authentication can exploit this to make arbitrary server-side requests and disclose information in the context of the service account.

Detection Guidance

Detecting this vulnerability requires monitoring for unusual server-side requests initiated by authenticated users. Check logs for requests to internal or external URIs that are not expected. Look for anomalies in network traffic patterns from the Airbyte service account. Review access logs for unauthorized access to sensitive resources.

Impact Analysis

An attacker could leverage this to access internal resources, exfiltrate sensitive data, or perform unauthorized actions on behalf of the service account. The impact includes potential data breaches, unauthorized system access, and compromise of confidential information.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR, HIPAA, and other regulations due to unauthorized data access or disclosure. It may result in legal penalties, loss of trust, and failure to meet data protection requirements.

Mitigation Strategies

Immediately restrict network access to the Airbyte service to trusted sources only. Disable or limit the functionality of the _get_shared_drive_object method if possible. Ensure the service account used by Airbyte has minimal privileges. Monitor for any suspicious activity and apply patches or updates as soon as they become available.
