Attack-Flow Graph

Executive Summary

This vulnerability affects the U.S. Government Accountability Office (GAO) Electronic Protest Docketing System (EPDS) and the Civilian Board of Contract Appeals (CBCA) Electronic Docketing System (EDS). It occurs because the 'update-profile/' API endpoint exposes sensitive account information. A remote attacker who is not authenticated can send a request with any arbitrary 'user_id' parameter and receive a JSON response containing account-specific details, including the associated email address.

Impact Analysis

The vulnerability allows an unauthenticated remote attacker to access sensitive account information such as email addresses by exploiting the 'update-profile/' API endpoint. This exposure can lead to privacy breaches, targeted phishing attacks, or further exploitation by attackers using the obtained account details.

Compliance Impact

The vulnerability exposes sensitive account information, including email addresses, through an unauthenticated API endpoint. This exposure of personal data could potentially impact compliance with data protection regulations such as GDPR and HIPAA, which require safeguarding personal and sensitive information from unauthorized access.

However, specific details on how this vulnerability affects compliance with these standards or any mitigation measures are not provided in the available information.
