Description

dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, a Standard user can enumerate other users' names and email addresses through `/users/search`, even though direct access to those user profiles is denied. This leaks internal staff addresses, full names, and existence of guest and external test accounts.

Executive Summary

This vulnerability in dataCycle-CORE allows a standard user to enumerate other users' names and email addresses through the /users/search endpoint. Even when direct access to user profiles is restricted, this flaw exposes internal staff contact details, full names, and the existence of guest or external test accounts.

Detection Guidance

To detect this vulnerability, check if your dataCycle-CORE version is 25.07.3 or earlier. Use the endpoint /users/search with a standard user account to see if it returns other users' names and email addresses. If it does, the system is vulnerable.

Impact Analysis

The vulnerability can lead to privacy breaches by exposing sensitive user information such as email addresses and full names. It may also reveal the presence of guest or external accounts, potentially aiding social engineering attacks or unauthorized reconnaissance of an organization's internal structure.

Compliance Impact

This vulnerability could violate data protection regulations like GDPR and HIPAA by exposing personally identifiable information (PII) without consent. GDPR requires protecting personal data, and HIPAA mandates safeguarding protected health information, making this a compliance risk.

Mitigation Strategies

Immediately upgrade dataCycle-CORE to version 26.06.08 or later to patch the vulnerability. If upgrading is not possible, restrict access to the /users/search endpoint or implement additional access controls to prevent unauthorized enumeration.
