CVE-2015-5498 in Shipwire API Module
Summary
by MITRE
The Shipwire API module 7.x-1.x before 7.x-1.03 for Drupal does not check the view permission for the shipments overview (admin/shipwire/shipments), which allows remote attackers to obtain sensitive information via a request to the page.

The vulnerability identified as CVE-2015-5498 affects the Shipwire API module version 7.x-1.x before 7.x-1.03 in the Drupal content management system. This security flaw represents a critical access control bypass that undermines the fundamental security model of the platform. The Shipwire module integrates with the Drupal administration interface to provide shipment tracking and management capabilities, but the vulnerability specifically targets the shipments overview page located at admin/shipwire/shipments. This page contains sensitive operational data including shipment details, tracking numbers, and customer information that should only be accessible to authorized administrators.
The technical implementation flaw stems from the absence of proper permission validation within the module's access control mechanisms. When a remote attacker makes a request to the shipments overview page, the module fails to verify whether the requesting user possesses the necessary view permissions. This omission creates an unauthorized information disclosure vulnerability that directly violates the principle of least privilege and proper access control enforcement. The vulnerability exists at the application logic level where authentication and authorization checks are insufficiently implemented, allowing any authenticated user to access restricted administrative functionality without proper authorization.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with access to potentially sensitive shipment data that may include customer personal information, shipping addresses, and commercial logistics details. This exposure creates risks for organizations using the module, particularly those in e-commerce or logistics sectors where shipment data represents valuable business intelligence and customer privacy concerns. Attackers could leverage this vulnerability to gain insights into supply chain operations, customer shipping patterns, and potentially identify high-value targets for further attacks. The remote nature of the exploit means that attackers do not require physical access or local network presence to exploit this vulnerability, making it particularly dangerous for web-facing applications.
The vulnerability aligns with CWE-285, which addresses improper authorization issues in software systems, and demonstrates how insufficient access control checks can lead to unauthorized data access. From an attack framework perspective, this vulnerability maps to the privilege escalation and information gathering phases of the MITRE ATT&CK framework, specifically targeting the credential access and discovery categories. Organizations should implement immediate mitigations including updating to the patched version 7.x-1.03 of the Shipwire module, reviewing existing access controls for administrative pages, and implementing additional monitoring for unauthorized access attempts to sensitive administrative interfaces. The incident underscores the critical importance of proper access control implementation in web applications and the necessity of thorough security testing of third-party modules before deployment in production environments.
