CVE-2012-2702 in Ubercart Product Keys
Summary
by MITRE
The Ubercart Product Keys module 6.x-1.x before 6.x-1.1 for Drupal does not properly check access for product keys, which allows remote attackers to read all unassigned product keys via certain conditions related to the uid.

The vulnerability identified as CVE-2012-2702 affects the Ubercart Product Keys module version 6.x-1.x before 6.x-1.1 in the Drupal content management system. This security flaw represents a critical access control weakness that undermines the integrity of product key management within e-commerce platforms built on Drupal. The module specifically handles digital product licensing and key distribution, making it a prime target for attackers seeking unauthorized access to commercial software licenses.
The technical flaw stems from insufficient access control validation within the module's code implementation. When processing requests for product keys, the system fails to properly verify user permissions based on the uid parameter, which identifies the user account associated with a particular key. This improper access check creates a path where authenticated users can manipulate request parameters to access product keys that should remain restricted to specific users or administrators. The vulnerability operates at the application logic level, where the module's authorization mechanisms are bypassed through parameter manipulation.
The operational impact of this vulnerability extends beyond simple information disclosure, as it enables attackers to potentially compromise software licensing systems and intellectual property. Remote attackers can exploit this weakness to enumerate and access all unassigned product keys, which may contain valuable licensing information, activation codes, or other sensitive data required for software distribution. This exposure could lead to unauthorized software distribution, revenue loss for software vendors, and potential legal implications regarding software piracy and licensing compliance.
Security researchers categorize this vulnerability under CWE-284, which describes improper access control conditions where a system fails to properly enforce access restrictions. The attack vector aligns with ATT&CK technique T1078.004, which involves valid accounts with limited privileges being used to gain access to additional resources. Organizations running vulnerable Drupal installations with the Ubercart module are particularly at risk, as this vulnerability can be exploited without requiring special privileges beyond basic user accounts. The exploitability of this issue increases significantly when multiple users share the same system, as attackers can potentially access keys belonging to other users within the same platform environment.
The recommended mitigation strategy involves immediate upgrading to version 6.x-1.1 or later of the Ubercart Product Keys module, which includes proper access control checks. System administrators should also implement additional monitoring of key access patterns and consider implementing network-level restrictions for sensitive administrative functions. Security teams should conduct thorough vulnerability assessments of all Drupal installations to identify similar access control issues within other contributed modules. Organizations may also consider implementing additional security measures such as rate limiting for key access requests and enhanced logging to detect potential exploitation attempts. The vulnerability demonstrates the critical importance of proper access control implementation in web applications and highlights the need for continuous security auditing of third-party modules in content management systems.
