CVE-2009-4515 in Storm
Summary
by MITRE
The Storm module 6.x before 6.x-1.25 for Drupal does not enforce privilege requirements for storminvoiceitem nodes, which allows remote attackers to read node titles via unspecified vectors.

The vulnerability identified as CVE-2009-4515 affects the Storm module version 6.x prior to 6.x-1.25 within the Drupal content management system ecosystem. This represents a critical access control flaw that undermines the security model of the affected platform. The Storm module serves as a commerce solution for Drupal installations, managing various e-commerce functionalities including invoice items and related transactions. The vulnerability specifically targets the storminvoiceitem node type, which contains sensitive commercial data that should be restricted to authorized personnel only.
The technical flaw stems from insufficient privilege enforcement within the module's access control mechanisms. When processing requests for storminvoiceitem nodes, the system fails to properly validate user permissions before allowing data retrieval operations. This weakness creates an unauthorized information disclosure scenario where remote attackers can exploit unspecified vectors to access node titles without proper authentication. The vulnerability operates at the application layer, specifically targeting the module's node access controls rather than underlying system vulnerabilities. According to CWE classification, this corresponds to CWE-285: Improper Authorization, which encompasses situations where the application fails to properly enforce access restrictions on protected resources.
The operational impact of this vulnerability extends beyond simple information disclosure, as node titles may contain sensitive commercial information including product names, service descriptions, pricing details, and customer transaction data. Attackers could potentially gather intelligence about business operations, pricing strategies, and customer bases through systematic enumeration of these unprotected nodes. The remote nature of the attack vector means that threat actors do not require physical access or local network presence to exploit this vulnerability, making it particularly dangerous for publicly accessible Drupal installations. This weakness could enable reconnaissance activities that support more sophisticated attacks or provide competitive intelligence to malicious actors.
Organizations using vulnerable Drupal installations should prioritize immediate patching to address this security gap. The recommended mitigation involves upgrading to Storm module version 6.x-1.25 or later, which contains the necessary access control fixes. Additionally, system administrators should implement network-level controls including firewall rules to restrict access to administrative interfaces and consider implementing additional monitoring for unusual node access patterns. From an ATT&CK framework perspective, this vulnerability aligns with techniques involving privilege escalation and credential harvesting through information gathering activities. The vulnerability also demonstrates the importance of proper input validation and access control implementation in web applications, particularly in commerce-focused modules that handle sensitive business data. Organizations should conduct comprehensive security assessments to identify similar privilege enforcement issues in other modules and ensure that all user interactions with protected resources are properly authenticated and authorized.
