The vulnerability identified as CVE-2007-6320 affects the Feature module version 4.7.x-dev and 5.x-dev before the 20071206 release within the Drupal content management system. This issue represents a significant security flaw that undermines the fundamental security mechanisms designed to protect Drupal installations from unauthorized actions. The Feature module, which was intended to provide functionality for managing Drupal features, failed to properly implement the Forms API submission model that is central to Drupal's security architecture.
The technical flaw stems from the module's deviation from Drupal's established Forms API submission model, which is designed to prevent cross-site request forgery attacks by implementing proper validation mechanisms. When a module does not follow the standard Forms API submission model, it bypasses the built-in security checks that typically validate the authenticity of form submissions. This allows attackers to craft malicious requests that appear to originate from legitimate users within the Drupal system, effectively circumventing the CSRF protection mechanisms that should normally be in place.
The operational impact of this vulnerability is substantial as it enables remote attackers to perform unauthorized actions within Drupal installations that utilize the affected Feature module. Attackers can exploit this weakness to execute arbitrary commands, modify content, or manipulate user permissions without requiring authentication. The vulnerability particularly affects systems where the Feature module is enabled, making it a widespread concern across Drupal installations that had not yet updated to the patched version. This type of vulnerability directly violates the principles of authentication and authorization that form the foundation of web application security.
The vulnerability aligns with CWE-352, which specifically addresses Cross-Site Request Forgery, and represents a failure to implement proper input validation and request verification mechanisms. From an ATT&CK framework perspective, this vulnerability maps to the T1566.001 technique related to "Phishing with Spoofed Delivery" and potentially T1078.004 for "Valid Accounts: Cloud Accounts" if the CSRF attack results in unauthorized access to administrative functions. The lack of proper security implementation in the Forms API submission model creates an exploitable condition that directly enables privilege escalation and unauthorized system manipulation.
Organizations affected by this vulnerability should immediately update to the patched version of the Feature module released on or after December 6, 2007. The recommended mitigation strategy involves implementing proper security patches and conducting thorough security reviews of all Drupal modules to ensure compliance with the Forms API submission model. System administrators should also consider implementing additional security controls such as web application firewalls and regular security audits to identify and remediate similar implementation flaws in other components. The vulnerability highlights the critical importance of following established security frameworks and standards when developing web application components to prevent the introduction of exploitable weaknesses into production systems.
