The CVE-2013-5937 vulnerability represents a critical cross-site request forgery flaw within the Click2Sell Suite module version 6.x-1.x for Drupal platforms. This vulnerability specifically targets the Drupal Form API and enables malicious actors to exploit administrative sessions through crafted requests that result in unauthorized database deletions. The flaw resides in the module's insufficient validation mechanisms that fail to properly verify the authenticity of requests originating from legitimate administrative users. Attackers can leverage this vulnerability by constructing malicious web pages or email attachments that, when visited by an authenticated administrator, automatically submit forged requests to the vulnerable Drupal installation.
The technical exploitation of this CSRF vulnerability occurs through manipulation of the Drupal Form API's inherent trust mechanisms. When administrators interact with the vulnerable module, the system does not adequately validate that incoming requests originate from legitimate sources within the same session context. This allows attackers to craft malicious payloads that, when executed through an administrator's browser session, perform unauthorized database operations. The vulnerability specifically affects the deletion functionality within the Click2Sell Suite module, making it particularly dangerous as it enables complete data destruction capabilities rather than merely data modification or theft.
The operational impact of this vulnerability extends beyond simple data loss, as it compromises the fundamental integrity and availability of Drupal-based systems using the affected module. Administrators who visit malicious sites or open compromised email attachments can unknowingly execute destructive operations on their databases, potentially leading to complete system compromise and data recovery challenges. The attack vector involves the exploitation of session management weaknesses within the Drupal framework, where the absence of proper CSRF tokens or referer validation allows attackers to hijack authenticated sessions. This vulnerability particularly affects organizations relying on Drupal for e-commerce or content management solutions where administrative database access is critical for business operations.
Mitigation strategies for CVE-2013-5937 should prioritize immediate module updates and patches provided by Drupal security teams, as the vulnerability affects a specific version of the Click2Sell Suite module. Organizations should implement comprehensive CSRF protection mechanisms including the use of anti-CSRF tokens within all administrative forms and ensure proper validation of request origins through referer headers and origin checks. The vulnerability aligns with CWE-352, which specifically addresses cross-site request forgery weaknesses in web applications, and maps to ATT&CK technique T1078.004 related to valid accounts and credential access. Additionally, implementing web application firewalls with CSRF detection capabilities and conducting regular security audits of Drupal modules can help prevent exploitation of similar vulnerabilities in the future. Organizations should also establish robust monitoring procedures to detect unauthorized administrative database operations and maintain comprehensive backup strategies to ensure rapid recovery from potential exploitation incidents.
