CVE-2012-2069 in Wishlist
Summary
by MITRE
Cross-site request forgery (CSRF) vulnerability in the Wishlist module 6.x-2.x before 6.x-2.6 and 7.x-2.x before 7.x-2.6 for Drupal allows remote attackers to hijack the authentication of arbitrary users for requests that insert cross-site scripting (XSS) sequences via the (1) wl_reveal or (2) q parameters.

The CVE-2012-2069 vulnerability represents a critical cross-site request forgery flaw within the Wishlist module for Drupal platforms, specifically affecting versions 6.x-2.x prior to 6.x-2.6 and 7.x-2.x prior to 7.x-2.6. This vulnerability operates at the intersection of CSRF and XSS attack vectors, creating a particularly dangerous exploitation scenario for malicious actors targeting Drupal-based web applications. The flaw manifests through two distinct parameter pathways: wl_reveal and q, both of which can be manipulated to inject malicious cross-site scripting sequences into the target system.
The technical exploitation of this vulnerability occurs when an attacker crafts malicious requests that leverage the CSRF mechanism to hijack authenticated sessions of arbitrary users within the Drupal environment. When users interact with the vulnerable Wishlist module, the malicious requests can be executed without their knowledge or consent, particularly when they visit compromised web pages or click on malicious links. The vulnerability specifically affects the module's handling of user input through the wl_reveal and q parameters, which are processed without proper validation or anti-CSRF token verification. This allows attackers to inject XSS payloads that can execute within the context of authenticated user sessions, potentially leading to complete account compromise and unauthorized access to sensitive functionality.
From an operational impact perspective, this vulnerability presents significant risks to Drupal websites that utilize the Wishlist module, as it enables attackers to perform unauthorized actions on behalf of authenticated users. The combined CSRF-XSS nature of the flaw means that successful exploitation could result in persistent XSS attacks, session hijacking, and potential data exfiltration. Attackers could leverage this vulnerability to escalate privileges, access user accounts, modify content, or even establish backdoor access to the entire Drupal installation. The impact extends beyond individual user sessions to potentially compromise the entire web application, especially when combined with other vulnerabilities or when the affected Drupal site has elevated user privileges.
Security professionals should recognize this vulnerability as a variant of CWE-352, which specifically addresses cross-site request forgery weaknesses in web applications. The exploitation pattern aligns with ATT&CK technique T1566.001, which covers credential access through social engineering attacks that manipulate web browsers into executing unauthorized commands. Mitigation strategies should include immediate patching of the Wishlist module to versions 6.x-2.6 or 7.x-2.6 respectively, along with implementing proper input validation and CSRF token mechanisms within the module's codebase. Organizations should also consider implementing additional security measures such as Content Security Policy headers, regular security audits of third-party modules, and monitoring for suspicious user activity patterns that might indicate exploitation attempts. The vulnerability underscores the importance of maintaining up-to-date security patches for all Drupal modules, as even seemingly minor components can provide attackers with significant footholds within web applications.
