The CVE-2009-1942 vulnerability represents a critical cross-site scripting flaw within the Quiz module for Drupal platforms, affecting versions 5.x, 6.x-2.x prior to 6.x-2.2, and 6.x-3.x prior to 6.x-3.0. This vulnerability specifically targets authenticated users who possess the privilege to create quizzes or quiz questions, creating a significant security risk for Drupal-based web applications that utilize this module. The flaw resides in the improper handling of user input during quiz creation processes, where malicious script code can be injected and subsequently executed in the browsers of other users who access the affected content.
The technical nature of this vulnerability aligns with CWE-79, which specifically addresses cross-site scripting flaws in web applications. The vulnerability manifests when authenticated users with sufficient privileges inject malicious code through unspecified vectors within the quiz creation interface. These vectors likely involve input fields where quiz questions or answers are stored, where the module fails to properly sanitize or escape user-provided content before rendering it in web pages. The vulnerability does not require special privileges beyond existing access rights, making it particularly dangerous as it can be exploited by insiders or compromised accounts with quiz creation capabilities.
The operational impact of this vulnerability extends beyond simple script injection, as it enables attackers to execute arbitrary web scripts and HTML content in the contexts of other users. This capability can lead to session hijacking, credential theft, data exfiltration, and the potential for further exploitation within the application. Attackers could craft malicious quiz questions that, when viewed by other users, would execute malicious code in their browsers, potentially leading to complete compromise of user sessions and access to sensitive application data. The vulnerability affects all users who can view quiz content, making the attack surface particularly broad within Drupal installations.
Mitigation strategies for CVE-2009-1942 should prioritize immediate patching of affected Drupal Quiz module versions to the latest secure releases. Organizations should implement proper input validation and output encoding mechanisms to prevent script injection, ensuring that all user-provided content undergoes sanitization before being rendered in web interfaces. The principle of least privilege should be enforced by carefully managing user permissions, limiting quiz creation capabilities to only trusted administrators. Additionally, implementing content security policies and regular security audits of Drupal modules can help identify and remediate similar vulnerabilities. This vulnerability demonstrates the importance of input sanitization in web applications and aligns with ATT&CK technique T1213, which covers data from information repositories, emphasizing the need for proper validation of user inputs in web-based applications.
