CVE-2009-4729 in Adult Script
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in x10 Adult Media Script 1.7 allow remote attackers to inject arbitrary web script or HTML via the (1) pic_id parameter to includes/video_ad.php, (2) category parameter to linkvideos_listing.php, (3) id parameter to templates/header1.php, and (4) key parameter to video_listing.php.

The CVE-2009-4729 vulnerability represents a critical cross-site scripting flaw affecting the x10 Adult Media Script version 1.7, a content management system designed for adult-oriented media hosting platforms. This vulnerability manifests through four distinct attack vectors that collectively expose the application to remote code execution through malicious script injection. The flaw resides in the application's insufficient input validation and output sanitization mechanisms, allowing attackers to inject malicious payloads through carefully crafted parameters that are then executed within the context of other users' browsers. The vulnerability affects multiple core components of the media script, including video advertisement handling, category navigation, header template rendering, and video listing functionality, creating multiple entry points for exploitation.
The technical exploitation of this vulnerability follows the standard XSS attack pattern where malicious input is not properly escaped or validated before being rendered in web pages. When an attacker submits malicious content through the pic_id parameter in includes/video_ad.php, the application fails to sanitize the input, allowing script tags or JavaScript code to be executed when other users view the affected video advertisement. Similarly, the category parameter in linkvideos_listing.php, the id parameter in templates/header1.php, and the key parameter in video_listing.php all suffer from the same fundamental flaw where user-supplied data is directly incorporated into dynamic web content without proper security controls. This vulnerability directly maps to CWE-79, which specifically addresses Cross-Site Scripting flaws in web applications, and represents a classic example of insecure input handling that violates fundamental web security principles.
The operational impact of CVE-2009-4729 extends beyond simple script injection, as it enables attackers to perform session hijacking, steal user credentials, redirect victims to malicious sites, and potentially gain unauthorized access to administrative functions. The vulnerability's presence in header template files particularly concerning, as it could allow attackers to inject malicious code that persists across multiple page views and user sessions. Additionally, the exposure in video listing and advertisement components means that any user visiting affected pages could become compromised, creating a widespread attack surface that could affect thousands of users depending on the platform's traffic. The vulnerability's persistence across multiple file types indicates a systemic failure in the application's security architecture, suggesting that input validation controls were not consistently implemented throughout the codebase.
Mitigation strategies for this vulnerability must address the root cause through comprehensive input sanitization and output encoding mechanisms. The primary remediation involves implementing strict parameter validation and sanitization for all user-supplied inputs, particularly those used in dynamic content generation. Organizations should implement proper HTML entity encoding when rendering user data in web pages, ensuring that special characters are properly escaped to prevent script execution. The solution should include input validation at multiple layers, including server-side validation, parameter filtering, and output encoding to prevent XSS attacks from propagating through the system. Security controls should follow established frameworks such as the OWASP Top Ten and ATT&CK framework methodologies for preventing web-based attacks, specifically targeting the execution of malicious scripts through parameter manipulation. The implementation of Content Security Policy headers and proper session management controls would further strengthen defenses against exploitation attempts, while regular security audits and penetration testing should be conducted to identify similar vulnerabilities in the application's codebase and prevent future incidents.
