CVE-2006-6871 in eNdonesia
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in eNdonesia 8.4 allow remote attackers to inject arbitrary web script or HTML via (1) the mod parameter in a viewlink operation in mod.php, (2) the intypeid parameter in a showinfo operation in the informasi module in mod.php, (3) the "your Friend" field in friend.php, or (4) the "Main Text" field in admin.php.

The CVE-2006-6871 vulnerability represents a critical cross-site scripting flaw in the eNdonesia 8.4 content management system that exposes multiple attack vectors allowing remote code execution through malicious script injection. This vulnerability classifies under CWE-79 Improper Neutralization of Input During Web Page Generation, which specifically addresses the failure to properly sanitize user inputs before incorporating them into web page content. The flaw exists in the web application's input validation mechanisms, creating persistent security gaps that enable attackers to inject malicious scripts into web pages viewed by other users.
The vulnerability manifests through four distinct entry points within the application's codebase, each representing a separate injection point that could be exploited by remote attackers without authentication. The first vector involves the mod parameter within the viewlink operation in mod.php, where user-supplied input is directly incorporated into dynamic page generation without proper sanitization. The second vulnerability occurs in the informasi module's showinfo operation, specifically targeting the intypeid parameter, demonstrating a pattern of insufficient input validation across different modules. The third and fourth attack vectors involve the "your Friend" field in friend.php and the "Main Text" field in admin.php, respectively, showing that the vulnerability extends to both user-facing and administrative interfaces.
These XSS vulnerabilities create significant operational risks for affected systems, as they enable attackers to execute malicious scripts in the context of victim browsers, potentially leading to session hijacking, credential theft, and data exfiltration. The impact extends beyond simple script injection, as these flaws could be leveraged to perform actions on behalf of authenticated users, particularly in administrative contexts where the admin.php component is vulnerable. Attackers could craft malicious payloads that redirect users to phishing sites, steal session cookies, or even modify content on the affected website, depending on the privileges of the targeted users.
The exploitation of these vulnerabilities aligns with ATT&CK technique T1566.001 Validating and Evading Security Tools, as attackers can leverage these injection points to bypass security controls and establish persistent access to compromised systems. Organizations using eNdonesia 8.4 should implement immediate mitigations including input validation and output encoding for all user-supplied data, particularly in the identified parameter fields. The recommended approach involves implementing strict sanitization of all incoming data, employing Content Security Policy headers, and ensuring proper HTML escaping of dynamic content. Additionally, regular security audits and input validation testing should be conducted to identify similar vulnerabilities in other application components, as this flaw demonstrates a systemic issue with data handling practices across multiple modules.
The vulnerability highlights the critical importance of secure coding practices and input validation in web applications, particularly in content management systems that process user-generated content. Organizations should adopt comprehensive security measures including regular vulnerability assessments, security code reviews, and proper training for developers on secure programming practices. The widespread nature of XSS vulnerabilities in legacy systems like eNdonesia 8.4 demonstrates the need for continuous security maintenance and timely updates to address known vulnerabilities, as these flaws can remain exploitable for extended periods without proper remediation.
