CVE-2006-4964 in Md-pro
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in MAXdev MDPro 1.0.76 before 20060918 allows remote attackers to inject arbitrary web script or HTML via (1) vectors that bypass the XSS protection mechanisms of the pnVarCleanFromInput function, and (2) unspecified vectors related to the AntiCracker.

The CVE-2006-4964 vulnerability represents a critical cross-site scripting flaw in MAXdev MDPro version 1.0.76 and earlier releases, specifically before the 20060918 patch. This vulnerability exists within the application's input validation and sanitization mechanisms, creating a significant security risk for users of the software. The flaw allows remote attackers to execute malicious scripts in the context of other users' browsers, potentially leading to session hijacking, data theft, or unauthorized actions within the application's security boundaries. The vulnerability is particularly concerning as it affects a widely used content management system that handles sensitive user data and administrative functions.
The technical implementation of this XSS vulnerability occurs through two distinct attack vectors that bypass existing security protections. The first vector exploits weaknesses in the pnVarCleanFromInput function, which is designed to sanitize user input but fails to properly filter malicious content. This function serves as a primary defense mechanism against XSS attacks, yet the flaw allows attackers to craft inputs that slip through these protections. The second vector involves unspecified vulnerabilities related to the AntiCracker component, suggesting that the application's anti-piracy mechanisms may have been implemented without proper security considerations, creating additional attack surfaces. Both vectors demonstrate a fundamental flaw in the application's security architecture where input validation is insufficient to prevent malicious code execution.
The operational impact of this vulnerability extends beyond simple script execution, as it can enable sophisticated attacks that compromise user sessions and potentially escalate to full system compromise. Attackers can leverage these XSS flaws to steal session cookies, redirect users to malicious sites, deface web pages, or inject malicious content that persists across user sessions. The vulnerability affects not just individual users but the entire application ecosystem, as compromised user sessions can provide attackers with elevated privileges within the MDPro system. The timeframe of the vulnerability, existing before the 20060918 patch, indicates a prolonged exposure period that likely allowed multiple exploitation attempts and potential data breaches.
From a cybersecurity framework perspective, this vulnerability aligns with CWE-79, which describes Cross-site Scripting flaws in web applications. The weakness demonstrates poor input validation practices that violate fundamental security principles outlined in the OWASP Top Ten and NIST cybersecurity guidelines. The vulnerability also relates to ATT&CK technique T1566, specifically the use of malicious web content to compromise systems. Organizations using affected versions should implement immediate mitigations including input sanitization, output encoding, and proper security headers. The incident highlights the importance of comprehensive security testing, particularly for components that handle user input and implement anti-piracy measures, as these features can inadvertently introduce security weaknesses that attackers can exploit. Remediation efforts must include updating to patched versions, implementing proper input validation across all application components, and conducting thorough security assessments to identify similar vulnerabilities in other system components.
