CVE-2011-0504 in VaM Shop
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in VaM Shop 1.6, 1.6.1, and probably earlier versions llow remote attackers to inject arbitrary web script or HTML via the (1) status parameter to admin/orders.php, (2) search parameter to admin/customers.php, or (3) STORE_NAME parameter to admin/configuration.php.

The vulnerability identified as CVE-2011-0504 represents a critical cross-site scripting weakness affecting VaM Shop versions 1.6, 1.6.1, and potentially earlier releases. This flaw resides in the administrative interface of the e-commerce platform, specifically within three distinct parameter handling mechanisms that fail to properly sanitize user input before rendering it in web responses. The vulnerability demonstrates a classic lack of input validation and output encoding that enables malicious actors to execute arbitrary scripts within the context of authenticated admin sessions.
The technical implementation of this vulnerability manifests through three separate attack vectors that exploit insufficient sanitization of user-supplied data. The first vector targets the status parameter in admin/orders.php, where unfiltered input allows attackers to inject malicious scripts that execute when administrators view order details. The second vulnerability exists in the search parameter of admin/customers.php, enabling attackers to inject XSS payloads when administrators perform customer searches. The third vector affects the STORE_NAME parameter in admin/configuration.php, where configuration values are not properly escaped before being displayed in administrative interfaces. These flaws collectively represent a failure in proper input validation and output encoding practices that directly violates security principles outlined in the OWASP Top Ten.
The operational impact of CVE-2011-0504 extends beyond simple script injection, as it provides attackers with potential access to administrative functions and sensitive customer data. When successful, these attacks can enable session hijacking, data exfiltration, and persistent backdoor installation within the administrative interface. Attackers can leverage these vulnerabilities to manipulate order statuses, access customer information, modify store configurations, and potentially escalate privileges within the compromised system. The vulnerability's presence in the administrative components means that successful exploitation could result in complete system compromise, particularly if attackers can maintain persistent access through the injected scripts.
Mitigation strategies for CVE-2011-0504 require immediate implementation of proper input validation and output encoding mechanisms throughout the affected application components. Organizations should implement strict parameter validation for all user-supplied inputs, particularly those used in administrative interfaces where privilege levels are elevated. The solution must include comprehensive sanitization of all parameters before rendering them in web responses, with particular attention to HTML escaping for dynamic content. Additionally, implementing Content Security Policy headers and adopting secure coding practices aligned with CWE-79 standards can significantly reduce the attack surface. Regular security audits and input validation testing should be conducted to prevent similar vulnerabilities from emerging in future releases, with the implementation of automated security scanning tools to detect potential XSS flaws in the codebase.
The vulnerability class represented by CVE-2011-0504 aligns with ATT&CK technique T1566.001 for initial access through malicious web content, and T1059.001 for command and scripting interpreter execution. The attack surface analysis reveals that this vulnerability operates within the application layer security context, where user input flows directly into web output without proper sanitization, making it particularly dangerous for applications handling sensitive administrative data. Organizations should consider implementing web application firewalls and input validation controls to prevent exploitation of these specific parameter injection points while maintaining the application's functionality.
