CVE-2006-5631 in iG Shop
Summary
by MITRE
Cross-site scripting (XSS) vulnerability in change_pass.php in iG Shop 1.4 allows remote attackers to inject arbitrary web script or HTML via arbitrary query strings when the action parameter is not "1", as demonstrated using script in the action parameter, a different vulnerability than CVE-2006-5632.

The vulnerability described in CVE-2006-5631 represents a classic cross-site scripting flaw within the iG Shop 1.4 e-commerce platform, specifically manifesting in the change_pass.php script. This vulnerability operates under the Common Weakness Enumeration classification of CWE-79, which encompasses improper neutralization of input during web page generation, making it a fundamental web application security weakness. The flaw occurs when the application fails to properly sanitize user-supplied input parameters, particularly the action parameter, creating an avenue for malicious actors to execute unauthorized scripts within the context of other users' browsers.
The technical mechanism of this XSS vulnerability exploits the application's handling of query string parameters in the change_pass.php file. When the action parameter does not equal "1", the system processes the input without adequate sanitization or output encoding, allowing attackers to inject malicious JavaScript code or HTML content. This specific exploitation technique demonstrates a lack of proper input validation and context-specific output encoding, which are core defensive measures against XSS attacks. The vulnerability operates at the application layer, specifically targeting the web server's response handling to user requests containing malicious payloads.
The operational impact of this vulnerability extends beyond simple data theft or defacement, as it enables attackers to execute arbitrary code in the browsers of authenticated users. This creates a significant risk for e-commerce environments where users may have elevated privileges or access to sensitive customer data. Attackers can leverage this vulnerability to steal session cookies, redirect users to malicious sites, or modify the functionality of the web application. The attack surface is particularly concerning in the context of iG Shop, where users may be performing sensitive operations like password changes, potentially allowing for account takeover or privilege escalation attacks.
Mitigation strategies for this vulnerability should focus on implementing comprehensive input validation and output encoding mechanisms. The most effective approach involves sanitizing all user-supplied input parameters before processing or displaying them within web pages, specifically implementing proper context-aware output encoding for HTML, JavaScript, and URL contexts. Organizations should implement a robust secure coding practice that includes parameterized queries, proper input validation, and output encoding to prevent such vulnerabilities from occurring. Additionally, implementing a web application firewall and conducting regular security code reviews can help identify and remediate similar issues before they can be exploited in production environments. The vulnerability also highlights the importance of following the principle of least privilege and implementing proper session management controls to limit the potential damage from successful exploitation attempts.
