CVE-2007-6646 in LiveCart
Summary
by MITRE
Multiple cross-site scripting (XSS) vulnerabilities in LiveCart 1.0.1, and possibly other versions before 1.1.0, allow remote attackers to inject arbitrary web script or HTML via (1) the return parameter to user/remindPassword, (2) the q parameter to the category script, (3) the return parameter to the order script, or (4) the email parameter to user/remindComplete.

The vulnerability identified as CVE-2007-6646 represents a critical cross-site scripting flaw affecting LiveCart e-commerce software version 1.0.1 and potentially earlier versions up to 1.0.x. This vulnerability exposes the application to remote code execution through malicious web script injection, creating significant security risks for online retailers and their customers. The flaw manifests in four distinct attack vectors within the application's user authentication and product category browsing functionality, making it particularly dangerous due to its widespread impact across core application components.
The technical implementation of this vulnerability stems from inadequate input validation and output encoding within the LiveCart application's parameter handling mechanisms. Attackers can exploit these weaknesses by injecting malicious scripts through specific parameters including the return parameter in user/remindPassword, the q parameter in category scripts, the return parameter in order scripts, and the email parameter in user/remindComplete. These parameters are processed without proper sanitization, allowing attackers to execute arbitrary JavaScript code in the context of victim browsers. The vulnerability directly maps to CWE-79, which defines cross-site scripting as a weakness where untrusted data is embedded into web pages without proper validation or encoding, enabling malicious scripts to execute in user contexts.
The operational impact of this vulnerability extends beyond simple script injection, potentially enabling attackers to steal session cookies, perform unauthorized transactions, manipulate customer data, and conduct phishing attacks against legitimate users. When exploited, these XSS vulnerabilities can compromise user authentication, lead to account takeovers, and provide attackers with persistent access to customer information stored within the e-commerce platform. The attack vectors are particularly concerning because they target fundamental user interaction points including password recovery processes, product search functionality, and order management systems, which are frequently accessed by both legitimate users and potential attackers.
Security practitioners should implement comprehensive input validation and output encoding mechanisms to prevent this vulnerability from being exploited. The recommended mitigations include implementing strict parameter validation for all user-supplied inputs, applying proper HTML escaping before rendering dynamic content, and ensuring that all application components properly sanitize data before processing. Organizations should also consider implementing content security policies to limit script execution capabilities within the application environment. The vulnerability demonstrates the critical importance of input validation and output encoding practices as outlined in the OWASP Top Ten and aligns with ATT&CK technique T1566, which covers the exploitation of web application vulnerabilities for initial access and privilege escalation. Regular security audits and vulnerability assessments should be conducted to identify similar weaknesses in other web applications and ensure that proper security controls are maintained throughout the software development lifecycle.
