CVE-2008-6758 in Shop
Summary
by MITRE
Cross-site request forgery (CSRF) vulnerability in cart_save.php in ViArt Shop (aka Shopping Cart) 3.5 allows remote attackers to hijack the authentication of arbitrary users for requests that conduct persistent cross-site scripting (XSS) attacks via the cart_name parameter in a save action.

The CVE-2008-6758 vulnerability represents a critical cross-site request forgery flaw within the ViArt Shop e-commerce platform version 3.5, specifically affecting the cart_save.php component. This vulnerability operates at the intersection of CSRF and XSS attack vectors, creating a particularly dangerous exploitation scenario where attackers can leverage CSRF mechanisms to execute persistent XSS payloads against authenticated users. The flaw manifests through the cart_name parameter during save operations, allowing remote adversaries to manipulate session authentication tokens and inject malicious scripts that persist within the application's cart functionality.
The technical implementation of this vulnerability stems from insufficient validation and token verification mechanisms within the cart_save.php script. When users perform cart save operations, the application fails to properly validate the authenticity of requests originating from legitimate users, creating an opportunity for attackers to craft malicious requests that appear to come from authenticated sessions. The vulnerability specifically targets the cart_name parameter, which serves as an entry point for attackers to inject malicious payloads that can execute within the context of other users' sessions. This design flaw enables attackers to bypass standard CSRF protection measures that typically validate request origins and user authentication states.
The operational impact of CVE-2008-6758 extends beyond simple session hijacking to encompass persistent XSS attacks that can compromise user data and system integrity. Once exploited, attackers can inject malicious scripts that execute whenever affected users view their shopping carts, potentially stealing session cookies, redirecting users to malicious sites, or performing unauthorized transactions. The persistent nature of these XSS payloads means that the malicious code remains active within the application's cart functionality, continuously affecting any user who accesses their saved cart information. This creates a sustained threat vector that can compromise multiple users over time without requiring repeated exploitation attempts.
Security professionals should recognize this vulnerability as a composite threat that aligns with CWE-352 (Cross-Site Request Forgery) and CWE-79 (Cross-Site Scripting) categories, representing a sophisticated attack pattern that combines multiple exploitation techniques. The vulnerability also maps to ATT&CK technique T1531 (Account Access Removal) and T1059.007 (Command and Scripting Interpreter: PowerShell) through its potential for session hijacking and persistent payload execution. Organizations using ViArt Shop 3.5 should implement comprehensive mitigation strategies including proper CSRF token implementation, input validation for cart_name parameters, and regular security audits of session management mechanisms. Additionally, the vulnerability demonstrates the importance of maintaining up-to-date e-commerce platforms and implementing proper security controls to prevent attackers from chaining multiple exploitation techniques against single application components.
The remediation approach for CVE-2008-6758 requires immediate implementation of robust CSRF protection mechanisms that validate request authenticity through unique tokens generated for each user session. The cart_save.php script must be modified to verify that all cart saving operations originate from legitimate authenticated users through proper token validation rather than relying solely on session state. Input sanitization of the cart_name parameter should be implemented to prevent malicious script injection, while the application should enforce strict validation of all user-supplied data. Organizations should also consider implementing additional security measures such as Content Security Policy headers to mitigate the impact of any potential XSS payloads that might still be executed despite CSRF protections. Regular security testing and vulnerability assessments should be conducted to ensure that similar vulnerabilities do not exist in other application components that might be susceptible to similar exploitation patterns.
