The vulnerability identified as CVE-2014-3737 represents a classic cross-site scripting flaw within the Lamp Design Storesprite e-commerce platform, specifically affecting versions prior to the 7-19-06-14 release. This vulnerability resides in the template file defaultheader.php and manifests when users interact with the currency selection dropdown functionality. The issue stems from inadequate input validation and output sanitization mechanisms that fail to properly handle malicious data injected through the PATH_INFO parameter directed to the brand.php script. The vulnerability operates at the application layer where user-supplied data flows through the currencyUrl function without appropriate sanitization measures, creating an exploitable condition that allows remote attackers to execute arbitrary web scripts or HTML code within the context of other users' browsers.
The technical exploitation of this vulnerability occurs through manipulation of the PATH_INFO parameter that gets processed by the currencyUrl function within the brand.php script. When users select different currency options from the dropdown menu, the application constructs URLs that incorporate user-supplied data without proper encoding or validation. This creates a pathway for attackers to inject malicious payloads that can be executed when other users browse to affected pages. The vulnerability specifically targets the default header template which is likely included across multiple pages, amplifying the potential impact. According to CWE-79, this vulnerability maps directly to Cross-Site Scripting, where the application fails to properly validate or encode output sent to web browsers, allowing attackers to inject client-side scripts.
The operational impact of CVE-2014-3737 extends beyond simple script injection, potentially enabling attackers to perform session hijacking, deface the website, steal sensitive user information, or redirect users to malicious sites. Since the vulnerability affects the currency selection functionality that is likely accessed frequently by users, the attack surface is considerable. The exploitation could lead to unauthorized access to user accounts, data theft, or compromise of the entire e-commerce platform. The vulnerability's persistence across multiple pages through the default header template means that a single injection could affect numerous user sessions and transactions. Organizations using this vulnerable software face significant risk of reputational damage and potential regulatory compliance violations under data protection standards such as gdpr and pci dss.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and output encoding mechanisms. The primary fix involves sanitizing all user-supplied data before it is processed or rendered in the currencyUrl function, specifically ensuring that PATH_INFO parameters are properly encoded before being incorporated into URLs. Organizations should implement Content Security Policy headers to limit script execution and employ proper parameter validation techniques. The solution aligns with ATT&CK technique T1059.001 for command and scripting interpreter, as attackers could leverage this vulnerability to execute malicious scripts. Additionally, upgrading to the patched version of Lamp Design Storesprite released after 7-19-06-14 represents the most effective long-term solution. Regular security audits and input validation testing should be implemented to prevent similar vulnerabilities in future development cycles, following secure coding practices recommended by owasp and nist guidelines.
