CVE-2022-24746 is a medium-severity Cross-Site Scripting (XSS) vulnerability affecting the Shopware platform, an open commerce solution built on the Symfony PHP framework and Vue.js. The vulnerability arises from improper neutralization of user input during web page generation, specifically via the voucher code form. In affected versions prior to 6.4.8.1, attackers can inject malicious scripts into the voucher code input field, which are then rendered and executed in the context of the victim's browser. This can lead to theft of session cookies, user impersonation, defacement, or redirection to malicious sites. The issue is classified under CWE-79, indicating failure to properly sanitize or encode input before outputting it to the web page. The vulnerability was publicly disclosed on March 9, 2022, and has been patched in Shopware version 6.4.8.1. No known workarounds exist, and no exploits have been observed in the wild to date. The vulnerability requires no authentication but does require user interaction in the form of visiting a crafted page or submitting a malicious voucher code. Since Shopware is widely used by e-commerce businesses, the vulnerability poses a risk to both the platform operators and their customers, potentially enabling attackers to compromise user accounts or conduct phishing attacks within the trusted domain.

For European organizations, especially those operating e-commerce websites using Shopware versions prior to 6.4.8.1, this vulnerability can lead to significant reputational damage and financial loss. Successful exploitation could allow attackers to hijack user sessions, steal sensitive customer data, or manipulate transactions. This undermines customer trust and may lead to regulatory scrutiny under GDPR, particularly if personal data is compromised. The vulnerability also increases the risk of fraudulent activities and could be leveraged as a foothold for further attacks within the corporate network. Given the widespread adoption of Shopware in Europe, especially among small and medium-sized enterprises (SMEs) in retail and services sectors, the impact could be broad. The lack of known exploits reduces immediate risk, but the ease of exploitation and absence of workarounds mean that unpatched systems remain vulnerable to opportunistic attackers.

Organizations should immediately verify their Shopware platform version and upgrade to version 6.4.8.1 or later to apply the official patch. Since no workarounds exist, patching is the primary mitigation. Additionally, organizations should implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts, reducing the impact of potential XSS attacks. Web Application Firewalls (WAFs) can be configured with custom rules to detect and block suspicious input patterns targeting the voucher code form. Regular security audits and input validation reviews should be conducted to identify and remediate similar vulnerabilities proactively. User education on phishing risks and monitoring for unusual account activities can help detect exploitation attempts. Finally, logging and alerting mechanisms should be enhanced to capture anomalous voucher code submissions or script execution attempts.
