CVE-2025-7609 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Simple Shopping Cart application. The vulnerability exists in the /register.php file, specifically in the handling of the 'ruser_email' parameter. An attacker can remotely exploit this flaw by manipulating the 'ruser_email' argument, which is improperly sanitized, allowing malicious SQL code to be injected into the backend database query. This injection can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the affected system's data. The vulnerability requires no authentication or user interaction, making it accessible for remote exploitation. Although the CVSS 4.0 base score is 6.9, categorizing it as medium severity, the potential impact of SQL injection vulnerabilities often depends on the database's role and the data it holds. The vulnerability has been publicly disclosed, but no known exploits have been observed in the wild yet. The lack of available patches or fixes at the time of disclosure increases the risk for organizations still running the affected version. Given that Simple Shopping Cart is an e-commerce solution, exploitation could lead to exposure of sensitive customer data, financial information, or allow attackers to manipulate transactions or user accounts.

For European organizations using code-projects Simple Shopping Cart 1.0, this vulnerability poses a significant risk to customer data privacy and business operations. Exploitation could result in unauthorized access to personal identifiable information (PII), including customer emails and potentially other sensitive data stored in the database. This could lead to regulatory non-compliance issues under GDPR, resulting in legal penalties and reputational damage. Additionally, attackers might alter or delete transaction records, impacting business integrity and causing financial losses. The remote and unauthenticated nature of the attack vector increases the likelihood of exploitation, especially for organizations that have not applied mitigations or upgraded their software. The absence of known exploits in the wild currently provides a limited window for proactive defense, but the public disclosure means threat actors could develop exploits rapidly. The impact extends beyond data breach to potential service disruption if attackers manipulate database availability or integrity.

European organizations should immediately assess their exposure to code-projects Simple Shopping Cart version 1.0. Specific mitigation steps include: 1) Upgrading to a patched or newer version of the Simple Shopping Cart software once available from the vendor. 2) If an upgrade is not immediately possible, implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 'ruser_email' parameter in /register.php. 3) Conduct thorough input validation and sanitization on all user-supplied data, especially email fields, to prevent injection. 4) Employ parameterized queries or prepared statements in the application code to eliminate direct concatenation of user inputs into SQL commands. 5) Monitor application logs and database activity for unusual queries or access patterns indicative of exploitation attempts. 6) Restrict database user privileges to the minimum necessary to limit the impact of a successful injection. 7) Conduct security awareness training for developers and administrators on secure coding practices and vulnerability management. 8) Regularly scan web applications with automated tools to detect injection vulnerabilities proactively.
