CVE-2025-11430 identifies a SQL injection vulnerability in SourceCodester Simple E-Commerce Bookstore version 1.0, located in the /cart.php file. The vulnerability arises from improper sanitization of the 'remove' parameter, which is susceptible to SQL injection attacks. An attacker can remotely manipulate this parameter to inject arbitrary SQL commands into the backend database query, potentially extracting sensitive data, modifying database contents, or causing denial of service by corrupting data or triggering errors. The vulnerability requires no authentication or user interaction, making it highly accessible to remote attackers. The CVSS 4.0 score of 6.9 (medium severity) reflects the network attack vector, low complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. Although no known exploits are currently active in the wild, the public availability of exploit code increases the likelihood of exploitation attempts. The lack of vendor patches or updates at this time necessitates immediate mitigation through secure coding practices and input validation. This vulnerability is particularly critical for e-commerce platforms handling customer data and transactions, as exploitation could lead to data breaches, fraudulent transactions, or service interruptions.

For European organizations, especially those operating small to medium-sized e-commerce platforms using SourceCodester Simple E-Commerce Bookstore 1.0, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of customer data, including personal and payment information, undermining GDPR compliance and resulting in legal and financial penalties. Data integrity could be compromised, allowing attackers to manipulate order data or inventory records, potentially causing financial loss and reputational damage. Availability impacts could arise if attackers disrupt database operations, leading to service outages and loss of customer trust. Given the medium severity, the threat is serious but not catastrophic; however, the ease of exploitation without authentication increases risk. Organizations in Europe with limited cybersecurity resources or lacking timely patch management processes are particularly vulnerable. The vulnerability also raises concerns about supply chain security if third-party developers or integrators use the affected software.

Organizations should immediately audit their use of SourceCodester Simple E-Commerce Bookstore version 1.0 and identify any instances of the vulnerable /cart.php file. Since no official patches are currently available, developers must implement input validation and sanitization on the 'remove' parameter, ideally replacing dynamic SQL queries with parameterized queries or prepared statements to prevent injection. Web application firewalls (WAFs) can be configured to detect and block SQL injection patterns targeting this parameter as a temporary protective measure. Regularly monitoring logs for suspicious database queries or unusual activity related to the cart functionality is recommended. Organizations should also consider upgrading to newer, secure versions of the software if available or migrating to alternative e-commerce platforms with better security track records. Additionally, conducting security awareness training for developers on secure coding practices and maintaining an incident response plan for potential exploitation events will enhance resilience.
