CVE-2025-51969 is a SQL Injection vulnerability identified in the product.php page of the PuneethReddyHC Online Shopping System Advanced 1.0. The vulnerability arises from improper validation of the product_id parameter passed via the GET method. This parameter is directly incorporated into a SQL query without adequate sanitization or use of parameterized queries, allowing an attacker to inject malicious SQL code. Exploiting this flaw could enable an attacker to manipulate the backend database queries, potentially leading to unauthorized data access, data modification, or even deletion. The lack of input validation means that crafted input could alter the intended SQL command structure, bypassing application logic and security controls. Although no known exploits are currently reported in the wild, the vulnerability's presence in an e-commerce platform makes it a significant risk, as attackers often target such systems for financial gain or data theft. The absence of a CVSS score limits precise severity quantification, but the nature of SQL Injection vulnerabilities typically implies a high risk due to their potential impact and ease of exploitation. No patches or mitigations have been officially published yet, and the affected version is specified as 1.0 without further detail on other versions. The vulnerability was reserved in June 2025 and published in August 2025, indicating recent discovery and disclosure.

For European organizations using the PuneethReddyHC Online Shopping System Advanced 1.0, this vulnerability poses a substantial threat to the confidentiality, integrity, and availability of their e-commerce platforms. Successful exploitation could lead to unauthorized disclosure of sensitive customer data, including personal and payment information, which would violate GDPR regulations and result in severe legal and financial penalties. Data integrity could be compromised by unauthorized modification or deletion of product or transaction records, disrupting business operations and damaging customer trust. Availability could also be affected if attackers execute destructive queries or cause database errors, leading to downtime and loss of revenue. Given the e-commerce context, the reputational damage from a breach could be significant, especially in competitive European markets where consumer trust is paramount. Furthermore, the lack of authentication requirements for exploiting this vulnerability increases the risk, as attackers do not need valid credentials to launch attacks. The absence of known exploits currently may provide a window for organizations to implement mitigations before active exploitation occurs.

European organizations should immediately audit their use of the PuneethReddyHC Online Shopping System Advanced 1.0 and identify any instances of the vulnerable product.php page. Since no official patches are available, organizations must implement immediate compensating controls. These include applying strict input validation and sanitization on the product_id parameter, preferably using parameterized queries or prepared statements to prevent SQL Injection. Web Application Firewalls (WAFs) should be configured to detect and block SQL Injection patterns targeting the product_id parameter. Organizations should conduct thorough code reviews and penetration testing focused on SQL Injection vulnerabilities across their e-commerce platforms. Additionally, monitoring database logs for unusual query patterns and setting up alerts for suspicious activities can help detect exploitation attempts early. If possible, upgrading or migrating to a more secure and actively maintained e-commerce platform should be considered. Finally, organizations must ensure compliance with GDPR by securing customer data and preparing incident response plans in case of a breach.
