CVE-2025-51969 is a medium severity 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 a GET request. Specifically, the product_id parameter is directly incorporated into a SQL query without adequate sanitization or parameterization, allowing an attacker to inject malicious SQL code. This flaw corresponds to CWE-89, which covers improper neutralization of special elements in SQL commands. Exploiting this vulnerability does not require authentication or user interaction, and can be performed remotely over the network (AV:N). The CVSS 3.1 base score is 6.5, indicating a medium severity impact primarily affecting confidentiality and integrity, but not availability. Successful exploitation could allow an attacker to read unauthorized data from the database or modify data, potentially leading to data leakage or corruption. However, no known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability affects an unspecified version of the PuneethReddyHC Online Shopping System Advanced 1.0, which is an e-commerce platform. Given the nature of the vulnerability, it is likely exploitable by crafting malicious URLs targeting the product.php page with manipulated product_id parameters.

For European organizations using the PuneethReddyHC Online Shopping System Advanced 1.0, this vulnerability poses a risk of unauthorized data disclosure and data integrity compromise. E-commerce platforms typically handle sensitive customer information, including personal details and payment data. While the CVSS vector indicates no direct impact on availability, the confidentiality and integrity breaches could lead to exposure of customer data, loss of trust, and potential regulatory penalties under GDPR. Additionally, attackers could manipulate product information or pricing, causing financial and reputational damage. The lack of authentication requirement means attackers can exploit this vulnerability without credentials, increasing the risk of widespread attacks. Organizations in Europe must be vigilant, especially those relying on this specific shopping system or similar vulnerable components, as exploitation could facilitate further attacks or data breaches.

To mitigate this vulnerability, organizations should immediately implement input validation and parameterized queries (prepared statements) for the product_id parameter in the product.php page. Avoid directly embedding user input into SQL statements. Employ web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the product.php endpoint. Conduct thorough code reviews and security testing (including automated scanning and manual penetration testing) to identify and remediate similar injection flaws. Monitor web server logs for suspicious query strings containing SQL syntax or unusual characters. If possible, restrict access to the product.php page or implement rate limiting to reduce attack surface. Since no official patch is available, organizations should consider temporary compensating controls such as input filtering at the web server or application layer until a vendor patch is released. Finally, ensure regular backups of the database to enable recovery in case of data tampering.
