CVE-2025-51970 is a SQL Injection vulnerability identified in the action.php endpoint of the PuneethReddyHC Online Shopping System Advanced 1.0. The vulnerability arises due to improper sanitization of user-supplied input in the 'keyword' POST parameter. SQL Injection (SQLi) vulnerabilities allow attackers to manipulate backend SQL queries by injecting malicious input, potentially leading to unauthorized data access, data modification, or even full system compromise. In this case, the lack of input validation or parameterized queries in the 'keyword' parameter enables an attacker to craft malicious SQL statements that the database executes. This can result in unauthorized disclosure of sensitive customer data, manipulation of product listings, or disruption of the e-commerce platform's normal operations. Although no known exploits are currently reported in the wild, the vulnerability is publicly disclosed and could be targeted by attackers once exploit code becomes available. The absence of a CVSS score indicates that the vulnerability has not yet been fully assessed for severity, but the nature of SQL Injection typically represents a high-risk threat to affected systems. The PuneethReddyHC Online Shopping System Advanced 1.0 appears to be a niche or less widely known e-commerce platform, which may limit the immediate scope but does not reduce the potential impact on organizations using it.

For European organizations using the PuneethReddyHC Online Shopping System Advanced 1.0, this SQL Injection vulnerability poses significant risks. Exploitation could lead to unauthorized access to customer personal data, including payment information, violating GDPR requirements and resulting in regulatory penalties and reputational damage. Data integrity could be compromised, allowing attackers to alter product information or transaction records, undermining business operations and customer trust. Availability could also be affected if attackers execute destructive SQL commands or cause database crashes, leading to downtime and loss of sales. Given the e-commerce context, financial fraud and theft are also potential consequences. Even if the platform is not widely adopted, organizations relying on it for online sales in Europe must consider the legal and operational impacts of a breach. The vulnerability could also serve as a foothold for further network intrusion if attackers leverage compromised credentials or escalate privileges.

To mitigate this vulnerability, organizations should immediately review and update the action.php endpoint to implement proper input validation and sanitization for the 'keyword' POST parameter. The recommended approach is to use parameterized queries or prepared statements to prevent SQL Injection. Additionally, employing a web application firewall (WAF) with rules to detect and block SQL Injection attempts can provide an additional layer of defense. Organizations should also conduct a thorough security audit of the entire application to identify and remediate any other injection points. Regularly updating the e-commerce platform with security patches from the vendor is critical once available. Monitoring application logs for suspicious input patterns and failed SQL queries can help detect attempted exploitation. Finally, organizations should ensure that database accounts used by the application have the minimum necessary privileges to limit the impact of any successful injection.
