CVE-2025-51968 is a SQL Injection vulnerability identified in the action.php file of the PuneethReddyHC Online Shopping System Advanced version 1.0. The vulnerability arises because the application does not properly sanitize user-supplied input in the 'proId' POST parameter. This improper input validation allows an attacker to inject arbitrary SQL expressions into the backend database queries. SQL Injection vulnerabilities enable attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or deletion. In some cases, attackers can escalate privileges, bypass authentication, or execute administrative operations on the database. Since the vulnerability is located in a critical component handling product identification, exploitation could allow attackers to extract sensitive customer data, alter product information, or disrupt the e-commerce platform's normal operations. Although no known exploits are currently reported in the wild and no CVSS score has been assigned, the nature of SQL Injection vulnerabilities inherently poses a significant risk. The lack of a patch or mitigation details indicates that the vulnerability remains unaddressed, increasing the urgency for affected organizations to implement protective measures. The vulnerability's technical details confirm it was reserved in mid-2025 and published in August 2025, indicating it is a recent discovery.

For European organizations using the PuneethReddyHC Online Shopping System Advanced 1.0, this vulnerability could have severe consequences. Exploitation could lead to unauthorized disclosure of personal customer data, including payment and contact information, which would violate GDPR regulations and result in substantial fines and reputational damage. Data integrity could be compromised by unauthorized modification or deletion of product or transaction records, disrupting business operations and customer trust. Availability of the e-commerce platform could also be affected if attackers leverage the vulnerability to perform denial-of-service attacks or corrupt critical database tables. The potential for privilege escalation could allow attackers to gain administrative access to the backend systems, further exacerbating the impact. Given the critical role of e-commerce in European markets, such disruptions could have significant financial and operational repercussions. Additionally, the lack of known exploits suggests that organizations may not yet be actively defending against this threat, increasing the risk of successful attacks if the vulnerability becomes publicly exploited.

To mitigate this vulnerability, European organizations should immediately audit their use of the PuneethReddyHC Online Shopping System Advanced 1.0 and identify if the affected action.php file and the 'proId' POST parameter are in use. Since no official patch is currently available, organizations should implement the following specific measures: 1) Employ rigorous input validation and sanitization on all user-supplied data, especially the 'proId' parameter, using parameterized queries or prepared statements to prevent SQL Injection. 2) Conduct a comprehensive code review and penetration testing focused on SQL Injection vectors within the application. 3) Implement Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection attempts targeting the vulnerable parameter. 4) Monitor database logs and application logs for suspicious query patterns or repeated failed attempts to exploit the vulnerability. 5) Restrict database user privileges to the minimum necessary to limit the impact of any successful injection. 6) Plan for an urgent update or migration to a patched version once available from the vendor. 7) Educate development and security teams about secure coding practices to prevent similar vulnerabilities in the future.
