CVE-2025-4152 is a SQL Injection vulnerability identified in version 1.0 of the PHPGurukul Online Birth Certificate System, specifically within the /admin/bwdates-reports-details.php file. The vulnerability arises from improper sanitization of the 'fromdate' parameter, which is directly used in SQL queries without adequate validation or parameterization. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially manipulating the backend database. The injection can lead to unauthorized data access, data modification, or even deletion, compromising the confidentiality, integrity, and availability of the system's data. Given that the vulnerability does not require any authentication or user interaction, exploitation is straightforward. Although the CVSS 4.0 score is 6.9 (medium severity), the potential impact on sensitive personal data such as birth certificates elevates the risk profile. The disclosure is public, but no known exploits have been reported in the wild yet. The vulnerability may also affect other parameters beyond 'fromdate', indicating a broader input validation issue within the application. The system is likely used by governmental or municipal entities to manage vital records, making it a high-value target for attackers aiming to manipulate or steal personal identity information.

For European organizations, especially governmental agencies responsible for civil registration and vital statistics, this vulnerability poses a significant risk. Exploitation could lead to unauthorized access to sensitive personal data, including birth records, which are critical for identity verification, social services, and legal documentation. Data breaches could result in identity theft, fraud, and loss of public trust. Additionally, attackers could alter or delete records, disrupting administrative processes and potentially causing legal and operational challenges. The availability of the system could also be impacted if attackers execute destructive SQL commands. Given the centralized nature of birth certificate systems, a successful attack could have widespread effects across multiple regions or municipalities. Compliance with GDPR and other data protection regulations would be jeopardized, potentially leading to legal penalties and reputational damage.

1. Immediate application of input validation and parameterized queries (prepared statements) for all user-supplied inputs, especially the 'fromdate' parameter and any other parameters used in SQL queries. 2. Conduct a thorough code audit of the entire application to identify and remediate similar injection points beyond the reported parameter. 3. Implement Web Application Firewalls (WAF) with custom rules to detect and block SQL injection patterns targeting the affected endpoints. 4. Restrict database user privileges to the minimum necessary, avoiding use of highly privileged accounts for application database connections. 5. Monitor database logs and application logs for unusual query patterns or errors indicative of injection attempts. 6. Establish a patch management process to update the PHPGurukul Online Birth Certificate System once an official patch or update is released. 7. Consider network segmentation and access controls to limit exposure of the administrative interface to trusted networks only. 8. Educate system administrators and developers on secure coding practices and the importance of input sanitization. 9. If possible, deploy runtime application self-protection (RASP) tools to detect and prevent injection attacks in real time.
