CVE-2025-2378 Overview
A SQL injection vulnerability has been identified in PHPGurukul Medical Card Generation System version 1.0. The vulnerability exists in the /download-medical-cards.php file where the searchdata parameter is susceptible to SQL injection attacks due to improper input sanitization. This flaw allows remote attackers to execute arbitrary SQL commands against the backend database, potentially compromising sensitive medical card data and patient information.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete sensitive medical card data from the database without authentication, potentially exposing patient personal health information.
Affected Products
- PHPGurukul Medical Card Generation System 1.0
- Applications using the vulnerable /download-medical-cards.php endpoint
- Systems with the searchdata parameter exposed to user input

Technical Details for CVE-2025-2378
Vulnerability Analysis
This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the Medical Card Generation System's search functionality. The vulnerability is network-accessible, requiring no authentication or user interaction to exploit. When an attacker supplies malicious input through the searchdata parameter, the application fails to properly sanitize or parameterize the input before incorporating it into SQL queries, allowing the injected SQL commands to execute directly against the database.
The exploitation of this vulnerability could lead to unauthorized access to the medical card database, enabling attackers to retrieve sensitive patient information, modify existing records, or potentially escalate their access within the system. The exploit has been publicly disclosed, increasing the risk of active exploitation in the wild.
Root Cause
The root cause of this vulnerability is the lack of proper input validation and parameterized queries in the /download-medical-cards.php file. The application directly concatenates user-supplied input from the searchdata parameter into SQL queries without sanitization, allowing attackers to break out of the intended query structure and inject arbitrary SQL commands.
Attack Vector
The attack vector is network-based, allowing remote exploitation without authentication. An attacker can craft malicious HTTP requests targeting the /download-medical-cards.php endpoint with specially crafted searchdata parameter values containing SQL injection payloads.
The vulnerability manifests in the search functionality where user input is processed. Attackers can manipulate the searchdata parameter to inject SQL commands that modify the query's logic. Typical exploitation techniques include union-based injection to extract data from other tables, boolean-based blind injection to enumerate database contents, and time-based blind injection for systems where direct output is not visible. For detailed technical information, see the GitHub Issue Discussion and VulDB #299877.
Detection Methods for CVE-2025-2378
Indicators of Compromise
- Unusual or malformed requests to /download-medical-cards.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
- Database error messages appearing in application logs or responses that reveal SQL query structure
- Unexpected database queries or data access patterns in database audit logs
- Evidence of data exfiltration or unauthorized bulk data retrieval from medical card tables
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block common SQL injection patterns in the searchdata parameter
- Monitor HTTP request logs for suspicious characters and SQL keywords in query parameters targeting the affected endpoint
- Enable database query logging and audit for unusual SELECT, UNION, or data extraction operations
- Deploy intrusion detection systems with signatures for SQL injection attack patterns
Monitoring Recommendations
- Configure real-time alerting for any requests to /download-medical-cards.php containing SQL metacharacters
- Review database access logs regularly for queries that deviate from normal application behavior
- Monitor for increased error rates or unusual response sizes from the affected endpoint
- Implement application performance monitoring to detect anomalous database query execution times indicative of time-based SQL injection
How to Mitigate CVE-2025-2378
Immediate Actions Required
- Restrict access to the /download-medical-cards.php endpoint using network-level controls or authentication until a patch is available
- Deploy web application firewall rules to filter SQL injection attempts targeting the searchdata parameter
- Review and audit the codebase for similar SQL injection vulnerabilities in other endpoints
- Consider taking the affected functionality offline if it handles critical medical data
Patch Information
As of the last update on 2025-04-02, no official vendor patch has been released for this vulnerability. Organizations should monitor the PHP Gurukul Security Resource for security updates. In the interim, implementing the workarounds below is strongly recommended.
Workarounds
- Implement prepared statements with parameterized queries in the affected PHP code to prevent SQL injection
- Add server-side input validation to whitelist acceptable characters and reject SQL metacharacters in the searchdata parameter
- Deploy a web application firewall configured with SQL injection detection rules in front of the application
- Implement rate limiting on the affected endpoint to slow potential automated exploitation attempts
- Apply the principle of least privilege to the database user account used by the application to limit potential damage
# Example Apache mod_rewrite rule to block suspicious requests
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|update|delete|drop|alter|truncate|exec|xp_) [NC]
RewriteRule ^download-medical-cards\.php$ - [F,L]
