CVE-2025-5856 Overview
A SQL injection vulnerability has been identified in PHPGurukul BP Monitoring Management System version 1.0. This vulnerability exists in the /registration.php file, where the emailid parameter is not properly sanitized before being used in SQL queries. Attackers can exploit this flaw remotely to inject malicious SQL statements, potentially allowing unauthorized access to sensitive database information, data manipulation, or authentication bypass.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability without authentication to compromise the database integrity, extract sensitive patient health monitoring data, or potentially gain administrative access to the system.
Affected Products
- PHPGurukul BP Monitoring Management System 1.0
- Applications using the vulnerable /registration.php endpoint

Technical Details for CVE-2025-5856
Vulnerability Analysis
This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) occurs in the registration functionality of the BP Monitoring Management System. The application fails to properly validate and sanitize user-supplied input in the emailid parameter before incorporating it into SQL queries.
The vulnerability is network-accessible, requiring no authentication or user interaction to exploit. Successful exploitation can lead to unauthorized data disclosure, data modification, and potential system availability impacts. The exploit has been publicly disclosed, increasing the urgency for remediation.
Root Cause
The root cause is improper input validation in the /registration.php file. The application directly concatenates user input from the emailid parameter into SQL queries without using parameterized queries or prepared statements. This allows attackers to break out of the intended SQL context and inject arbitrary SQL commands.
Attack Vector
The attack can be initiated remotely over the network. An attacker can craft malicious HTTP requests containing SQL injection payloads in the emailid parameter during the registration process. The vulnerability requires no authentication and no user interaction, making it highly accessible to potential attackers.
The attack involves submitting specially crafted input through the email ID field that contains SQL metacharacters and commands. When the application processes this input without proper sanitization, the malicious SQL code executes against the backend database, potentially exposing all stored records including patient health monitoring data.

Detection Methods for CVE-2025-5856
Indicators of Compromise
- Unusual database queries or errors in application logs associated with /registration.php
- HTTP requests to /registration.php containing SQL metacharacters such as single quotes, double dashes, or UNION SELECT statements in the emailid parameter
- Unexpected database access patterns or bulk data extraction from the BP Monitoring Management System
- Failed or abnormal registration attempts with malformed email addresses
Detection Strategies
- Deploy web application firewalls (WAF) with SQL injection detection rules targeting the /registration.php endpoint
- Implement database activity monitoring to detect anomalous query patterns
- Configure intrusion detection systems to alert on common SQL injection payloads in HTTP POST requests
- Review web server access logs for requests containing suspicious characters in form parameters
Monitoring Recommendations
- Enable verbose logging for the PHP application and database server
- Monitor for database error messages that may indicate injection attempts
- Set up alerts for multiple failed registration attempts from the same IP address
- Track database query execution times for anomalies that may indicate time-based blind SQL injection attacks
How to Mitigate CVE-2025-5856
Immediate Actions Required
- Restrict network access to the BP Monitoring Management System to trusted IP ranges only
- Implement a web application firewall with SQL injection protection rules
- Consider temporarily disabling the registration functionality if not critical to operations
- Review database logs for evidence of prior exploitation attempts
Patch Information
As of the last update on June 10, 2025, no official vendor patch has been released for this vulnerability. Organizations should monitor the PHPGurukul website for security updates and consider implementing workarounds until an official fix is available.
Workarounds
- Modify the /registration.php file to use prepared statements with parameterized queries for all database operations
- Implement server-side input validation to sanitize the emailid parameter, rejecting input containing SQL metacharacters
- Deploy a reverse proxy or WAF to filter malicious requests before they reach the application
- Restrict database user permissions to limit the potential impact of successful SQL injection attacks
- Consider using a PHP framework with built-in SQL injection protection for handling database operations
# Example WAF rule for ModSecurity to block SQL injection attempts
SecRule ARGS:emailid "@rx (?i)(union|select|insert|update|delete|drop|--|;|'|\")" \
"id:100001,phase:2,deny,status:403,log,msg:'SQL Injection attempt blocked in emailid parameter'"
