CVE-2025-2736: PHPGurukul Old Age Home Management SQLI

CVE-2025-2736 Overview

A critical SQL injection vulnerability has been identified in PHPGurukul Old Age Home Management System version 1.0. The vulnerability exists in the /admin/bwdates-report-details.php file, where improper sanitization of the fromdate parameter allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without requiring authentication, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive resident and administrative data, modify database records, or potentially gain complete control over the underlying database server.

Affected Products

• PHPGurukul Old Age Home Management System 1.0
• Additional parameters in bwdates-report-details.php may also be affected

Technical Details for CVE-2025-2736

Vulnerability Analysis

This SQL injection vulnerability affects the date-based reporting functionality within the administrative panel of the Old Age Home Management System. The fromdate parameter in /admin/bwdates-report-details.php accepts user-supplied input that is directly incorporated into SQL queries without proper sanitization or parameterized query implementation. This allows attackers to craft malicious input that alters the intended SQL query logic, enabling unauthorized database operations.

The vulnerability is particularly concerning because it resides in the administrative section of the application, which typically handles sensitive resident information, financial records, and staff management data. Successful exploitation could expose personally identifiable information (PII) of elderly residents, medical records, and administrative credentials.

Root Cause

The root cause of CVE-2025-2736 is the failure to implement proper input validation and parameterized queries (prepared statements) when processing the fromdate parameter. The application directly concatenates user-supplied input into SQL query strings without escaping special characters or using database abstraction layers that prevent injection attacks. This is a classic example of CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Attack Vector

The attack can be launched remotely over the network without requiring any authentication or user interaction. An attacker can exploit this vulnerability by manipulating the fromdate parameter with specially crafted SQL injection payloads. The exploit has been publicly disclosed, increasing the likelihood of exploitation attempts in the wild.

The attack workflow typically involves:

1. Identifying the vulnerable endpoint at /admin/bwdates-report-details.php
2. Crafting SQL injection payloads targeting the fromdate parameter
3. Extracting database schema information using UNION-based or error-based injection techniques
4. Retrieving sensitive data including user credentials and resident information
5. Potentially escalating to operating system command execution depending on database configuration

Detection Methods for CVE-2025-2736

Indicators of Compromise

• Unusual or malformed date values in web server access logs for /admin/bwdates-report-details.php
• Database error messages indicating SQL syntax errors appearing in application logs
• Unexpected database queries containing SQL keywords like UNION, SELECT, OR 1=1, or comment sequences (--, #)
• Increased database load or unusual query patterns from the web application user account

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the fromdate parameter
• Implement database activity monitoring to detect anomalous query patterns and unauthorized data access attempts
• Enable detailed logging on both the web server and database server to capture suspicious requests
• Configure intrusion detection systems (IDS) to alert on SQL injection signature patterns targeting PHP applications

Monitoring Recommendations

• Monitor web server logs for requests to /admin/bwdates-report-details.php containing suspicious characters (single quotes, double dashes, semicolons)
• Set up alerts for database errors related to SQL syntax failures that may indicate injection attempts
• Implement real-time monitoring of database queries for unusual patterns such as information schema queries or bulk data extraction

How to Mitigate CVE-2025-2736

Immediate Actions Required

• Restrict access to the /admin/ directory to trusted IP addresses only using web server configuration or firewall rules
• Implement input validation on all user-supplied parameters, particularly date fields, using strict format checking
• Deploy a Web Application Firewall (WAF) to filter malicious SQL injection payloads
• Consider taking the affected application offline until a proper patch can be applied

Patch Information

As of the last update, no official patch has been released by PHPGurukul for this vulnerability. Organizations using the Old Age Home Management System 1.0 should monitor the PHP Gurukul website for security updates and patch releases. Additional technical details about this vulnerability can be found in the VulDB advisory and the GitHub CVE issue tracker.

Workarounds

• Implement prepared statements (parameterized queries) in the vulnerable PHP file by modifying the code to use PDO or MySQLi with parameter binding
• Add server-side input validation to ensure the fromdate parameter matches the expected date format (e.g., YYYY-MM-DD)
• Restrict administrative panel access through HTTP Basic Authentication or IP whitelisting as an additional security layer

# Apache .htaccess configuration to restrict admin access
# Place this file in the /admin/ directory

<Directory "/var/www/html/admin">
    # Restrict access to specific IP addresses
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
    
    # Deny all other requests
    Require all denied
</Directory>
