CVE-2025-4554: Apartment Visitors Management System SQLi

CVE-2025-4554 Overview

A critical SQL injection vulnerability has been discovered in PHPGurukul Apartment Visitors Management System version 1.0. The vulnerability exists in the /admin/bwdates-passreports-details.php file, where improper handling of the fromdate and todate parameters allows attackers to inject malicious SQL statements. This flaw can be exploited remotely without authentication, potentially compromising the entire database backend.

Critical Impact

Unauthenticated attackers can exploit this SQL injection vulnerability remotely to access, modify, or delete sensitive visitor management data, potentially compromising resident information and facility security records.

Affected Products

• PHPGurukul Apartment Visitors Management System 1.0
• Installations using the vulnerable /admin/bwdates-passreports-details.php endpoint
• Systems without proper input validation on date parameters

Technical Details for CVE-2025-4554

Vulnerability Analysis

This SQL injection vulnerability stems from inadequate input sanitization in the date report functionality of the administrative panel. The affected endpoint /admin/bwdates-passreports-details.php processes date range parameters (fromdate and todate) without proper validation or parameterized query usage. When these values are passed directly into SQL queries, attackers can craft malicious input to manipulate the underlying database operations.

The vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The network-accessible attack vector combined with no authentication requirements makes this vulnerability particularly dangerous for exposed installations.

Root Cause

The root cause is the direct concatenation of user-supplied fromdate and todate parameter values into SQL queries without proper sanitization, escaping, or the use of prepared statements. PHP applications that build SQL queries by string concatenation are inherently vulnerable when untrusted input is incorporated without validation.

Attack Vector

The attack can be initiated remotely over the network without requiring any authentication or user interaction. An attacker can access the /admin/bwdates-passreports-details.php endpoint and submit crafted date parameter values containing SQL syntax. The injection payload embedded within the fromdate or todate parameters is then processed by the database engine, allowing the attacker to execute arbitrary SQL commands.

The manipulation of these date fields could enable attackers to perform various malicious actions including extracting sensitive visitor records, dumping database credentials, modifying visitor logs, or potentially achieving command execution depending on the database configuration and privileges.

Detection Methods for CVE-2025-4554

Indicators of Compromise

• Unusual SQL syntax or special characters (', ", --, ;, UNION, SELECT) in web server access logs targeting /admin/bwdates-passreports-details.php
• Database error messages appearing in application logs indicating malformed queries
• Unexpected database queries or data exfiltration attempts logged in database audit trails
• Access attempts to the administrative date reports endpoint from suspicious or foreign IP addresses

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in request parameters
• Enable detailed logging for the /admin/ directory and monitor for anomalous request patterns
• Configure database audit logging to capture unusual SELECT, UNION, or information schema queries
• Deploy intrusion detection system (IDS) signatures specific to SQL injection attack patterns

Monitoring Recommendations

• Monitor web server logs for requests containing SQL keywords or special characters in the fromdate and todate parameters
• Set up alerting for multiple failed requests or error responses from the vulnerable endpoint
• Track database query performance for anomalies that may indicate injection-based data extraction
• Review authentication logs for unauthorized access attempts to administrative functions

How to Mitigate CVE-2025-4554

Immediate Actions Required

• Restrict access to /admin/bwdates-passreports-details.php via IP whitelisting or additional authentication layers
• Implement a Web Application Firewall (WAF) to filter SQL injection attempts before they reach the application
• Consider taking the date reports functionality offline until a patch is applied
• Review database user permissions and limit privileges to minimum required for application operation

Patch Information

At the time of this analysis, no official vendor patch has been released for this vulnerability. Organizations should monitor the PHPGurukul website and the GitHub issue discussion for updates. Additional technical details are available through VulDB #308301.

Workarounds

• Implement server-side input validation to ensure fromdate and todate parameters contain only valid date formats
• Modify the vulnerable PHP code to use prepared statements with parameterized queries instead of string concatenation
• Deploy a reverse proxy or WAF with SQL injection detection capabilities to filter malicious requests
• Restrict network access to the administrative panel to trusted IP addresses only

# Example: Restrict access to admin directory via .htaccess
# Add to /admin/.htaccess
<FilesMatch "bwdates-passreports-details.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</FilesMatch>
