CVE-2025-2380: Phpgurukul AVMS SQLi Vulnerability

CVE-2025-2380 Overview

A SQL injection vulnerability has been identified in PHPGurukul Apartment Visitors Management System version 1.0. This vulnerability exists in the /admin-profile.php file, where improper handling of the mobilenumber parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially compromising the confidentiality, integrity, and availability of the application's database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database records, or potentially gain unauthorized access to the underlying system through the vulnerable mobilenumber parameter in /admin-profile.php.

Technical Details for CVE-2025-2380

Vulnerability Analysis

This SQL injection vulnerability affects the admin profile functionality of PHPGurukul Apartment Visitors Management System. The application fails to properly sanitize user-supplied input in the mobilenumber parameter before incorporating it into SQL queries. This lack of input validation allows attackers to craft malicious input that manipulates the underlying SQL query structure, enabling unauthorized database operations.

The vulnerability is classified under 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). These weaknesses indicate that the application does not adequately neutralize special characters that could be interpreted as SQL syntax.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries in the /admin-profile.php file. The mobilenumber parameter is directly concatenated into SQL queries without sanitization, escaping, or the use of prepared statements. This design flaw allows user-controlled input to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack can be initiated remotely over the network without requiring authentication. An attacker can submit specially crafted input to the mobilenumber parameter through HTTP requests to the /admin-profile.php endpoint. The malicious payload would typically include SQL metacharacters and commands designed to alter the query logic, extract data from the database, or perform other unauthorized database operations.

The vulnerability has been publicly disclosed, and technical details are available through the GitHub CVE Issue Discussion. Additional vulnerability tracking information can be found at VulDB #299879.

Detection Methods for CVE-2025-2380

Indicators of Compromise

• Unusual or malformed values in the mobilenumber parameter in web server access logs
• Database error messages exposed in application responses indicating SQL syntax errors
• Unexpected database queries or data exfiltration patterns in database audit logs
• Access attempts to /admin-profile.php with encoded SQL injection payloads

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the mobilenumber parameter
• Monitor application logs for requests containing SQL metacharacters such as single quotes, double dashes, or UNION keywords
• Deploy intrusion detection signatures that identify common SQL injection attack patterns targeting PHP applications
• Review database query logs for anomalous query structures or unauthorized data access attempts

Monitoring Recommendations

• Enable detailed logging for the /admin-profile.php endpoint and monitor for suspicious request patterns
• Configure database auditing to track queries executed against user-related tables
• Set up alerts for failed login attempts or unusual administrative activity following suspicious requests
• Implement real-time log analysis to correlate web requests with database activity

How to Mitigate CVE-2025-2380

Immediate Actions Required

• Restrict access to the /admin-profile.php endpoint to trusted IP addresses only until a patch is applied
• Implement input validation to reject non-numeric characters in the mobilenumber parameter
• Deploy a Web Application Firewall with SQL injection protection rules
• Review application logs for evidence of exploitation attempts

Patch Information

As of the last update on 2025-05-06, no official patch has been released by PHPGurukul for this vulnerability. Organizations using the Apartment Visitors Management System 1.0 should monitor the PHPGurukul website for security updates and consider implementing the workarounds described below until an official fix is available.

Workarounds

• Modify the vulnerable code to use prepared statements with parameterized queries instead of string concatenation
• Implement server-side input validation to ensure the mobilenumber parameter contains only numeric digits
• Add a Web Application Firewall in front of the application to filter malicious SQL injection attempts
• Consider taking the application offline or restricting access if it processes sensitive visitor data

# Example: Restrict access to admin-profile.php via Apache .htaccess
<Files "admin-profile.php">
    Order deny,allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
