CVE-2025-3370: Men Salon Management System SQLi Flaw

CVE-2025-3370 Overview

A critical SQL Injection vulnerability has been discovered in PHPGurukul Men Salon Management System version 1.0. The vulnerability exists within the /admin/admin-profile.php file, where the contactnumber parameter is not properly sanitized before being used in database queries. This flaw allows remote attackers to inject malicious SQL statements, potentially leading to unauthorized data access, modification, or deletion. The exploit has been publicly disclosed, and other parameters within the application may also be affected by similar injection vulnerabilities.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to bypass authentication, extract sensitive database contents, modify or delete data, and potentially gain further access to the underlying server infrastructure.

Technical Details for CVE-2025-3370

Vulnerability Analysis

This SQL Injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) exists in the admin profile functionality of PHPGurukul Men Salon Management System. The application fails to properly validate and sanitize user-supplied input through the contactnumber parameter before incorporating it into SQL queries. This allows attackers to manipulate the query structure by injecting malicious SQL syntax.

The vulnerability is remotely exploitable without authentication requirements, making it accessible to any attacker with network access to the target application. The lack of input validation in this PHP-based web application creates a direct pathway for database manipulation. While the immediate impact includes unauthorized read and write access to the database, successful exploitation could potentially lead to complete system compromise depending on database privileges and server configuration.

Root Cause

The root cause of this vulnerability lies in the improper handling of user input in the /admin/admin-profile.php file. The contactnumber parameter is directly incorporated into SQL queries without adequate sanitization, parameterization, or prepared statements. This classic input validation failure allows attackers to break out of the intended query context and execute arbitrary SQL commands. The vulnerability disclosure also indicates that other parameters within the application may suffer from the same coding deficiency.

Attack Vector

The attack is network-based, requiring no user interaction for exploitation. An attacker can craft malicious HTTP requests to the /admin/admin-profile.php endpoint with specially crafted values in the contactnumber parameter. The injected SQL code is then executed by the database engine with the same privileges as the application's database connection.

The exploitation technique involves inserting SQL metacharacters and commands within the contactnumber field. For instance, an attacker could use techniques such as UNION-based injection to extract data from other tables, blind SQL injection to enumerate database contents through conditional responses, or stacked queries to modify or delete database records. The publicly disclosed nature of this exploit increases the risk of widespread exploitation against unpatched systems.

Detection Methods for CVE-2025-3370

Indicators of Compromise

• Unusual HTTP requests to /admin/admin-profile.php containing SQL syntax such as single quotes, UNION statements, or commenting characters in the contactnumber parameter
• Database error messages appearing in application logs or HTTP responses indicating SQL syntax errors
• Unexpected database queries accessing tables or data outside normal application behavior
• Evidence of data exfiltration or unauthorized modifications in database audit logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the contactnumber parameter
• Implement application-level logging to capture all requests to /admin/admin-profile.php and analyze for suspicious patterns
• Configure database activity monitoring to alert on unusual query patterns or access to sensitive tables
• Use intrusion detection systems (IDS) with signatures for SQL injection attack vectors

Monitoring Recommendations

• Monitor web server access logs for requests containing SQL injection payloads directed at the vulnerable endpoint
• Set up database query logging and analyze for anomalous SELECT, UNION, or modification statements
• Implement real-time alerting for multiple failed login attempts or authentication bypass indicators
• Review application error logs for SQL-related exceptions that may indicate exploitation attempts

How to Mitigate CVE-2025-3370

Immediate Actions Required

• Remove or restrict public access to the PHPGurukul Men Salon Management System until a patch is available or mitigations are in place
• Implement Web Application Firewall rules to block SQL injection attempts targeting the /admin/admin-profile.php endpoint
• Review database permissions to ensure the application uses least-privilege access principles
• Conduct a thorough security audit of other parameters and endpoints within the application for similar vulnerabilities

Patch Information

No official vendor patch has been released at the time of this publication. Organizations using PHPGurukul Men Salon Management System should monitor the PHPGurukul website for security updates. Additional details about this vulnerability can be found in the VulDB entry #303615 and the GitHub CVE Issue.

Workarounds

• Implement input validation by sanitizing the contactnumber parameter to accept only numeric characters before processing
• Convert vulnerable SQL queries to use prepared statements with parameterized queries to prevent injection
• Deploy a reverse proxy or WAF in front of the application to filter malicious requests
• Restrict access to the admin interface via IP allowlisting or VPN requirements
