CVE-2025-3829: Men Salon Management System SQLi Flaw

CVE-2025-3829 Overview

A SQL injection vulnerability has been identified in PHPGurukul Men Salon Management System version 1.0. This critical flaw exists in the /admin/sales-reports-detail.php file, where improper handling of the fromdate and todate parameters allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to the underlying database, data exfiltration, and manipulation of sensitive business information.

Critical Impact

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

Technical Details for CVE-2025-3829

Vulnerability Analysis

This SQL injection vulnerability resides in the administrative sales reporting functionality of the Men Salon Management System. The affected endpoint /admin/sales-reports-detail.php processes date range parameters (fromdate and todate) that are used to filter sales data. These parameters are incorporated into SQL queries without proper sanitization or parameterized query implementation, creating an injection point that attackers can leverage to execute arbitrary SQL commands against the backend database.

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 exploit has been publicly disclosed, increasing the risk of active exploitation in the wild.

Root Cause

The root cause of this vulnerability is the direct concatenation of user-supplied input into SQL query strings without implementing proper input validation, sanitization, or parameterized queries. The fromdate and todate parameters are passed directly from HTTP request parameters into database queries, allowing attackers to break out of the intended query structure and inject malicious SQL statements.

Attack Vector

The attack can be executed remotely over the network by an unauthenticated attacker targeting the administrative sales reports endpoint. An attacker can craft malicious HTTP requests containing SQL injection payloads in the fromdate or todate parameters. When the application processes these requests, the injected SQL code is executed against the database, potentially enabling the attacker to:

• Extract sensitive customer information, appointment records, and financial data
• Modify or delete database records
• Bypass authentication mechanisms
• Escalate privileges within the application
• In some configurations, execute system commands on the database server

The vulnerability is accessible through standard web requests, making exploitation straightforward for attackers with basic SQL injection knowledge. Technical details and proof-of-concept information have been documented in the GitHub CVE Issue Discussion and tracked via VulDB #305736.

Detection Methods for CVE-2025-3829

Indicators of Compromise

• Unusual or malformed requests to /admin/sales-reports-detail.php containing SQL syntax characters (single quotes, double dashes, UNION, SELECT, etc.)
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database queries or access patterns in database audit logs
• Anomalous data access or extraction from sales-related database tables

Detection Strategies

• Implement web application firewall (WAF) rules to detect SQL injection patterns in the fromdate and todate parameters
• Monitor web server access logs for suspicious requests to the affected endpoint with encoded or plaintext SQL injection payloads
• Deploy intrusion detection signatures for common SQL injection attack patterns targeting date parameters
• Enable database query logging and alert on queries containing unexpected SQL commands or syntax

Monitoring Recommendations

• Enable detailed logging for the /admin/sales-reports-detail.php endpoint and review for anomalous parameter values
• Configure database activity monitoring to detect unauthorized data access or suspicious query patterns
• Set up alerts for multiple failed or error-generating requests to administrative endpoints
• Implement real-time monitoring for database connections and query execution from the web application

How to Mitigate CVE-2025-3829

Immediate Actions Required

• Restrict access to the /admin/sales-reports-detail.php endpoint to trusted IP addresses only
• Implement input validation on the fromdate and todate parameters to accept only properly formatted date values
• Deploy a web application firewall with SQL injection protection rules in front of the application
• Consider taking the affected functionality offline until a proper fix can be implemented

Patch Information

As of the last modification date (2025-04-28), no official patch has been released by PHPGurukul for this vulnerability. Users should monitor the PHP Gurukul Security Resources for updates and security advisories. In the absence of an official patch, organizations should implement the workarounds and mitigations described below.

Workarounds

• Implement prepared statements with parameterized queries in the affected PHP file to properly handle user input
• Add server-side input validation to enforce strict date format patterns (e.g., YYYY-MM-DD) and reject any input containing SQL metacharacters
• Restrict database user permissions for the application to limit the impact of successful SQL injection
• Enable PHP's mysqli_real_escape_string() or equivalent escaping functions as a temporary measure until proper parameterization is implemented

# Example .htaccess rules to restrict access and filter malicious input
# Add to web server configuration for the admin directory

# Restrict admin access to specific IP addresses
<Files "sales-reports-detail.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
