CVE-2025-3299 Overview
A critical SQL injection vulnerability has been identified in PHPGurukul Men Salon Management System version 1.0. The vulnerability exists in the /appointment.php file, where improper handling of the Name parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially compromising the entire database and sensitive customer information stored within the application.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to read, modify, or delete database contents, potentially accessing sensitive customer data, appointment records, and administrative credentials.

Technical Details for CVE-2025-3299
Vulnerability Analysis
This SQL injection vulnerability stems from insufficient input validation in the appointment booking functionality of the Men Salon Management System. The application fails to properly sanitize user-supplied input in the Name parameter before incorporating it into SQL queries. This weakness allows attackers to break out of the intended query structure and execute arbitrary SQL commands against the underlying database.
The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where untrusted data is sent to an interpreter as part of a command or query.
Root Cause
The root cause of this vulnerability is the direct concatenation of user input into SQL queries without proper parameterization or input sanitization. The Name field in the appointment form accepts arbitrary input that is passed directly to the database query, allowing attackers to inject SQL metacharacters and modify the query logic.
Attack Vector
The attack can be launched remotely over the network without any authentication requirements. An attacker can submit a specially crafted payload through the Name field in the appointment form on /appointment.php. By injecting SQL syntax such as single quotes, comment characters, or UNION-based queries, the attacker can manipulate the database operations.
The vulnerability has been publicly disclosed, and exploit details are available through the GitHub CVE Issue Tracking repository. Attackers could potentially:
- Extract sensitive data from the database including customer information
- Modify or delete appointment records
- Bypass authentication mechanisms
- Escalate privileges to administrative access
- Potentially achieve remote code execution depending on database configuration
Detection Methods for CVE-2025-3299
Indicators of Compromise
- Unusual or malformed entries in the Name field of appointment records containing SQL metacharacters (single quotes, double dashes, semicolons)
- Database error messages appearing in web server logs or application responses
- Unexpected database queries or commands in database audit logs
- Signs of data exfiltration or unauthorized database access patterns
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests targeting /appointment.php
- Enable database query logging and monitor for anomalous queries containing injection patterns
- Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
- Review web server access logs for requests to /appointment.php with suspicious parameter values
Monitoring Recommendations
- Configure real-time alerting for database errors or failed query attempts
- Monitor for bulk data access patterns that may indicate data exfiltration
- Implement application-level logging for all user input to appointment forms
- Set up anomaly detection for unusual database query patterns or response sizes
How to Mitigate CVE-2025-3299
Immediate Actions Required
- Take the affected Men Salon Management System offline or restrict access to the /appointment.php endpoint
- Implement input validation and sanitization for all user-supplied parameters
- Review database logs for evidence of exploitation attempts
- Audit the database for unauthorized changes or data theft
Patch Information
As of the last update on April 8, 2025, no official patch has been released by PHPGurukul for this vulnerability. Organizations using this software should monitor the PHP Gurukul Security Blog for security updates. Additional vulnerability details are available through VulDB #303494.
Workarounds
- Implement prepared statements with parameterized queries in the /appointment.php file to prevent SQL injection
- Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the application
- Apply strict input validation using allowlist patterns for the Name parameter (alphanumeric characters and limited special characters only)
- Restrict database user privileges to minimum required operations (principle of least privilege)
- Consider isolating the application in a network segment with limited access
