CVE-2025-11503: PHPGurukul Beauty Parlour SQLI Vuln

CVE-2025-11503 Overview

CVE-2025-11503 is a SQL Injection vulnerability affecting PHPGurukul Beauty Parlour Management System version 1.1. The vulnerability exists in the /admin/manage-services.php file, where improper handling of the delid parameter allows attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit improper input validation in the delid parameter to execute arbitrary SQL commands against the backend database, compromising data confidentiality, integrity, and availability.

Affected Products

• PHPGurukul Beauty Parlour Management System 1.1
• Web applications using the vulnerable /admin/manage-services.php endpoint

Technical Details for CVE-2025-11503

Vulnerability Analysis

This SQL Injection vulnerability stems from insufficient input validation in the administrative services management functionality. The /admin/manage-services.php file processes the delid parameter without proper sanitization or parameterized queries, allowing attackers to inject arbitrary SQL syntax. When an attacker crafts a malicious request with specially formatted SQL commands in the delid parameter, the application directly incorporates this input into database queries, enabling unauthorized 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), indicating that user-supplied input is improperly neutralized before being used in SQL query construction.

Root Cause

The root cause is the direct concatenation of user-supplied input (the delid parameter) into SQL queries without proper sanitization, escaping, or the use of parameterized prepared statements. This is a classic PHP web application vulnerability where developers fail to implement secure database interaction patterns.

Attack Vector

The attack can be performed remotely over the network without authentication requirements. An attacker sends a crafted HTTP request to the /admin/manage-services.php endpoint with a manipulated delid parameter containing SQL injection payloads. The malicious SQL syntax is then executed by the database server, potentially allowing attackers to:

• Extract sensitive data from the database
• Modify or delete existing records
• Bypass authentication mechanisms
• Potentially execute system commands depending on database configuration

The exploit has been publicly disclosed as noted in the GitHub CVE Issue Discussion, increasing the risk of exploitation in the wild.

Detection Methods for CVE-2025-11503

Indicators of Compromise

• Unusual SQL error messages in application logs or HTTP responses from /admin/manage-services.php
• Abnormal database query patterns or excessive database errors
• HTTP requests to /admin/manage-services.php containing special SQL characters in the delid parameter (e.g., single quotes, double dashes, UNION, SELECT keywords)
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to /admin/manage-services.php
• Monitor HTTP access logs for suspicious delid parameter values containing SQL keywords or special characters
• Deploy database activity monitoring to detect anomalous query patterns or unauthorized data access attempts
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging for all requests to administrative endpoints in the Beauty Parlour Management System
• Configure database audit logging to track all queries executed against sensitive tables
• Set up alerts for failed SQL queries or database errors that may indicate injection attempts
• Regularly review access logs for the /admin/manage-services.php endpoint for unusual activity patterns

How to Mitigate CVE-2025-11503

Immediate Actions Required

• Restrict access to the /admin/manage-services.php endpoint to trusted IP addresses only
• Implement a Web Application Firewall with SQL injection protection rules
• Audit and review all user input handling in the affected application
• Consider taking the affected functionality offline until a patch is available

Patch Information

No official vendor patch has been identified at the time of this publication. Organizations should monitor the PHP Gurukul Security Resources for security updates. Additional technical details and vulnerability tracking information is available through VulDB #327629.

Workarounds

• Implement input validation to whitelist only numeric values for the delid parameter
• Use parameterized queries or prepared statements for all database interactions involving user input
• Deploy a reverse proxy or WAF to filter malicious requests before they reach the application
• Apply the principle of least privilege to database user accounts used by the application
