CVE-2025-4916: PHPGurukul Auto/Taxi Stand SQLI Flaw

CVE-2025-4916 Overview

A critical SQL injection vulnerability has been identified in PHPGurukul Auto Taxi Stand Management System version 1.0. The vulnerability exists in the admin profile functionality, specifically within the /admin/admin-profile.php file. Attackers can exploit improper input validation of the mobilenumber parameter to inject malicious SQL queries, potentially compromising the underlying database and sensitive information stored within the application.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability without authentication to extract, modify, or delete database contents, potentially gaining unauthorized access to sensitive taxi stand management data and administrative credentials.

Affected Products

• PHPGurukul Auto/Taxi Stand Management System 1.0
• Web applications using the vulnerable /admin/admin-profile.php endpoint
• Systems running unpatched versions of the management platform

Technical Details for CVE-2025-4916

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the admin profile management functionality. The mobilenumber parameter in /admin/admin-profile.php does not properly sanitize user-supplied input before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are executed by the database server with the same privileges as the application's database user.

The vulnerability is remotely exploitable over the network without requiring any special privileges or user interaction, making it particularly dangerous for internet-facing deployments. The public disclosure of this exploit further increases the risk, as attack details are readily available to malicious actors. Additional parameters within the same endpoint may also be vulnerable to similar injection attacks.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) when handling the mobilenumber parameter. The application directly concatenates user-supplied input into SQL query strings without sanitization or escaping, enabling classic SQL injection attacks. This represents a violation of secure coding practices outlined in 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).

Attack Vector

The attack can be initiated remotely over the network by submitting a crafted HTTP request to the /admin/admin-profile.php endpoint. An attacker would manipulate the mobilenumber parameter to include SQL meta-characters and malicious query fragments. Successful exploitation could allow the attacker to:

• Extract sensitive data from the database including user credentials and personal information
• Modify or delete database records affecting taxi stand operations
• Bypass authentication mechanisms to gain administrative access
• Potentially escalate to remote code execution if database features like xp_cmdshell (MSSQL) or INTO OUTFILE (MySQL) are available

The vulnerability can be exploited by injecting SQL syntax into the mobilenumber parameter. For example, an attacker might append SQL commands such as ' OR '1'='1 or use UNION-based injection techniques to extract data from other database tables. Technical details and proof-of-concept information can be found in the GitHub Issue Discussion and VulDB #309473.

Detection Methods for CVE-2025-4916

Indicators of Compromise

• Unusual HTTP requests to /admin/admin-profile.php containing SQL keywords such as UNION, SELECT, INSERT, DELETE, or OR
• Web server logs showing repeated requests with special characters in the mobilenumber parameter including single quotes, double dashes, or semicolons
• Database error messages appearing in application responses indicating query syntax errors
• Unexpected database queries or data modifications in database audit logs

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns targeting the mobilenumber parameter
• Configure intrusion detection systems (IDS) to alert on suspicious HTTP traffic containing SQL meta-characters
• Enable detailed logging on the web server and database to capture malicious query attempts
• Deploy application-level monitoring to detect anomalous parameter values in admin profile requests

Monitoring Recommendations

• Monitor web application logs for requests to /admin/admin-profile.php with anomalous parameter lengths or special characters
• Set up alerting for database errors that may indicate failed SQL injection attempts
• Review database query logs for unexpected data extraction patterns or unauthorized privilege escalation attempts
• Implement real-time monitoring of admin account activities for suspicious modifications

How to Mitigate CVE-2025-4916

Immediate Actions Required

• Restrict network access to the /admin/admin-profile.php endpoint to trusted IP addresses only
• Implement a Web Application Firewall (WAF) with SQL injection protection rules as an immediate compensating control
• Review and audit database accounts used by the application, ensuring they have minimal required privileges
• Consider temporarily disabling the affected admin profile functionality until a patch is available

Patch Information

No official vendor patch has been released at the time of publication. Organizations should monitor the PHPGurukul website for security updates. Given the public disclosure of this vulnerability, applying defensive measures immediately is strongly recommended. Users are advised to check VulDB Submission #579098 for updates on remediation status.

Workarounds

• Modify the affected PHP code to use prepared statements with parameterized queries instead of string concatenation for database operations
• Implement input validation to restrict the mobilenumber parameter to numeric characters only using server-side validation
• Deploy a reverse proxy or WAF in front of the application configured to filter SQL injection attack patterns
• Disable or restrict access to the admin profile page until the vulnerability can be properly remediated

# Example: Apache .htaccess to restrict admin access by IP
<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>
