CVE-2025-4914: PHPGurukul Auto/Taxi Stand SQLi Flaw

CVE-2025-4914 Overview

A SQL injection vulnerability has been identified in PHPGurukul Auto Taxi Stand Management System version 1.0. The vulnerability exists in the /admin/forgot-password.php file, where the email parameter is not properly sanitized before being used in SQL queries. This allows remote attackers to execute arbitrary SQL commands against the underlying database without authentication.

Critical Impact

Remote unauthenticated attackers can exploit this SQL injection vulnerability to access, modify, or delete sensitive data in the application database, potentially compromising user credentials and administrative accounts.

Technical Details for CVE-2025-4914

Vulnerability Analysis

This SQL injection vulnerability affects the password recovery functionality in the administrative interface of PHPGurukul Auto Taxi Stand Management System. The flaw resides in the forgot-password.php file located in the /admin/ directory. When a user submits an email address through the password reset form, the application fails to properly validate and sanitize this input before incorporating it into SQL queries.

The vulnerability is exploitable remotely without any authentication requirements. An attacker can craft malicious SQL statements through the email parameter to manipulate database queries. This could lead to unauthorized data access, data modification, or complete database compromise. The public disclosure of this exploit increases the risk of active exploitation in the wild.

Root Cause

The root cause of this vulnerability is insufficient input validation and the absence of parameterized queries or prepared statements in the forgot-password.php file. The application directly concatenates user-supplied input from the email parameter into SQL queries, allowing attackers to inject malicious SQL code that alters the intended query logic.

Attack Vector

The attack can be initiated remotely over the network without requiring any prior authentication or user interaction. An attacker targets the /admin/forgot-password.php endpoint and submits specially crafted input through the email parameter. The malicious payload is then executed by the database server, potentially allowing the attacker to bypass authentication, extract sensitive data, modify records, or execute administrative operations on the database.

The vulnerability follows CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) classifications. Detailed technical information about the exploitation methodology can be found in the GitHub Issue Report.

Detection Methods for CVE-2025-4914

Indicators of Compromise

• Unusual or malformed requests to /admin/forgot-password.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords in the email parameter
• Database error messages appearing in application logs or responses indicating SQL syntax errors
• Unexpected database queries or access patterns originating from the web application
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests targeting the /admin/forgot-password.php endpoint
• Monitor application logs for repeated failed password reset attempts with suspicious payloads
• Enable database query logging and analyze for anomalous query patterns or SQL injection signatures
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Set up alerts for any requests to /admin/forgot-password.php containing SQL metacharacters or keywords
• Monitor database performance metrics for unusual query execution times or resource consumption that may indicate exploitation attempts
• Regularly audit database access logs for unauthorized read or write operations
• Implement real-time log analysis to correlate suspicious web requests with database activity

How to Mitigate CVE-2025-4914

Immediate Actions Required

• Remove or disable public access to the /admin/forgot-password.php endpoint until a patch is applied
• Implement network-level access controls to restrict access to the administrative interface to trusted IP addresses only
• Deploy a web application firewall with SQL injection protection rules in front of the application
• Review database user permissions and apply the principle of least privilege to limit potential damage from successful exploitation

Patch Information

As of the last update, no official patch has been released by PHPGurukul for this vulnerability. Organizations using this software should monitor the PHPGurukul website for security updates and apply patches immediately when available. Additional vulnerability details can be found at VulDB #309471.

Workarounds

• Implement input validation to sanitize the email parameter by allowing only valid email address characters and format
• Modify the vulnerable code to use prepared statements or parameterized queries instead of string concatenation for SQL operations
• Add a CAPTCHA mechanism to the password reset form to prevent automated exploitation attempts
• Consider replacing or discontinuing use of this application until the vendor provides an official security fix

# Example: Block suspicious requests to the vulnerable endpoint using iptables (temporary measure)
# This blocks access to the admin directory from external networks
iptables -A INPUT -p tcp --dport 80 -m string --string "/admin/forgot-password.php" --algo bm -j DROP

# Apache .htaccess example to restrict admin access by IP
# Add to /admin/.htaccess
# <Files "forgot-password.php">
#   Require ip 192.168.1.0/24
# </Files>
