CVE-2025-4917: PHPGurukul Auto/Taxi Stand SQLI Flaw

CVE-2025-4917 Overview

CVE-2025-4917 is a SQL injection vulnerability in PHPGurukul Auto/Taxi Stand Management System 1.0. The flaw resides in /admin/new-autoortaxi-entry-form.php, where the drivername parameter is concatenated directly into a backend SQL query without sanitization. Remote attackers can manipulate the parameter to inject arbitrary SQL statements against the application database. The issue is classified under [CWE-89] SQL Injection and [CWE-74] Improper Neutralization of Special Elements. The exploit details have been publicly disclosed through VulDB and a GitHub issue, increasing the likelihood of opportunistic exploitation. Additional parameters in the same endpoint may also be affected.

Critical Impact
Unauthenticated remote attackers can inject SQL through the drivername parameter to read, modify, or destroy administrative database content in the Auto/Taxi Stand Management System.

Affected Products

PHPGurukul Auto/Taxi Stand Management System 1.0
Administrative endpoint /admin/new-autoortaxi-entry-form.php
Deployments exposing the admin interface to untrusted networks

Technical Details for CVE-2025-4917

Vulnerability Analysis

The vulnerability allows attackers to inject SQL syntax through the drivername POST parameter submitted to /admin/new-autoortaxi-entry-form.php. The application builds its INSERT or SELECT statement by concatenating user input directly into the query string. An attacker supplying SQL metacharacters such as single quotes, comments, or UNION clauses breaks out of the intended literal and executes attacker-controlled SQL.

Successful exploitation can expose driver, vehicle, and administrator records stored in the application database. Attackers may also modify records, drop tables, or extract password hashes used for administrator authentication. The advisory notes that other parameters on the same form may share the same defect.

The attack requires no authentication and no user interaction. It is reachable over the network whenever the admin module is exposed. Public disclosure on VulDB and the associated GitHub Issue Discussion provides enough detail to reproduce the attack with standard tooling.

Root Cause

The root cause is missing input validation and the absence of parameterized queries in the entry-form handler. PHP code accepts the drivername value and embeds it into a SQL statement without prepared statements, escaping, or type enforcement, violating secure coding guidance for [CWE-89].

Attack Vector

The attack vector is network-based against the HTTP admin endpoint. An attacker submits a crafted POST request to /admin/new-autoortaxi-entry-form.php with a malicious drivername value. Automated tools such as sqlmap can enumerate databases, dump tables, and confirm injection points without prior credentials.

The vulnerability manifests when user-supplied form data is concatenated into a SQL statement in the entry-form script. No verified proof-of-concept code is published by the vendor. Refer to the VulDB #309474 entry for technical specifics.

Detection Methods for CVE-2025-4917

Indicators of Compromise

HTTP POST requests to /admin/new-autoortaxi-entry-form.php containing SQL metacharacters such as ', --, UNION SELECT, SLEEP(, or OR 1=1 in the drivername field
Web server access logs showing repeated form submissions from a single source with unusual response sizes or 500 errors
Database error messages returned to clients referencing MySQL syntax errors tied to driver entry operations
Unexpected new administrator accounts or modified driver records in the application database

Detection Strategies

Inspect web application firewall and reverse proxy logs for SQL injection signatures targeting the drivername parameter and adjacent form fields
Enable MySQL general or slow query logging and review queries originating from the entry-form endpoint for malformed syntax or stacked statements
Correlate authentication anomalies in the admin module with preceding requests to /admin/new-autoortaxi-entry-form.php

Monitoring Recommendations

Alert on outbound database queries that contain UNION, INFORMATION_SCHEMA, or time-based functions originating from the taxi stand application service account
Monitor for spikes in 4xx/5xx responses on admin form endpoints, which often accompany blind SQL injection probing
Capture full HTTP request bodies for admin endpoints to support post-incident forensics

How to Mitigate CVE-2025-4917

Immediate Actions Required

Restrict network access to /admin/ paths using IP allowlists, VPN, or HTTP basic authentication at the web server layer until the application is patched
Deploy WAF rules that block SQL injection patterns on the drivername parameter and other admin form fields
Rotate administrator credentials and audit the database for unauthorized rows or schema changes
Run the affected service under a database account with least-privilege permissions to limit injection impact

Patch Information

No vendor patch is referenced in the NVD entry or vendor advisory listings at publication time. Operators should monitor PHP Gurukul Resources for updates. Until a fix is released, source code remediation should replace string concatenation in new-autoortaxi-entry-form.php with prepared statements using PDO or mysqli with bound parameters.

Workarounds

Apply server-side input validation that restricts drivername to an allowlist of alphabetic characters and spaces
Place the admin module behind authentication enforced at the web server before requests reach PHP
Disable or remove the vulnerable endpoint if the entry form is not in active use

bash

# Example Apache configuration restricting admin access by source IP
<Location "/admin/">
    Require ip 10.0.0.0/24
    Require ip 192.168.1.0/24
</Location>

# Example ModSecurity rule blocking SQLi patterns on drivername
SecRule ARGS:drivername "@rx (?:'|--|\bunion\b|\bselect\b|\bsleep\s*\()" \
