CVE-2025-7490: PHPGurukul Vehicle Parking System SQLi

CVE-2025-7490 Overview

CVE-2025-7490 is a SQL injection vulnerability in PHPGurukul Vehicle Parking Management System version 1.13. The flaw resides in the /admin/reg-users.php script, where the del parameter is passed to a database query without proper sanitization. Authenticated attackers can manipulate this parameter remotely to inject arbitrary SQL statements. The exploit details have been publicly disclosed, increasing the risk of opportunistic abuse against exposed installations. The vulnerability is tracked under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component.

Critical Impact
Remote attackers with low-privileged access can inject SQL through the del parameter of reg-users.php to read, modify, or delete records in the application database.

Affected Products

PHPGurukul Vehicle Parking Management System 1.13
Deployments exposing /admin/reg-users.php to the network
Installations using the unpatched admin user management module

Technical Details for CVE-2025-7490

Vulnerability Analysis

The vulnerability exists in the administrative user management component of PHPGurukul Vehicle Parking Management System 1.13. The /admin/reg-users.php script accepts a del parameter through an HTTP request to identify the record targeted for deletion. The application concatenates this user-supplied input directly into a SQL statement without parameterization or input validation. An authenticated attacker with access to the admin interface can supply crafted SQL syntax through the del parameter to alter the structure of the executed query. Successful exploitation allows reading sensitive tables, modifying user records, or destroying data. The issue is reachable remotely over the network and requires no user interaction once the attacker has valid low-privilege credentials.

Root Cause

The root cause is the absence of prepared statements and input sanitization in the deletion handler within reg-users.php. The del parameter flows from the HTTP request into a dynamic SQL query, allowing operators and clauses such as UNION SELECT or OR 1=1 to be appended. This pattern matches the broader CWE-74 injection class.

Attack Vector

Exploitation requires network access to the admin panel and valid credentials. The attacker issues a GET or POST request to /admin/reg-users.php with a malicious del value, for example appending boolean-based or UNION-based payloads. Because the public proof-of-concept has been disclosed via the GitHub issue tracker and indexed by VulDB entry #316140, automated scanners can readily incorporate the technique.

No verified exploit code is reproduced here. Refer to the published advisory for technical proof-of-concept details.

Detection Methods for CVE-2025-7490

Indicators of Compromise

HTTP requests to /admin/reg-users.php containing SQL metacharacters such as single quotes, UNION, SELECT, or -- in the del parameter
Web server logs showing anomalously long query strings targeting the del parameter
Database errors or unexpected INFORMATION_SCHEMA lookups originating from the parking management application user

Detection Strategies

Deploy web application firewall signatures that flag SQL injection patterns against the reg-users.php endpoint
Correlate authentication events with subsequent admin panel requests containing suspicious del parameter values
Enable verbose query logging on the backend database to identify malformed or unauthorized DELETE and UNION statements

Monitoring Recommendations

Alert on repeated 500 errors or SQL syntax exceptions emitted by the application stack
Monitor administrative account activity for off-hours access or access from unusual source IP ranges
Track outbound data volume from the database server to detect bulk extraction following injection

How to Mitigate CVE-2025-7490

Immediate Actions Required

Restrict network access to /admin/ paths using IP allowlists or VPN-only access until a patch is applied
Rotate all administrative credentials and audit recently created or modified user accounts
Place a web application firewall in front of the application with rules blocking SQL syntax in the del parameter

Patch Information

No vendor patch has been published in the available references at the time of writing. Monitor the PHPGurukul website for an official fix. Until a vendor update is available, administrators should apply input validation in reg-users.php by casting the del parameter to an integer and migrating the deletion query to a prepared statement.

Workarounds

Modify reg-users.php to validate that del is strictly numeric before use in any SQL query
Replace inline SQL concatenation with parameterized queries using PDO or MySQLi prepared statements
Apply the principle of least privilege to the database account used by the application, removing DROP and ALTER permissions

bash

# Example WAF rule (ModSecurity) to block SQLi patterns on the vulnerable endpoint
SecRule REQUEST_URI "@beginsWith /admin/reg-users.php" \
  "chain,deny,status:403,id:1007490,msg:'CVE-2025-7490 SQLi attempt on del parameter'"
  SecRule ARGS:del "!@rx ^[0-9]+$" "t:none"
