CVE-2025-7520: Vehicle Parking Management System SQLi Flaw

CVE-2025-7520 Overview

CVE-2025-7520 is a SQL injection vulnerability in PHPGurukul Vehicle Parking Management System version 1.13. The flaw resides in the /admin/manage-category.php script, where the del parameter is passed to a database query without proper sanitization. A remote authenticated attacker can manipulate the del argument to inject arbitrary SQL statements. The exploit details have been publicly disclosed, increasing the risk of opportunistic abuse. The vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Remote attackers with low-privilege access can inject SQL queries through the del parameter, exposing application data and administrative records.

Technical Details for CVE-2025-7520

Vulnerability Analysis

The vulnerability exists in the administrative category management script /admin/manage-category.php. The script accepts a del parameter from HTTP requests and concatenates the value into a SQL query without parameterized binding or input validation. As a result, an attacker can append SQL syntax to the del value and alter the structure of the executed query. Exploitation requires network access to the admin interface and low-privilege authentication on the application.

Root Cause

The root cause is improper neutralization of user-supplied input passed into a SQL query. The application directly interpolates the del request parameter into the SQL statement instead of using prepared statements or escaping routines. This pattern is consistent with [CWE-74] injection weaknesses commonly found in PHP applications that rely on string concatenation for query construction.

Attack Vector

The attack is initiated remotely over the network against the /admin/manage-category.php endpoint. An attacker supplies a crafted value for the del parameter, such as a numeric identifier followed by SQL meta-characters, to extract or manipulate database records. Public disclosure on VulDB (entry 316217) and the GitHub Issue on myCVE provides technical references describing the affected parameter.

No verified proof-of-concept code is referenced in the NVD entry. See the VulDB CVE Analysis #316217 for additional technical context describing the injection payload format.

Detection Methods for CVE-2025-7520

Indicators of Compromise

HTTP requests to /admin/manage-category.php containing SQL meta-characters such as ', --, UNION, or SLEEP( in the del query string.
Web server access logs showing repeated requests with varying del values from a single source IP.
Database error messages or anomalous response sizes returned from manage-category.php.

Detection Strategies

Deploy web application firewall (WAF) signatures that flag SQL injection patterns targeting the del parameter.
Inspect PHP and MySQL error logs for syntax errors originating from manage-category.php.
Correlate authentication events with subsequent abnormal query activity against the parking management database.

Monitoring Recommendations

Enable verbose query logging on the MySQL backend during incident response to capture injected statements.
Monitor outbound database traffic for unexpected SELECT volume or INFORMATION_SCHEMA access from the application server.
Alert on administrative account logins followed by URL-encoded SQL keywords in request parameters.

How to Mitigate CVE-2025-7520

Immediate Actions Required

Restrict access to /admin/manage-category.php to trusted IP ranges or place the admin panel behind a VPN.
Rotate administrative credentials and review category management audit trails for unauthorized deletions.
Deploy WAF rules to block SQL meta-characters in the del parameter until a vendor fix is verified.

Patch Information

No official vendor advisory or patched release has been published for PHPGurukul Vehicle Parking Management System 1.13 at the time of the NVD entry. Operators should monitor the PHP Gurukul Security Resource for updates and consult the VulDB #316217 record for status changes.

Workarounds

Modify manage-category.php to use PHP Data Objects (PDO) prepared statements with bound parameters instead of string concatenation.
Cast the del parameter to an integer (intval($_GET['del'])) before use in the SQL query as a temporary hardening measure.
Disable or remove the category management functionality if it is not required for production operations.
