CVE-2025-7522: Vehicle Parking Management System SQLi Flaw

CVE-2025-7522 Overview

CVE-2025-7522 is a SQL injection vulnerability in PHPGurukul Vehicle Parking Management System version 1.13. The flaw resides in /admin/bwdates-reports-details.php, where the fromdate and todate parameters are concatenated into SQL queries without proper sanitization. An authenticated attacker with low privileges can manipulate these parameters to inject arbitrary SQL statements. The attack is launchable remotely over the network, and the exploit has been publicly disclosed. The vulnerability is tracked under CWE-74 (Improper Neutralization of Special Elements in Output).

Critical Impact
Remote attackers with authenticated admin-area access can manipulate database queries through the date-range report functionality, potentially exposing or modifying parking management records.

Technical Details for CVE-2025-7522

Vulnerability Analysis

The vulnerability exists in the date-range reporting feature of the admin panel. The script /admin/bwdates-reports-details.php accepts fromdate and todate parameters via HTTP request and uses them to build a SQL query that filters parking records by date.

Because the input is concatenated directly into the query string without parameterized statements or input validation, an attacker can inject SQL syntax. This breaks the intended query structure and allows arbitrary SQL execution against the backend MySQL database. The vulnerability falls under CWE-74, covering improper neutralization of special elements.

The affected report functionality is typically reachable by users with administrative session access. Combined with weak authentication patterns common in PHPGurukul applications, the attack surface is meaningful for any internet-exposed deployment.

Root Cause

The root cause is the absence of prepared statements or input validation in the bwdates-reports-details.php script. User-supplied date values are passed directly into the SQL query string. PHP's mysqli or mysql_query functions execute the resulting statement without distinguishing user input from query structure.

Attack Vector

The attacker submits a crafted HTTP request to the /admin/bwdates-reports-details.php endpoint with malicious payloads in the fromdate or todate POST or GET parameters. Typical payloads use UNION-based or boolean-based injection techniques to extract data such as administrator credentials, vehicle records, or session identifiers. Time-based blind injection is also feasible when error output is suppressed. The exploit is publicly documented in the GitHub Issue Discussion and cataloged in VulDB #316219.

The vulnerability mechanism is described in the referenced advisory. No verified exploit code is reproduced here.

Detection Methods for CVE-2025-7522

Indicators of Compromise

HTTP requests to /admin/bwdates-reports-details.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the fromdate or todate parameters.
Unexpected database error messages logged from the PHP application referencing syntax errors on the parking management database.
Anomalous outbound queries from the web server to the database returning unusually large result sets.
New or unexpected administrative accounts appearing in the admin table.

Detection Strategies

Inspect web server access logs for date parameters containing non-date characters or URL-encoded SQL keywords.
Deploy a web application firewall rule that flags SQL syntax in parameters expected to match date formats such as YYYY-MM-DD.
Enable MySQL general query logging and review queries originating from the reports module for malformed WHERE clauses.

Monitoring Recommendations

Monitor authentication events on the /admin/ path for credential stuffing or brute-force activity that could precede exploitation.
Track query volume and execution time spikes on the parking records database, which can indicate blind injection probing.
Alert on UNION SELECT patterns appearing in HTTP request bodies destined for the application.

How to Mitigate CVE-2025-7522

Immediate Actions Required

Restrict access to the /admin/ directory using IP allow-listing or VPN-only access until a patch is applied.
Audit the admin user table and reset all administrative credentials.
Review database logs for evidence of prior exploitation against the reports endpoint.
Deploy a WAF signature blocking SQL metacharacters in the fromdate and todate parameters.

Patch Information

No official vendor patch is currently listed in the references. Administrators should monitor the PHP Gurukul Resource and the GitHub Issue Discussion for vendor remediation guidance. As an interim fix, modify bwdates-reports-details.php to use parameterized queries with mysqli_prepare and bind the date parameters as strings.

Workarounds

Replace direct query concatenation in bwdates-reports-details.php with prepared statements using mysqli::prepare and bind_param.
Add server-side regex validation rejecting any fromdate or todate value that does not match the ^\d{4}-\d{2}-\d{2}$ pattern.
Apply database least-privilege so the application user cannot execute DROP, ALTER, or access tables outside the parking schema.
Disable detailed PHP and MySQL error reporting in production to limit information disclosure during injection attempts.

bash

# Example Apache mod_security rule to reject non-date input on the vulnerable parameters
SecRule ARGS:fromdate|ARGS:todate "!@rx ^\d{4}-\d{2}-\d{2}$" \
