CVE-2025-7491 Overview
CVE-2025-7491 is a SQL injection vulnerability in PHPGurukul Vehicle Parking Management System version 1.13. The flaw resides in the /admin/manage-outgoingvehicle.php script, where the del parameter is passed directly into a database query without sanitization. Authenticated attackers can manipulate this parameter over the network to inject arbitrary SQL statements. The issue is classified under [CWE-74] as improper neutralization of special elements in output used by a downstream component. Public exploit details have been disclosed, increasing the risk of opportunistic abuse against exposed installations.
Critical Impact
Remote attackers with low-privileged access can inject SQL statements through the del parameter, potentially reading, modifying, or deleting database contents in the vehicle parking management backend.

Technical Details for CVE-2025-7491
Vulnerability Analysis
The vulnerability affects the administrative interface used to manage outgoing vehicle records. The del parameter, typically used to specify a record identifier for deletion, is concatenated into a SQL statement without prepared statements or input validation. This allows an authenticated administrator-level user to alter the query logic and execute arbitrary SQL against the underlying MySQL database. Because the application accepts requests remotely, exploitation does not require local access to the host.
Root Cause
The root cause is improper neutralization of user-supplied input passed to a SQL query [CWE-74]. The del parameter arrives via an HTTP request and is inserted into a DELETE or SELECT statement without parameterization. PHP's mysqli or PDO prepared statement APIs are not used, and no allow-list validation is applied to the value.
Attack Vector
An attacker with valid admin session credentials sends a crafted HTTP request to /admin/manage-outgoingvehicle.php with a malicious value in the del parameter. The injected payload can use standard SQL injection techniques such as UNION SELECT clauses, boolean-based blind extraction, or time-based delays to enumerate database contents. Successful exploitation can expose vehicle records, user credentials stored in the database, or allow tampering with parking records.

Detection Methods for CVE-2025-7491
Indicators of Compromise
- HTTP requests to /admin/manage-outgoingvehicle.php containing SQL metacharacters such as ', --, UNION, SLEEP(, or BENCHMARK( in the del parameter.
- Unexpected database errors or long response times from the admin endpoint, indicating blind SQL injection probing.
- Access to the admin path from IP addresses not associated with legitimate administrator activity.
Detection Strategies
- Deploy a web application firewall (WAF) rule set that inspects query strings and POST bodies for SQL injection patterns targeting the del parameter.
- Enable verbose MySQL query logging on the parking system database and review queries containing concatenated user input.
- Correlate web server access logs with database error logs to identify malformed SQL originating from manage-outgoingvehicle.php.
Monitoring Recommendations
- Alert on repeated 500-series HTTP responses from /admin/manage-outgoingvehicle.php, which often accompany injection probing.
- Monitor for anomalous outbound data volumes from the database host, which may indicate mass record extraction.
- Track admin authentication events and flag concurrent sessions or logins from unexpected geolocations.
How to Mitigate CVE-2025-7491
Immediate Actions Required
- Restrict network access to the /admin/ directory using IP allow-listing or VPN-only access until a fix is applied.
- Rotate administrator credentials and audit admin accounts for unauthorized additions.
- Review database contents for signs of unauthorized modification or exfiltration.
Patch Information
No official vendor patch is currently referenced in the NVD advisory for CVE-2025-7491. Users of PHPGurukul Vehicle Parking Management System 1.13 should monitor the PHPGurukul website for security updates and consider migrating to an actively maintained parking management platform if no patch is issued.
Workarounds
- Modify the affected PHP source to use parameterized queries via mysqli_prepare() or PDO prepared statements for the del parameter.
- Add server-side validation to ensure del accepts only positive integer values, rejecting all other input.
- Place the application behind a WAF with SQL injection signatures enabled and block requests containing SQL metacharacters targeting admin endpoints.
