CVE-2025-4777: Park Ticketing Management System SQLi Flaw

CVE-2025-4777 Overview

CVE-2025-4777 is a SQL injection vulnerability in PHPGurukul Park Ticketing Management System 2.0. The flaw resides in the /view-foreigner-ticket.php script, where the viewid parameter is passed to a database query without proper sanitization. Authenticated remote attackers can manipulate the viewid argument to inject arbitrary SQL statements. The exploit details have been publicly disclosed, increasing the likelihood of opportunistic attacks against exposed installations. This issue is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization in Output Used by a Downstream Component).

Critical Impact
Successful exploitation allows attackers to read, modify, or delete records in the park ticketing database, including visitor and ticket data.

Affected Products

Technical Details for CVE-2025-4777

Vulnerability Analysis

The vulnerability exists in the view-foreigner-ticket.php endpoint of PHPGurukul Park Ticketing Management System 2.0. The script accepts a viewid GET parameter and concatenates the value directly into an SQL statement executed against the backend database. Because the application does not validate or parameterize the input, an attacker can break out of the intended query context and append arbitrary SQL clauses. Exploitation can be performed remotely over the network with low-privilege application credentials. The reference disclosure is documented in the GitHub Issue Discussion and VulDB #309075.

Root Cause

The root cause is the absence of prepared statements or input sanitization on the viewid parameter. PHPGurukul concatenates user-controlled input into the SQL query string, allowing the injected payload to be parsed as SQL syntax. This pattern is common across PHPGurukul applications that rely on mysqli_query without parameter binding.

Attack Vector

An authenticated attacker sends a crafted HTTP request to /view-foreigner-ticket.php with a malicious viewid value. Typical payloads use UNION-based or boolean-based injection techniques to enumerate database schema, extract credentials, or exfiltrate ticket records. The attack requires no user interaction and no elevated privileges beyond an application login. A representative request pattern targets the parameter with an appended UNION SELECT clause to retrieve data from other tables, as described in the public disclosure.

Detection Methods for CVE-2025-4777

Indicators of Compromise

HTTP requests to /view-foreigner-ticket.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( in the viewid parameter
Web server logs showing repeated requests to view-foreigner-ticket.php with anomalous viewid values from a single source
Database error messages referencing syntax errors near user-supplied values in application logs

Detection Strategies

Deploy web application firewall (WAF) rules that flag SQL injection signatures targeting the viewid parameter
Apply OWASP Core Rule Set rule families 942xxx for SQL injection identification on PHPGurukul endpoints
Correlate application access logs with database query logs to identify malformed queries originating from the ticketing module

Monitoring Recommendations

Enable verbose query logging on the MySQL/MariaDB backend to capture suspicious SELECT patterns
Monitor for outbound data flows from the database server that exceed normal ticket-query volume
Alert on authentication failures followed by successful logins and immediate access to /view-foreigner-ticket.php

How to Mitigate CVE-2025-4777

Immediate Actions Required

Restrict access to /view-foreigner-ticket.php to trusted internal networks until a fix is applied
Audit the application database for unauthorized read or write activity since deployment
Rotate database credentials and any administrative passwords stored in the affected database

Patch Information

No official vendor patch has been published in the referenced advisories at the time of NVD update. Administrators should monitor the PHP Gurukul Resource site and the VulDB #309075 CTI entry for fix releases. Until a vendor patch is available, apply source-level remediation by replacing concatenated SQL with parameterized queries using mysqli_prepare or PDO prepared statements.

Workarounds

Implement server-side input validation that restricts viewid to numeric values only
Deploy a WAF in front of the application with SQL injection signatures enabled in blocking mode
Run the application database account with least-privilege permissions, removing FILE, CREATE, and write access where not required

bash

# Example Apache mod_rewrite rule to enforce numeric viewid values
RewriteEngine On
RewriteCond %{QUERY_STRING} (^|&)viewid=([^0-9&]+) [NC]
RewriteRule ^view-foreigner-ticket\.php$ - [F,L]
