CVE-2025-4770: Park Ticketing Management System SQL Injection

CVE-2025-4770 Overview

CVE-2025-4770 is a SQL injection vulnerability in PHPGurukul Park Ticketing Management System 2.0. The flaw resides in the /view-normal-ticket.php script, where the viewid parameter is incorporated into 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 likelihood of opportunistic abuse against exposed deployments. The vulnerability maps to CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization).

Critical Impact
Remote attackers with low privileges can extract, modify, or delete records in the ticketing system database through the vulnerable viewid parameter.

Technical Details for CVE-2025-4770

Vulnerability Analysis

The vulnerability exists in the /view-normal-ticket.php endpoint of PHPGurukul Park Ticketing Management System 2.0. The script accepts a viewid request parameter and concatenates the value directly into an SQL query. Because the input is not parameterized or escaped, attackers can supply crafted payloads that alter the query structure. A successful attack lets an adversary read or modify data outside the intended scope of the request. The EPSS score is 0.197% with a percentile of 41.65, indicating low but non-negligible exploitation probability.

Root Cause

The root cause is improper neutralization of user-controllable input prior to query construction. The application passes the viewid parameter into a MySQL query string without prepared statements or input validation. PHP database access in the affected script relies on string concatenation, which allows query operators and comment sequences supplied by the user to break out of the original query context.

Attack Vector

Attacks originate over the network against the web interface. The attacker submits a request to /view-normal-ticket.php with a malicious viewid value. Low-privilege authenticated access is required to reach the endpoint. Public disclosure on the GitHub issue tracker and VulDB entry #309071 provides enough detail to reproduce the issue.

No verified proof-of-concept code is being reproduced here. Refer to the VulDB CTI Report #309071 and the GitHub Issue Discussion for technical details on the payload structure.

Detection Methods for CVE-2025-4770

Indicators of Compromise

Web server access logs containing requests to /view-normal-ticket.php with SQL metacharacters such as single quotes, UNION, SELECT, --, or /* in the viewid parameter.
Unexpected database errors in PHP error logs originating from the ticketing application.
Anomalous outbound queries from the database server or large result sets returned to the web tier.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the viewid parameter for SQL injection patterns.
Enable MySQL general query logging on the ticketing database and alert on queries containing UNION-based or boolean-based injection signatures.
Correlate HTTP 500 responses from /view-normal-ticket.php with subsequent successful 200 responses from the same source IP, which can indicate iterative payload tuning.

Monitoring Recommendations

Forward web server, PHP, and MySQL logs to a centralized analytics platform for query and pattern analysis.
Baseline normal viewid values (numeric integers) and alert on any non-numeric input.
Monitor authentication logs for low-privilege accounts performing unusual ticket lookup volumes.

How to Mitigate CVE-2025-4770

Immediate Actions Required

Restrict network access to the Park Ticketing Management System to trusted users until a fix is applied.
Place a WAF in front of the application with rules blocking SQL injection patterns on the viewid parameter.
Audit ticketing database accounts and rotate credentials if logs indicate suspicious queries.

Patch Information

No vendor patch has been published in the references available for CVE-2025-4770. Operators should monitor the PHPGurukul website for an updated release. Until a patch is available, apply code-level fixes that replace string concatenation with prepared statements using mysqli or PDO bound parameters, and validate that viewid is an integer before use.

Workarounds

Modify /view-normal-ticket.php to cast viewid to an integer with intval() before using it in any SQL statement.
Apply server-side input validation that rejects requests where viewid contains non-numeric characters.
Limit the database account used by the application to read-only privileges on the minimum tables required.
