CVE-2025-4778: Park Ticketing Management System SQLi Flaw

CVE-2025-4778 Overview

CVE-2025-4778 is a SQL injection vulnerability in PHPGurukul Park Ticketing Management System 2.0. The flaw resides in /normal-search.php, where the searchdata parameter is passed directly into a database query without proper sanitization. Attackers can manipulate the parameter to inject arbitrary SQL statements and influence query logic.

The vulnerability is exploitable remotely over the network and requires only low-privileged authentication. A proof-of-concept exploit has been disclosed publicly, increasing the likelihood of opportunistic attacks against exposed installations. The issue maps to [CWE-89] (SQL Injection) and [CWE-74] (Improper Neutralization of Special Elements).

Critical Impact
Remote attackers with low privileges can inject SQL through the searchdata parameter to read, modify, or expose data managed by the ticketing application.

Technical Details for CVE-2025-4778

Vulnerability Analysis

The vulnerability exists in the search handler implemented in /normal-search.php. The application accepts a user-supplied searchdata value from an HTTP request and concatenates it into a backend SQL statement without parameterization or input validation. This allows the attacker-controlled string to break out of the intended query context and append additional SQL clauses.

Because the affected endpoint is reachable over the network and requires only low-privileged access, an authenticated user of the ticketing portal can submit crafted search input to alter query semantics. The vulnerability impacts the confidentiality, integrity, and availability of the underlying database in a limited fashion, consistent with a partial SQL injection scenario.

A public disclosure on the GitHub Issue Discussion describes the exploitation path, and VulDB #309076 tracks the issue with additional threat intelligence.

Root Cause

The root cause is improper neutralization of special elements used in SQL commands [CWE-89]. The searchdata argument flows from request input into a dynamically constructed query string. The application does not use prepared statements, parameterized queries, or input escaping appropriate for the database driver in use.

Attack Vector

An attacker submits a crafted HTTP request to /normal-search.php with a malicious searchdata payload. The injected SQL fragment executes within the application's database context. Typical payloads include boolean-based, UNION-based, or time-based injections used to enumerate schemas, extract records, or infer database contents.

The vulnerability manifests when user-controlled input is concatenated directly into a SQL SELECT statement filtering ticket records. See the VulDB CTI #309076 entry for technical context.

Detection Methods for CVE-2025-4778

Indicators of Compromise

HTTP requests to /normal-search.php containing SQL metacharacters such as single quotes, UNION SELECT, OR 1=1, or SQL comment sequences (--, #) in the searchdata parameter.
Unexpected database errors or anomalously long response times tied to search requests, suggesting time-based blind injection attempts.
Web server logs showing repeated searchdata requests from a single source enumerating tables or columns.

Detection Strategies

Deploy web application firewall (WAF) rules to flag SQL injection signatures targeting the searchdata parameter.
Enable database query logging and alert on queries originating from the application that contain anomalous syntax or reference information_schema.
Review application access logs for GET or POST requests to /normal-search.php with encoded payloads such as %27, %20OR%20, or %23.

Monitoring Recommendations

Forward web server, application, and database logs to a centralized analytics platform for correlation of injection attempts with downstream query anomalies.
Establish baselines for normal searchdata parameter length and character set, alerting on deviations.
Track authentication events preceding suspicious search requests to identify potentially compromised low-privileged accounts.

How to Mitigate CVE-2025-4778

Immediate Actions Required

Restrict network exposure of the Park Ticketing Management System to trusted users and networks until a patch is applied.
Audit application accounts and revoke unnecessary low-privileged access that could be used to reach /normal-search.php.
Deploy WAF signatures blocking SQL injection patterns directed at the searchdata parameter.
Review database logs for prior exploitation indicators, including unexpected UNION queries or schema enumeration.

Patch Information

No official vendor advisory or patch is referenced in the disclosure data. Refer to the PHP Gurukul Security Resource for vendor updates and to the VulDB Submission #572161 for tracking. Until a fix is published, apply compensating controls listed below and consider replacing the vulnerable search handler with a parameterized implementation if source modification is permitted.

Workarounds

Rewrite the affected query in /normal-search.php to use parameterized statements or prepared queries via PDO or MySQLi with bound parameters.
Apply strict server-side input validation on searchdata, allowing only expected characters such as alphanumerics and whitespace.
Enforce least-privilege database accounts so the application user cannot read system schemas or write to sensitive tables.
Disable verbose database error reporting in production to reduce information leakage during injection attempts.
