CVE-2025-7456: Campcodes Movie Theater System SQLi Flaw

CVE-2025-7456 Overview

A critical SQL injection vulnerability has been identified in Campcodes Online Movie Theater Seat Reservation System version 1.0. The vulnerability exists in the /reserve.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data from the database, modify or delete records, and potentially gain further access to the underlying system.

Technical Details for CVE-2025-7456

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation in the /reserve.php endpoint. When the application processes the ID parameter, it fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are executed by the database server with the same privileges as the application's database user.

The vulnerability is network-accessible, requiring no authentication or user interaction to exploit. This makes it particularly dangerous as any remote attacker can target exposed instances of the application. The exploit has been publicly disclosed, increasing the risk of widespread exploitation.

Root Cause

The root cause of CVE-2025-7456 is improper input validation (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component). The application directly incorporates user-controlled input from the ID parameter into SQL queries without proper sanitization, parameterization, or prepared statements. This fundamental security oversight allows attackers to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack vector for this vulnerability is network-based, allowing remote exploitation. An attacker can craft malicious HTTP requests to the /reserve.php endpoint with specially crafted ID parameter values containing SQL injection payloads.

The exploitation technique involves manipulating the ID parameter to include SQL syntax that alters the intended query logic. Common attack patterns include:

Using single quotes or double quotes to break out of string contexts
Employing UNION-based injection to extract data from other tables
Utilizing boolean-based or time-based blind injection techniques for data exfiltration
Leveraging stacked queries to execute additional SQL statements

For detailed technical analysis, refer to the GitHub Issue Discussion and VulDB entry #316100.

Detection Methods for CVE-2025-7456

Indicators of Compromise

Unusual or malformed requests to /reserve.php containing SQL syntax in the ID parameter
Database error messages in application logs indicating syntax errors or unexpected query behavior
Abnormal database query patterns including UNION SELECT statements, time-based delays, or multiple semicolons
Evidence of data exfiltration or unauthorized database access in audit logs

Detection Strategies

Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in HTTP parameters
Implement application-level logging for all database queries with parameter values to identify injection attempts
Monitor for anomalous database activity such as bulk data reads, schema enumeration, or privilege escalation attempts
Configure intrusion detection systems (IDS) to alert on SQL injection signatures in network traffic targeting the /reserve.php endpoint

Monitoring Recommendations

Enable detailed access logging for the web application and correlate with database query logs
Set up real-time alerting for requests containing SQL metacharacters in the ID parameter
Monitor database server performance for unusual spikes that may indicate time-based blind injection attacks
Implement database activity monitoring (DAM) to track all queries executed against sensitive tables

How to Mitigate CVE-2025-7456

Immediate Actions Required

Take the affected Online Movie Theater Seat Reservation System offline or restrict network access until remediation is complete
Review database logs for evidence of prior exploitation and assess potential data compromise
Implement Web Application Firewall rules to block SQL injection attempts targeting /reserve.php
If possible, apply input validation at the network perimeter to filter malicious requests

Patch Information

At the time of writing, no official patch has been released by Campcodes for this vulnerability. Organizations should monitor the Campcodes website for security updates. Given the critical nature of this vulnerability and the lack of a vendor patch, organizations should strongly consider implementing workarounds or replacing the affected software with a secure alternative.

Workarounds

Implement strict input validation for the ID parameter, allowing only numeric values
Deploy a Web Application Firewall configured to detect and block SQL injection payloads
Restrict network access to the application using firewall rules to limit exposure to trusted networks only
If source code access is available, modify /reserve.php to use parameterized queries or prepared statements
