CVE-2025-41002: Infoticketing SQL Injection Vulnerability

CVE-2025-41002 Overview

CVE-2025-41002 is a critical SQL injection vulnerability affecting Infoticketing, a ticketing and cart management application. This vulnerability allows an unauthenticated attacker to retrieve, create, update, and delete database contents by sending a malicious POST request using the code parameter in /components/cart/cartApplyDiscount.php.

The flaw stems from improper input validation in the discount code application functionality, enabling attackers to manipulate SQL queries and gain unauthorized access to the underlying database. Since no authentication is required to exploit this vulnerability, it poses a significant risk to organizations using affected Infoticketing deployments.

Critical Impact

Unauthenticated attackers can fully compromise database integrity and confidentiality through SQL injection, potentially leading to complete data breach, data manipulation, or destruction.

Affected Products

• Infoticketing (specific versions not disclosed)
• Infoticketing cart module (/components/cart/cartApplyDiscount.php)

Technical Details for CVE-2025-41002

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists within the cart discount application functionality of Infoticketing. The vulnerable endpoint /components/cart/cartApplyDiscount.php accepts POST requests containing a code parameter that is directly incorporated into SQL queries without proper sanitization or parameterization.

When a user submits a discount code, the application constructs a database query to validate the code. Due to insufficient input validation, an attacker can inject arbitrary SQL statements through the code parameter, bypassing the intended query logic entirely.

The vulnerability enables full database manipulation capabilities including:

• Data Exfiltration: Retrieving sensitive customer information, payment details, and business data
• Data Modification: Altering pricing, inventory, or user account information
• Data Destruction: Deleting critical records or entire database tables
• Privilege Escalation: Creating administrative accounts or modifying user permissions

Root Cause

The root cause is improper input validation and the failure to use parameterized queries or prepared statements when handling user-supplied input. The code parameter from POST requests is concatenated directly into SQL query strings rather than being treated as data, allowing SQL metacharacters to alter query structure.

Attack Vector

The attack is network-based and requires no authentication or user interaction. An attacker can craft a malicious HTTP POST request to the vulnerable endpoint, injecting SQL statements through the code parameter.

The exploitation flow involves sending specially crafted input containing SQL syntax that breaks out of the intended query context, allowing the attacker to append arbitrary SQL commands. Common techniques include UNION-based injection to extract data, stacked queries for data modification, or time-based blind injection when direct output is not available.

For technical details on the vulnerability mechanism, refer to the INCIBE Security Notice on SQL Injection.

Detection Methods for CVE-2025-41002

Indicators of Compromise

• Unusual POST requests to /components/cart/cartApplyDiscount.php containing SQL metacharacters (e.g., single quotes, UNION, SELECT, OR 1=1)
• Database query logs showing unexpected queries originating from the cart discount functionality
• Anomalous database access patterns including bulk data extraction or modification operations
• Error logs containing SQL syntax errors or database exceptions from the cartApplyDiscount endpoint

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in POST parameters targeting /components/cart/cartApplyDiscount.php
• Monitor application logs for requests containing common SQL injection payloads in the code parameter
• Implement database activity monitoring to detect unauthorized queries, mass data extraction, or schema enumeration
• Configure alerting for failed login attempts or privilege escalation following suspicious cart-related requests

Monitoring Recommendations

• Enable verbose logging for the Infoticketing cart module to capture all incoming requests and parameter values
• Set up real-time alerts for any database errors originating from discount code validation queries
• Monitor network traffic for exfiltration patterns following requests to the vulnerable endpoint
• Review database audit logs regularly for signs of data manipulation or unauthorized access

How to Mitigate CVE-2025-41002

Immediate Actions Required

• Restrict or disable access to /components/cart/cartApplyDiscount.php until a patch can be applied
• Implement input validation at the network perimeter using WAF rules to filter SQL injection attempts
• Add authentication requirements to the vulnerable endpoint as a temporary control
• Audit database logs for signs of prior exploitation and assess potential data compromise

Patch Information

Consult the vendor or the INCIBE Security Notice for official patch availability and update instructions. Organizations should apply vendor-provided security updates as soon as they become available.

Workarounds

• Deploy a Web Application Firewall with SQL injection detection rules specifically targeting the code parameter
• Implement strict input validation on the code parameter, allowing only alphanumeric characters expected for discount codes
• Temporarily disable the discount code functionality if it is not business-critical
• Restrict network access to the application to trusted IP ranges while awaiting an official patch
