CVE-2025-41019: SISTICK v7.2 SQL Injection Vulnerability

CVE-2025-41019 Overview

A critical SQL injection vulnerability has been identified in Sergestec's SISTICK v7.2 ticketing system. This vulnerability allows an unauthenticated attacker to manipulate database operations through the id parameter in the /index.php?view=ticket_detail endpoint. Successful exploitation enables attackers to retrieve, create, update, and delete database contents, potentially compromising the entire backend data store.

Critical Impact

Unauthenticated attackers can fully compromise database integrity and confidentiality through SQL injection, enabling data exfiltration, modification, and destruction.

Technical Details for CVE-2025-41019

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) exists within the ticket detail viewing functionality of Sergestec's SISTICK application. The vulnerable endpoint /index.php?view=ticket_detail fails to properly sanitize or parameterize the id parameter before incorporating it into SQL queries. This classic injection flaw allows attackers to escape the intended query context and inject arbitrary SQL commands that execute with the privileges of the database user configured for the application.

The vulnerability is particularly severe because it requires no authentication to exploit. An attacker with network access to the application can craft malicious requests that manipulate the backend database. The full CRUD (Create, Read, Update, Delete) capabilities mean attackers can exfiltrate sensitive ticket data, customer information, and potentially authentication credentials stored in the database. Additionally, depending on database configuration and privileges, this could potentially be leveraged for further system compromise.

Root Cause

The root cause is improper input validation and the absence of parameterized queries (prepared statements) in the handling of the id parameter. The application directly concatenates user-supplied input into SQL query strings without sanitization, allowing SQL syntax to be injected and executed. This represents a failure to implement secure coding practices for database interaction.

Attack Vector

The attack is network-based and can be executed remotely without authentication. An attacker can send specially crafted HTTP requests to the vulnerable endpoint with a manipulated id parameter. The injection point is straightforward to identify and exploit.

For example, an attacker might manipulate a request to the ticket detail endpoint by injecting SQL syntax into the id parameter value. A simple test for vulnerability might involve appending a single quote or SQL comment syntax to observe application behavior. More sophisticated attacks would use UNION-based injection, error-based extraction, or blind SQL injection techniques to enumerate database structure, extract data, or modify records.

Technical exploitation details can be found in the INCIBE Security Notice.

Detection Methods for CVE-2025-41019

Indicators of Compromise

• Unusual or malformed requests to /index.php?view=ticket_detail containing SQL syntax characters such as single quotes, double dashes, semicolons, or UNION statements
• Database logs showing unexpected queries, errors, or access patterns originating from web application connections
• Evidence of data exfiltration or unauthorized database modifications in audit logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the id parameter and other user inputs
• Enable detailed logging on the web server and database to capture request parameters and query execution for forensic analysis
• Implement intrusion detection system (IDS) signatures to identify common SQL injection payloads targeting this endpoint

Monitoring Recommendations

• Monitor web server access logs for requests containing SQL injection indicators directed at /index.php
• Set up alerts for database errors or anomalous query patterns that may indicate injection attempts
• Review application logs regularly for signs of exploitation attempts or successful unauthorized data access

How to Mitigate CVE-2025-41019

Immediate Actions Required

• Restrict network access to the SISTICK application to trusted users and networks only until a patch is applied
• Implement WAF rules to filter SQL injection attempts targeting the id parameter
• Review database access privileges and ensure the application uses a least-privilege database account
• Audit database contents for signs of unauthorized access or modification

Patch Information

Organizations should consult Sergestec for official patches or updated versions of SISTICK that address this vulnerability. Refer to the INCIBE Security Notice for additional guidance and updates from the coordinating security organization.

Workarounds

• Deploy a Web Application Firewall with SQL injection protection rules in front of the SISTICK application
• Restrict access to the ticket detail functionality to authenticated and authorized users only through network segmentation or access controls
• If source code access is available, implement parameterized queries (prepared statements) for all database operations involving user input

# Example: Restrict access to SISTICK via iptables (allow only trusted IP)
iptables -A INPUT -p tcp --dport 80 -s 192.168.1.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
