CVE-2026-7074: Construction Management System SQL Injection

CVE-2026-7074 Overview

A SQL injection vulnerability has been discovered in itsourcecode Construction Management System version 1.0. This vulnerability affects the file /execute1.php where improper handling of the code parameter allows remote attackers to inject malicious SQL queries. The attack can be performed remotely without authentication, and exploit details have been publicly disclosed.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database records, or potentially gain unauthorized access to the underlying system through the publicly exposed /execute1.php endpoint.

Affected Products

• itsourcecode Construction Management System 1.0
• /execute1.php endpoint with code parameter

Technical Details for CVE-2026-7074

Vulnerability Analysis

This vulnerability represents a classic SQL injection flaw (CWE-74) in a web-based construction management application. The /execute1.php file fails to properly sanitize user-supplied input passed through the code parameter before incorporating it into SQL queries. This lack of input validation allows attackers to manipulate the query structure, potentially bypassing authentication controls, extracting sensitive project and user data, or executing administrative database operations.

The network-accessible nature of this vulnerability means that any attacker with network access to the application can attempt exploitation without requiring any prior authentication or user interaction. The impact includes potential compromise of data confidentiality, integrity, and availability within the application's database.

Root Cause

The root cause of this vulnerability is insufficient input validation and the absence of parameterized queries or prepared statements in the /execute1.php file. The application directly concatenates user-supplied data from the code parameter into SQL query strings, allowing specially crafted input to alter the intended query logic.

Attack Vector

The attack is conducted remotely over the network by sending a crafted HTTP request to the /execute1.php endpoint. An attacker manipulates the code parameter to inject SQL syntax that modifies the query behavior. Common attack techniques include using SQL operators like UNION SELECT, boolean-based blind injection, or time-based blind injection to enumerate database contents or bypass authentication.

The vulnerability mechanism involves the application accepting untrusted input through the code parameter and directly incorporating it into database queries without proper sanitization or the use of prepared statements. Attackers can craft malicious input containing SQL metacharacters and commands that are then executed by the database server.

Detection Methods for CVE-2026-7074

Indicators of Compromise

• HTTP requests to /execute1.php containing SQL injection patterns such as single quotes, UNION, SELECT, OR 1=1, or encoded SQL commands in the code parameter
• Unusual database query errors or timeout patterns in application logs
• Unexpected data extraction or modification activities in database audit logs
• Web application firewall (WAF) alerts for SQL injection attempts targeting the affected endpoint

Detection Strategies

• Implement web application firewall rules to detect and block SQL injection patterns in requests to /execute1.php
• Monitor HTTP access logs for requests containing suspicious patterns in the code parameter
• Enable database query logging and alert on anomalous query patterns or syntax errors
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack vectors

Monitoring Recommendations

• Configure real-time alerting for any requests to /execute1.php containing SQL metacharacters
• Establish baseline database activity patterns and alert on deviations
• Review web server access logs regularly for reconnaissance and exploitation attempts
• Monitor for data exfiltration indicators such as large response sizes or unusual query result sets

How to Mitigate CVE-2026-7074

Immediate Actions Required

• Restrict access to /execute1.php via network segmentation or firewall rules until a patch is available
• Implement a web application firewall (WAF) with SQL injection protection rules
• Review and audit all input handling in /execute1.php and related files
• Consider temporarily disabling the affected functionality if not business-critical

Patch Information

No official vendor patch information is currently available for this vulnerability. Organizations should monitor the IT Source Code Resource website for updates. In the meantime, implement the workarounds and detection strategies outlined below. For additional vulnerability details, consult VulDB Vulnerability #359649.

Workarounds

• Implement input validation to reject or sanitize SQL metacharacters in the code parameter
• Use parameterized queries or prepared statements to prevent SQL injection
• Apply the principle of least privilege to database accounts used by the application
• Deploy a WAF configured to block common SQL injection attack patterns
• Restrict network access to the application to trusted IP ranges where feasible

If modifying source code is an option, the recommended approach is to refactor /execute1.php to use parameterized queries or prepared statements. All user input should be validated against an allowlist of expected values before being used in database operations. Database connections should use accounts with minimal required privileges to limit the impact of successful exploitation.
