CVE-2026-7075: Construction Management System SQLi Flaw

CVE-2026-7075 Overview

A SQL Injection vulnerability has been identified in itsourcecode Construction Management System version 1.0. This issue affects the processing of the file /locations.php, where manipulation of the address argument enables SQL injection attacks. The vulnerability can be exploited remotely without authentication, and the exploit has been publicly disclosed.

Critical Impact
Remote attackers can manipulate database queries through the address parameter in /locations.php, potentially leading to unauthorized data access, data modification, or data destruction.

Technical Details for CVE-2026-7075

Vulnerability Analysis

This SQL Injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) exists in the /locations.php file of itsourcecode Construction Management System. The application fails to properly sanitize user-supplied input in the address parameter before incorporating it into SQL queries. This lack of input validation allows an attacker to inject malicious SQL statements that are then executed by the database server.

The vulnerability is remotely exploitable and requires no authentication or user interaction, making it accessible to any network-based attacker. Successful exploitation could allow attackers to read sensitive data from the database, modify or delete records, and potentially execute administrative operations on the database.

Root Cause

The root cause of this vulnerability is improper input validation and failure to use parameterized queries or prepared statements. The address parameter in /locations.php is directly concatenated into SQL queries without proper sanitization or escaping, allowing special SQL characters and commands to be interpreted by the database engine. This represents a classic injection vulnerability pattern where untrusted input is used to construct database queries.

Attack Vector

The attack is conducted over the network, targeting the /locations.php endpoint. An attacker can craft malicious input for the address parameter containing SQL metacharacters and injection payloads. When the vulnerable application processes this input, the injected SQL code is executed against the backend database.

Typical exploitation techniques include using UNION-based injection to extract data from other tables, boolean-based blind injection to enumerate database contents one bit at a time, or time-based blind injection using database-specific delay functions. The attacker does not require any privileges or user interaction to exploit this vulnerability.

Detection Methods for CVE-2026-7075

Indicators of Compromise

Unusual or malformed requests to /locations.php containing SQL metacharacters such as single quotes, semicolons, or comment sequences (--, /**/)
Database error messages appearing in application logs or HTTP responses
Unexpected database queries containing UNION SELECT, SLEEP(), BENCHMARK(), or information_schema references
Abnormal database access patterns or data exfiltration from the application database

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /locations.php
Enable verbose logging for the web server and database server to capture suspicious query patterns
Deploy intrusion detection signatures for common SQL injection payloads targeting the address parameter
Monitor for error-based SQL injection indicators in HTTP responses

Monitoring Recommendations

Set up real-time alerting for requests containing SQL injection indicators targeting /locations.php
Monitor database query logs for anomalous queries or unauthorized data access attempts
Track HTTP 500 errors or database error messages that may indicate injection attempts
Review access logs for repeated requests to /locations.php with varying address parameter values

How to Mitigate CVE-2026-7075

Immediate Actions Required

Restrict network access to the Construction Management System to trusted networks only
Implement input validation to reject requests containing SQL metacharacters in the address parameter
Deploy a Web Application Firewall with SQL injection protection rules enabled
Consider taking the affected system offline until a patch is available

Patch Information

No vendor patch information is currently available. Organizations should monitor the IT Source Code Resource for updates. Additional vulnerability details can be found in the VulDB Vulnerability #359650 entry and the GitHub Issue Tracking report.

Workarounds

Implement parameterized queries or prepared statements in the vulnerable code section of /locations.php
Apply strict input validation to whitelist acceptable characters for the address parameter
Use a Web Application Firewall to filter and block SQL injection attempts
Limit database user privileges to the minimum required for application functionality
Enable database query logging and monitoring for anomaly detection
