CVE-2026-6007: Construction Management System SQLi Flaw

CVE-2026-6007 Overview

A SQL injection vulnerability has been identified in itsourcecode Construction Management System version 1.0. This vulnerability affects the /del.php file, where improper handling of the equipname parameter allows attackers to inject malicious SQL commands. The vulnerability can be exploited remotely by authenticated users, potentially leading to unauthorized data access, modification, or deletion within the application's database.

Critical Impact

Remote attackers can exploit this SQL injection flaw to manipulate database queries, potentially extracting sensitive construction project data, user credentials, or performing unauthorized data modifications.

Affected Products

• itsourcecode Construction Management System 1.0
• /del.php endpoint with equipname parameter

Technical Details for CVE-2026-6007

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) exists within the Construction Management System's equipment deletion functionality. The /del.php file accepts user-supplied input through the equipname parameter without proper sanitization or parameterized query handling. This allows attackers to craft malicious input that breaks out of the intended SQL query context and executes arbitrary database commands.

The vulnerability requires low privileges to exploit and does not require user interaction. Successful exploitation can compromise the confidentiality, integrity, and availability of the application's data, though the impact is limited in scope to the vulnerable component itself.

Root Cause

The root cause of this vulnerability is improper input validation and the use of unsanitized user input directly in SQL queries. The equipname parameter value is concatenated into SQL statements without proper escaping, prepared statements, or parameterized queries. This allows special SQL characters and commands to be interpreted as part of the query structure rather than as data values.

Attack Vector

The attack vector is network-based, allowing remote exploitation with low complexity. An authenticated attacker can manipulate the equipname parameter in HTTP requests to the /del.php endpoint. By injecting SQL metacharacters such as single quotes, semicolons, or SQL keywords like UNION, SELECT, or OR, the attacker can alter the query logic to:

• Bypass deletion restrictions
• Extract data from other database tables
• Modify or delete arbitrary records
• Potentially escalate to further system compromise depending on database configuration

The vulnerability has been publicly disclosed, with technical details available through the GitHub Issue Submission and VulDB #356563 Vulnerability entries.

Detection Methods for CVE-2026-6007

Indicators of Compromise

• Unusual or malformed requests to /del.php containing SQL metacharacters in the equipname parameter
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database query patterns or data exfiltration attempts
• Access logs showing repeated requests to /del.php with varying equipname values

Detection Strategies

• Implement web application firewall (WAF) rules to detect SQL injection patterns in HTTP parameters
• Monitor application logs for requests containing common SQL injection payloads such as ' OR 1=1, UNION SELECT, or comment sequences (--, /*)
• Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
• Enable database query logging and alert on anomalous query structures or unauthorized data access

Monitoring Recommendations

• Configure real-time alerting for SQL error messages in application logs
• Establish baseline metrics for /del.php endpoint usage and alert on deviations
• Monitor database audit logs for unexpected SELECT, UPDATE, or DELETE operations
• Implement network traffic analysis to detect data exfiltration patterns

How to Mitigate CVE-2026-6007

Immediate Actions Required

• Restrict access to the /del.php endpoint through network segmentation or access controls
• Implement input validation to sanitize the equipname parameter before processing
• Consider temporarily disabling the equipment deletion functionality until a proper fix is applied
• Review database permissions to ensure the application uses a least-privilege database account

Patch Information

As of the last NVD update on 2026-04-13, no official vendor patch has been released for this vulnerability. Organizations using itsourcecode Construction Management System 1.0 should monitor the Itsourcecode website for security updates. Additional vulnerability details are available through VulDB #356563 CTI Info.

Workarounds

• Implement prepared statements or parameterized queries in the /del.php file to prevent SQL injection
• Deploy a web application firewall (WAF) with SQL injection protection rules in front of the application
• Apply strict input validation to reject any equipname values containing SQL metacharacters
• Limit database user permissions to only the minimum required operations for the application

Organizations should apply defense-in-depth measures including input validation at the application layer combined with WAF protection at the network layer. Database-level controls such as restricted user permissions and query logging provide additional security layers while awaiting an official patch from the vendor.
