CVE-2026-5620 Overview
A SQL injection vulnerability has been discovered in itsourcecode Construction Management System version 1.0. The vulnerability exists in an unknown function within the file /borrowed_equip_report.php of the Parameter Handler component. Manipulation of the Home argument allows an attacker to perform SQL injection attacks. The vulnerability can be exploited remotely, and exploit information has been publicly disclosed.
Critical Impact
Remote attackers with low privileges can exploit this SQL injection vulnerability to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion of sensitive construction project information.

Technical Details for CVE-2026-5620
Vulnerability Analysis
This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the Construction Management System's equipment reporting functionality. The vulnerability arises from insufficient input validation in the Home parameter within the /borrowed_equip_report.php endpoint.
The Parameter Handler component fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows authenticated attackers to inject malicious SQL statements that are executed by the database backend. The attack can be initiated remotely over the network without requiring user interaction.
Since the exploit has been publicly disclosed, organizations using this software should prioritize remediation efforts to prevent potential data breaches or unauthorized access to construction project data.
Root Cause
The root cause of this vulnerability is improper input validation and lack of parameterized queries in the /borrowed_equip_report.php file. The Home parameter is directly concatenated into SQL queries without proper sanitization or use of prepared statements, enabling SQL injection attacks.
Attack Vector
The attack vector is network-based and requires low-level privileges to exploit. An authenticated attacker can craft malicious requests to the /borrowed_equip_report.php endpoint, manipulating the Home parameter to inject arbitrary SQL commands. The vulnerability does not require user interaction and can be exploited directly through HTTP requests.
The attack involves sending crafted HTTP requests containing SQL injection payloads in the Home parameter. Successful exploitation could allow attackers to bypass authentication, extract sensitive data, modify or delete database records, and potentially escalate privileges within the application.
Detection Methods for CVE-2026-5620
Indicators of Compromise
- Unusual SQL error messages in application or web server logs originating from /borrowed_equip_report.php
- HTTP requests containing SQL syntax characters (e.g., single quotes, UNION statements, OR 1=1 patterns) in the Home parameter
- Unexpected database query patterns or unauthorized data access attempts
- Anomalous network traffic to the affected endpoint from external sources
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect SQL injection patterns targeting the Home parameter
- Configure intrusion detection systems (IDS) to alert on SQL injection signatures in HTTP traffic
- Enable detailed logging for the /borrowed_equip_report.php endpoint and monitor for injection attempts
- Deploy SentinelOne Singularity Platform to detect and respond to exploitation attempts in real-time
Monitoring Recommendations
- Review web server access logs for requests to /borrowed_equip_report.php with suspicious query parameters
- Monitor database logs for unusual query patterns or unauthorized SELECT/INSERT/UPDATE/DELETE operations
- Set up alerts for multiple failed authentication attempts following SQL injection patterns
- Implement real-time monitoring of application behavior using endpoint detection and response (EDR) solutions
How to Mitigate CVE-2026-5620
Immediate Actions Required
- Restrict network access to the Construction Management System to trusted IP addresses only
- Implement input validation and sanitization for the Home parameter in /borrowed_equip_report.php
- Deploy a Web Application Firewall (WAF) with SQL injection detection rules
- Audit database permissions and apply the principle of least privilege
Patch Information
No official vendor patch is currently available for this vulnerability. Organizations should contact IT Source Code for remediation guidance. In the interim, implement the workarounds and defensive measures outlined below.
Additional technical details and vulnerability submissions can be found at:
Workarounds
