DescriptionCVE.org

A weakness has been identified in itsourcecode Construction Management System 1.0. Affected by this issue is some unknown functionality of the file /borrowed_tool_report.php. This manipulation of the argument Home causes sql injection. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks.

AnalysisAI

SQL injection in itsourcecode Construction Management System 1.0 via the Home parameter in /borrowed_tool_report.php allows authenticated remote attackers to execute arbitrary SQL queries with limited impact on confidentiality, integrity, and availability. The vulnerability has a public exploit and CVSS score of 5.3, making it a moderate-severity issue requiring authentication but presenting real exploitation risk given POC availability.

Technical ContextAI

The vulnerability is a SQL injection flaw (CWE-74: Improper Neutralization of Special Elements used in an Output) occurring in PHP-based web application code. The affected endpoint /borrowed_tool_report.php accepts user-supplied input via the Home parameter without proper parameterization or input sanitization, allowing attackers to manipulate SQL query construction. This is a classic PHP web application vulnerability pattern where dynamic query building fails to use prepared statements or proper escaping mechanisms, enabling injection of malicious SQL syntax into database queries.

RemediationAI

Upgrade itsourcecode Construction Management System to a patched version released after this vulnerability disclosure. Immediate mitigations include: (1) implement input validation and parameterized SQL queries (prepared statements) in /borrowed_tool_report.php to neutralize SQL injection attacks; (2) restrict access to the Construction Management System to trusted users only and enforce strong authentication; (3) apply a Web Application Firewall (WAF) rule set to detect and block SQL injection patterns in the Home parameter; (4) audit database access logs for suspicious SQL commands. Consult https://itsourcecode.com/ for official patch availability and deployment guidance.
