Sign in to read
Impact	The CVSS vector (AV:N/AC:L/PR:L) indicates a network-accessible vulnerability with low attack complexity but requiring authenticated access, resulting in a 6.3 Medium base score. However, multiple risk signals elevate practical concern: the CVSS Environmental Score includes E:P (Proof-of-Concept Exists), indicating publicly available exploit code; no KEV (CISA Known Exploited Vulnerability) designation is present, so active widespread exploitation has not been confirmed by government sources, though the public POC lowers the barrier to attack. The integrity and confidentiality impacts (I:L/C:L) are limited by authentication requirement, but the low attack complexity combined with public exploit code means any authenticated user can potentially pivot to extract or modify sensitive project and tool data. Organizations using this system should treat this as a real priority due to POC availability, even though it requires valid credentials and lacks active exploitation confirmation.
Exploit ScenarioDerived	An authenticated user of the Construction Management System could craft a malicious request to /borrowedtool.php with a specially crafted SQL injection payload in the code parameter. For example, submitting code=1' OR '1'='1 would allow the attacker to bypass intended query filters and extract data from multiple database tables, such as user credentials, project details, or financial information related to borrowed tools. Given that public exploit code exists on GitHub (as referenced), attackers do not need deep SQL injection expertise to execute the attack.

Monitor Track and reassess. Why: LOW severity (CVSS 0.1-3.9).

AnalysisAIv1 – Apr 07, 2026

SQL injection in itsourcecode Construction Management System 1.0 allows authenticated remote attackers to execute arbitrary SQL queries via the code parameter in /borrowedtool.php, potentially leading to unauthorized data access, modification, or deletion. The vulnerability has a CVSS score of 6.3 (Medium) with publicly available exploit code; exploitation requires valid user credentials but no user interaction.

RemediationAI

Apply the latest patched version of itsourcecode Construction Management System from the vendor (patch version not independently confirmed in available data; consult https://itsourcecode.com/ for the latest release). In the interim, implement input validation and parameterized SQL queries (prepared statements) for all user-supplied parameters in /borrowedtool.php, enforce principle of least privilege for database user accounts, and restrict database access to the application server only. Code review of the /borrowedtool.php file and similar entry points is recommended to identify and remediate additional SQL injection vectors.

Technical ContextAI · show details

The vulnerability is a classic SQL injection (CWE-89) in a PHP-based construction management application. The flaw exists in the /borrowedtool.php file where user-supplied input from the code parameter is not properly sanitized before being incorporated into SQL queries. The affected product is itsourcecode Construction Management System (CPE: cpe:2.3:a:itsourcecode:construction_management_system:*:*:*:*:*:*:*:*), which appears to be a web-based application for managing construction project resources, including borrowed tools. Without parameterized queries or input validation, attackers can inject malicious SQL syntax to modify query logic and access sensitive database records.
