itsourcecode Construction Management System Parameter borrowed_equip_report.php sql injection

Successful exploitation of CVE-2026-5620 allows an attacker to inject malicious SQL code into the application's database queries. This can lead to a range of consequences, including unauthorized access to sensitive data such as user credentials, financial records, and project details. Depending on the database permissions, an attacker might even be able to modify or delete data, potentially disrupting business operations. The remote nature of the vulnerability means an attacker doesn't need to be on the same network as the server to exploit it. This vulnerability shares similarities with other SQL injection attacks where attackers leverage user input to bypass security controls and gain unauthorized access.

Organizations utilizing itsourcecode Construction Management System versions 1.0.0–1.0, particularly those with publicly accessible instances, are at risk. Shared hosting environments where multiple users share the same database are especially vulnerable, as a compromise of one user's account could potentially expose data for other users.

• php: Examine web server access logs for requests to /borrowedequipreport.php with unusual or malformed parameters in the Home variable. Look for patterns indicative of SQL injection attempts (e.g., ' OR 1=1 --).

grep 'borrowed_equip_report.php.*Home=[^a-zA-Z0-9]' /var/log/apache2/access.log

The primary mitigation for CVE-2026-5620 is to upgrade to a patched version of itsourcecode Construction Management System as soon as it becomes available. Until then, implement temporary workarounds to reduce the risk. A Web Application Firewall (WAF) can be configured to filter out potentially malicious SQL injection attempts targeting the /borrowedequipreport.php endpoint. Input validation and sanitization on the Home parameter are crucial. Specifically, implement parameterized queries or prepared statements to prevent SQL injection. Review and restrict database user permissions to limit the impact of a successful attack. After upgrade, verify the fix by attempting to inject SQL code through the /borrowedequipreport.php file and confirming that the input is properly sanitized.
