CVE Alert: CVE-2025-9420 – itsourcecode – Apartment Management System

Risk verdict

High risk: remote, unauthenticated SQL injection with a publicly available exploit against itsourcecode Apartment Management System 1.0; immediate attention required.

Why this matters

Attacker can compromise data and potentially influence ongoing operations without user interaction. With data confidentiality, integrity and availability impacts (even partial) and a publicly released exploit, a credible threat exists for rapid automated abuse, data theft, or service disruption in exposed deployments.

Most likely attack path

Remote attack via network access to /floor/addfloor.php, exploiting the hdnid parameter to inject SQL. No authentication or user interaction required, using an attacker-controlled payload to influence the database (PR:N, UI:N). Scope remains unchanged, so exploitation targets the local database rather than crossing into other components; if DB access is broad, there is potential lateral movement within the application’s data store.

Who is most exposed

Web deployments of the product, likely internet-facing or accessible from hosted environments. Small businesses or managed hosting setups using version 1.0 are especially at risk if proper input handling and network protections are not in place.

Detection ideas

• Unexpected SQL error messages or database errors in web server logs.
• Spike in requests to addfloor.php with suspicious hdnid values or patterns typical of SQLi attempts.
• Logs showing failed or unusual database queries from the web app.
• WAF alerts for SQL injection payloads targeting PHP parameters.
• Anomalous data changes recorded in audit logs.

Mitigation and prioritisation

• Apply vendor patch or upgrade to a non‑vulnerable version; if unavailable, implement robust input validation and use parameterised queries in addfloor.php.
• Disable or tightly restrict remote access to the admin areas; implement IP allowlisting and require authentication/ MFA where feasible.
• Implement WAF rules and database query monitoring; enable detailed application and database auditing.
• Code review of the affected module; replace string-concatenated SQL with prepared statements; remove debug information.
• Plan patch deployment during a maintenance window with backups. Data on KEV status or EPSS is not provided; if KEV true or EPSS ≥0.5, treat as priority 1.
