CVE Alert: CVE-2025-9643 – itsourcecode – Apartment Management System

Risk verdict

High risk: remote, unauthenticated SQL injection with a publicly available exploit for itsourcecode Apartment Management System 1.0.

Why this matters

The flaw enables attackers to manipulate the txtGasBill parameter over the network, potentially reading or altering database contents without user interaction. For apartment-management data, this can translate into financial record tampering, disclosure of sensitive tenant data, and service disruption of the system.

Most likely attack path

No user interaction required and no privileges needed (network vector, PR:N). An attacker can trigger the vulnerability by supplying crafted input to /setting/utility_bill_setup.php, leading to SQL injection at the database level. With the scope not changing, impacts are confined to the application’s data and availability, but can still enable data exfiltration or modification and potential lateral moves within the DB layer.

Who is most exposed

Web-facing deployments of the itsourcecode Apartment Management System (v1.0), especially those on internet-accessible PHP stacks or shared hosting, are at highest risk.

Detection ideas

• Logs showing unusual requests to /setting/utility_bill_setup.php with suspicious txtGasBill values
• SQL error messages or database query anomalies from the affected script
• Repeated, automated requests or payloads resembling SQL injection patterns
• WAF alerts for generic SQLi payloads targeting PHP endpoints
• Abrupt changes in data-access or unexpected data alterations in related tables

Mitigation and prioritisation

• Apply vendor patch or upgrade to a fixed version; verify 1.0 remediation guidance
• If patching is not feasible, implement input validation and parameterised queries (prepared statements) in the affected file
• Add WAF rules to block common SQLi payloads and monitor for txtGasBill anomalies
• Restrict exposure: disable remote access to the vulnerable endpoint where feasible; segment the app and enforce least privilege DB access
• Enable comprehensive DB/app logging and set up active monitoring for exfiltration indicators
• Note: KEV presence or EPSS score are not provided; given a PoC and public exploit, treat as high-priority remediation (explicit “treat as priority 1” only if KEV/EPSS criteria are confirmed).
