CVE Alert: CVE-2025-12617 – itsourcecode – Billing System

Risk verdict

High risk: a remote, unauthenticated SQL injection with a publicly available exploit enables rapid weaponisation against exposed billing systems.

Why this matters

Compromised data from customers and payments, tampering with invoices, or service disruption could result in financial loss, regulatory exposure, and reputational damage. Attackers may exfiltrate or alter sensitive records with little to no user interaction, increasing the window for exploitation.

Most likely attack path

No authentication is required to reach the vulnerable login endpoint, enabling an attacker to inject via the Password parameter and access the backend database. Post-exploit, data exfiltration, credential discovery, or table dumping are plausible, with possible lateral movement limited by database permissions but not prevented by the initial access.

Who is most exposed

Web-facing deployments of itsourcecode Billing System 1.0 are the primary risk, typical in SMBs or hosted environments where the admin login page is internet-accessible.

Detection ideas

• Unusual or large SQL error messages in web/app logs targeting login_crud.php
• Sudden spikes in failed password attempts or unusual query patterns to the login endpoint
• Anomalous database queries showing UNION/SELECT patterns in access logs
• WAF alerts for SQLi-like payloads to /admin/app/login_crud.php
• Unexpected data dumps or export activity from the billing DB

Mitigation and prioritisation

• Patch: apply vendor fix for the affected version as soon as available.
• Mitigations: enable parameterised queries, input validation, and strict least-privilege DB access; disable remote admin where feasible.
• network controls: restrict access to the login page by IP or VPN; implement WAF rules for SQLi signatures.
• monitoring: elevate logging of login_crud.php and alert on anomalous DB queries or data access.
• change management: rotate credentials for DB and admin accounts; verify data integrity after remediation.
• If KEV true or EPSS ≥ 0.5, treat as priority 1.
