CVE-2025-59816

Authenticated database disclosure via Billing search SQL injection

Published Sep 25, 2025 · Updated Sep 25, 2025

SQL injection in Zenitel ICX-500 and ICX-510 before 1.4.3.3 allows remote authenticated users to read Billing Admin database data. The Billing Admin search field accepts UNION-based SQL input without neutralizing SQL control elements before a database query. Access requires a low-privilege account from an adjacent network; successful queries expose database records, including plaintext passwords.
