CVE-2025-59815

Authenticated command execution via legacy Billing interface

Published Sep 25, 2025 · Updated Sep 25, 2025

Command injection in Zenitel ICX-500 and ICX-510 before 1.4.3.3 allows remote authenticated users to execute system commands. The legacy Billing Administration interface passes attacker-controlled input into an operating-system command context without sufficient neutralization, although public records do not identify the handler or parameter. Administrative credentials and local-infrastructure access are required; successful exploitation grants shell access and control over device data and operation.
