CVE-2024-22123Network attack vector

File corruption and disclosure via modem path

Published Aug 9, 2024 · Updated Nov 3, 2025

Improper file validation in affected Zabbix Server releases allows remote authenticated users to corrupt server-readable files. The SMS media type accepts an arbitrary Linux path as its GSM modem device, and zabbix_server opens that path as a serial device, writes AT commands into it, and returns a small uncontrolled content fragment to the interface. Administrative access to media-type configuration and an SMS send attempt are required; corruption and disclosure are limited to files accessible to the server process.
