CVE-2024-36463Network attack vector

Authenticated service interruption via unsafe atob strings

Published Nov 26, 2024 · Updated Nov 26, 2024

Access-control failure in Zabbix JS allows remote authenticated users to interrupt an affected Zabbix server or proxy. Its atob implementation creates arbitrary-content strings that access internal object properties instead of preserving their private status. Reachability requires low-privileged network access to script execution, and Zabbix has not published whether interruption occurs by crash or hang.
