CVE-2024-42329

Service crash via unchecked WebDriver error pointer

Published Nov 27, 2024 · Updated Nov 27, 2024

NULL pointer dereference in Zabbix Server 7.0.0 through 7.0.3rc1 allows local users to crash the server through a Browser item. webdriver_session_query can fail without initializing wd->error, while Browser-object callers dereference that pointer when handling the failed request. Exploitation requires local low-privileged access and an unexpected WebDriver failure, and the reported consequence is a service crash.
