Vulnerability details
The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on a targeted system.
The weakness exists due to insufficient validation of user-supplied input by the trapper command function. An attacker can submitt specially crafted packets from an active Zabbix proxy, inject arbitrary commands and execute arbitrary code on the targeted system.
Successful exploitation of the vulnerability results in arbitrary code execution.
Proof-of-concept code demonstrating an exploit of this vulnerability is publicly available.
