Authenticated code execution via unsanitized smart.disk.get parameters
Published Dec 18, 2023 · Updated Nov 27, 2024
Improper input validation in Zabbix Agent 2 affected releases allows remote authenticated users to execute code via smart.disk.get. The item key passes its path and RAID parameters into a shell command without sanitization, so crafted values can inject additional shell syntax when the SMART plugin invokes smartctl. Access requires an Agent 2 endpoint configured to accept the item request and privileges sufficient to submit the item key; exploitation can execute commands with the agent service account's rights.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
