Detailsinfo

A vulnerability classified as critical has been found in Zabbix Agent 2 smartctl Plugin up to 5.0.46. Affected is some unknown functionality of the file smart.disk.get of the component Parameter Handler. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Zabbix Agent 2 smartctl plugin does not properly sanitize smart.disk.get parameters, allowing an attacker to inject unexpected arguments into the smartctl command. In Zabbix 5.0 this allows for remote code execution.
