Zabbix: Shell command injection

Background

Zabbix is software for monitoring applications, networks, and servers.

Description

If a flexible user parameter is configured in Zabbix agent, including a newline in the parameters will execute newline section as a separate command even if UnsafeUserParameters are disabled.

Impact

A remote attacker could possibly execute arbitrary shell code with the privileges of the process.

Workaround

There is no known workaround at this time.

Resolution

All Zabbix 2.2 users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-analyzer/zabbix-2.2.0-r4"

All Zabbix 2.0 users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-analyzer/zabbix-2.0.9-r1"
