Zabbix before 1.8.19rc1, 2.0 before 2.0.10rc1, and 2.2 before 2.2.1rc1 allows remote Zabbix servers and proxies to execute arbitrary commands via a newline in a flexible user parameter.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Zabbix before 1.8.19rc1, 2.0 before 2.0.10rc1, and 2.2 before 2.2.1rc1 allows remote Zabbix servers and
    proxies to execute arbitrary commands via a newline in a flexible user parameter. (CVE-2013-6824)

The remote host is affected by the vulnerability described in GLSA-201401-26 (Zabbix: Shell command injection)

    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.
