Checkmk Werk 13897: Fix command injection vulnerability

by Maximilian Wirtz

ID: 13897 Title: Fix command injection vulnerability Component: Notifications Level: 2 Class: Security fix Version: 2.2.0i1 Previously to this Werk an attacker who could control certain notification variables such as <tt>NOTIFICATIONTYPE</tt> or <tt>HOSTNAME</tt> was able to inject commands to the fall-back mail command. The commands were then executed as site user. With this werk the variable <tt>MAIL_COMMAND</tt> is no longer available in notification scripts. You can reduce the risk of exploitation with disabling the listening of the notification spooler (the default is disabled) (CEE/CME only feature). All maintained versions (>=1.6) are subject to this vulnerability. It is likely that also previous versions were vulnerable. To detect possible exploitation <tt>var/log/mknotifyd.log</tt> and <tt>var/log/notify.log</tt> can be checked for special shell characters like <tt>&&</tt> and odd quoting.

Checkmk Werk 13847: local: Do not crash upon invalid metric names

by Moritz Kiemer

ID: 13847 Title: local: Do not crash upon invalid metric names Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 In Checkmk 1.6 and earlier the backend would silently sanitize metric names according to the nagios specification. As this is no longer done, the local check plugin crashed upon invalid metric names. As the metric names may be provided by third party components we no longer crash, but issue a warning instead. The measured value will still be shown, and provided levels will be applied.
