The REMOTE environment variable was not set correctly in previous 1.5 releases.

Check_MK Werk 6173: Fixed possible crash in Check_MK and Check_MK HW/SW Inventory

by Lars Michelsen

ID: 6173 Title: Fixed possible crash in Check_MK and Check_MK HW/SW Inventory Component: Core & setup Level: 1 Class: Bug fix Version: 1.6.0i1 When using pretty outdated "Do hardware/software Inventory" rules which have been saved before 1.4, this could lead to crashing Check_MK and Check_MK HW/SW inventory services with errors like this: 'NoneType' object has no attribute 'get' Workaround: Open this ruleset and save the rules in the relevant folders. The configs will then be transformed and rewritten in the current format which prevents this crash.

Check_MK Werk 6107: Agent bakery signing key passphrases could be visible in access logs

by Lars Michelsen

ID: 6107 Title: Agent bakery signing key passphrases could be visible in access logs Component: WATO Level: 2 Class: Security fix Version: 1.6.0i1 When you are using the agent bakery for creating and distributing your monitoring agents it is likely that this change is relevant for you. In some parts of the GUI, after entering the passphrase of the agent signing keys, it could happen that the signing key passphrase you enter is written to the apache access log of your Check_MK server. As a result it may be visible in clear text to local system users (e.g. users with access to the command line) which scan the logs for it. This affects the access log of the system apache (normally located at /var/log/apache2) and the access log (/omd/sites/[site]/var/log/apache/*) of the sites apache (master site in distributed setups). You may want to scan the log files for the string "key_p_passphrase" to check whether or not you are affected. It can be done e.g. with: zgrep key_p_passphrase /var/log/apache2/access* /omd/sites/*/var/log/apache/access* In case you find something, you should clean it up. Delete the file or remove the secrets from that file. Even when it seems unlikely that your key has been compromised, it is recommended to stop using this signing key. Create a new key and proceed with this one.

Check_MK Werk 6189: OpenHardwareMonitorCLI did not run on some Win7 machines

by Jukka Aro

ID: 6189 Title: OpenHardwareMonitorCLI did not run on some Win7 machines Component: Checks & agents Level: 1 Class: Bug fix Version: 1.6.0i1 OpenHardwareMonitorCLI, the executable wrapper for triggering OpenHardwareMonitor by Check_MK Windows Agent, did not run on some Win7 machines. Moreover, it was not possible to compile OpenHardwareMonitorCLI with versions 4.x of Mono (tried with Mono 4.6.2.0 / XBuild 14.0). Providing the build option /p:TargetFrameworkVersion="v4.5" both fixed the build with Mono 4.x and made resulting executable compatible with all tested Windows versions (tested on Win7 and Server 2016).
