The notification logic would wrongly assume that "always up" hosts may, in fact, be down and erroneously postpone notifications. This has been fixed, such hosts are never down.

[2.3.0] Checkmk Werk 16220 created: Change factory setting for "Lock user accounts after N logon failures"

by Checkmk werks level 1

Title: Change factory setting for "Lock user accounts after N logon failures" Class: feature Compatible: incomp Component: wato Date: 1700034155 Edition: cre Level: 1 Version: 2.3.0b1 The factory setting for the rule "Lock user accounts after N logon failures" changes from `unset` to `10`. If enabled local user accounts are locked after N failed login attempts. (LDAP connected users are not affected.) Previous to this Werk a newly created site set this value to `10` but when reset to the factory setting the option was disabled. If you disabled this setting via "Reset to default" this setthing is now set to `10` again.

[2.3.0] Checkmk Werk 14216 created: Prevent LDAP users from disappearing at remote sites

by Checkmk werks level 1

Title: Prevent LDAP users from disappearing at remote sites Class: fix Compatible: compat Component: multisite Date: 1699364878 Edition: cre Level: 1 Version: 2.3.0b1 If a remote site had ldap connectors specified, which where not available at the central site, the users on the remote site were regularly removed during activate changes. This error was not always clearly visible, as the ldap users were resynchronised immediately after activate changes. However, this introduced race conditions, such as users not known to the monitoring core or automatic logouts at the remote site.

[2.1.0] Checkmk Werk 16216 created: Resolve Runas section in Checkmk Linux agent

by Checkmk werks level 1

Title: Resolve Runas section in Checkmk Linux agent Class: fix Compatible: compat Component: checks Date: 1699515827 Edition: cre Knowledge: undoc Level: 1 State: unknown Version: 2.1.0p37 Prior to this werk, the Runas section of the Checkmk agent contained a wrong trailing slash which resulted in an error with the find command. As a direct consequence, some or potentially all Runas rules were inadvertently ignored, leading to the plugin, not intended for root, being executed with root privileges. This werk fixes this behaviour.

[2.1.0] Checkmk Werk 16219 created: Limit length of Hostname

by Checkmk werks level 1

Title: Limit length of Hostname Class: security Compatible: compat Component: wato Date: 1699601325 Edition: cre Knowledge: undoc Level: 1 State: unknown Version: 2.1.0p37 Prior to this Werk it was possible to create Hosts with arbitrary length. Since Checkmk stores information in files which paths contain the hostname these path could exceed the allowed length leading to various errors to an extend that rendered the usage of parts of the GUI useless. We found this vulnerability internally. Affected Versions: LI: 2.2.0 LI: 2.1.0 LI: 2.0.0 Vulnerability Management: We have rated the issue with a CVSS Score of 2.7 (Low) with the following CVSS vector: <tt>CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L</tt>. We assigned CVE-2023-23549 to this vulnerability. Changes: This Werk adds a maximum length of 253 characters for the hostname.
