Privilege escalation in mk_tsm agent plugin in Checkmk before 2.2.0p18, 2.1.0p38 and 2.0.0p39 allows local user to escalate privileges

Insufficient authentication flow in Checkmk before 2.2.0p18, 2.1.0p38 and 2.0.0p39 allows attacker to use locked credentials

Improper neutralization of active check command arguments in Checkmk < 2.1.0p32, < 2.0.0p38, < 2.2.0p4 leads to arbitrary command execution for authenticated users.

HTML Email Injection in Tribe29 Checkmk <=2.1.0p23; <=2.0.0p34, and all versions of Checkmk 1.6.0 allows an authenticated attacker to inject malicious HTML into Emails

Improper Input Validation of LDAP user IDs in Tribe29 Checkmk allows attackers that can control LDAP user IDs to manipulate files on the server. Checkmk <= 2.1.0p19, Checkmk <= 2.0.0p32, and all versions of Checkmk 1.6.0 (EOL) are affected.

The web management console of CheckMK Enterprise Edition (versions 1.5.0 to 2.0.0p9) does not properly sanitise the uploading of ".mkp" files, which are Extension Packages, making remote code execution possible. Successful exploitation requires access to the web management interface, either with valid credentials or with a hijacked session of a user with administrator role. NOTE: the vendor states that this is the intended behavior: admins are supposed to be able to execute code in this manner
