Many vulnerabilities have been disclosed in Checkmk IT Infrastructure monitoring software that could be chained collectively by an unauthenticated, distant attacker to totally choose in excess of affected servers.

“These vulnerabilities can be chained collectively by an unauthenticated, distant attacker to acquire code execution on the server operating Checkmk variation 2.1.0p10 and lessen,” SonarSource researcher Stefan Schiller said in a specialized examination.

Checkmk’s open up resource edition of the checking resource is based on Nagios Main and offers integrations with NagVis for the visualization and generation of topological maps of infrastructures, servers, ports, and processes.
