Description
Invocation of the Jolokia special agent with the login password in the command line in Checkmk versions 2.5.0 before 2.5.0p16 allows a local user on the Checkmk server to read the Jolokia login password from the process list while the special agent is running. This affects both explicitly configured passwords and passwords from the password store.
