Name of the Vulnerable Software and Affected Versions Juniper Advanced Threat Prevention versions prior to 5.0.4

Description The issue is related to the storage of a secret passphrase in clear text in the /var/log/syslog file. This could allow an authenticated local user to view sensitive information. The set mcm command is an example of a CLI input that is logged in clear text.

Recommendations For Juniper Advanced Threat Prevention versions prior to 5.0.4, update to version 5.0.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the /var/log/syslog file to minimize the risk of exploitation. Avoid using the set mcm command until the issue is resolved.
