A flaw was found in the Nagios Core application, where it is vulnerable to Site-Wide Cross-Site Request Forgery (CSRF) in many functions, such as adding – deleting for hosts or servers. The vulnerability is due to insufficient CSRF protections for the web UI on an affected version. This flaw allows an attacker to persuade a user of the interface to follow a malicious link. A successful exploit allows the attacker to perform arbitrary actions with the privilege level of the affected user. The highest threat from this vulnerability is to confidentiality, integrity, as well a system availability.

Comment 3 Hardik Vyas 2021-01-06 03:57:06 UTC 
Statement:

Red Hat Gluster Storage (RHGS) 3.5 no longer support monitoring using Nagios. Red Hat Gluster Storage Web Administration is now the recommended monitoring tool for Red Hat Storage Gluster clusters, hence the nagios package provided by RHGS will not be fixed.
