"According to the self-reported version of Nagios XI, the remote host is affected by multiple vulnerabilities, including
the following:

  - A path traversal vulnerability exists in Nagios XI below version 5.8.5 AutoDiscovery component and could lead to post 
    authenticated RCE under security context of the user running Nagios. (CVE-2021-37343)

  - Nagios XI before version 5.8.5 is vulnerable to local privilege escalation because xi-sys.cfg is being imported from 
    the var directory for some scripts with elevated permissions. (CVE-2021-37345)

  - Nagios XI before version 5.8.5 is vulnerable to SQL injection vulnerability in Bulk Modifications Tool due to improper 
    input sanitisation. (CVE-2021-37350)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
