"According to its self-reported version number, the SolarWinds Log and
Event Manager installed on the remote host is prior to version 6.3.1 Hotfix 3.
It is, therefore, affected by multiple vulnerabilities :

  - Due to the program setting insecure permissions for management 
  scripts, a remote attacker to execute commands with elevated, 
  root privileges.(CVE-2017-5198)

  - A flaw exists in the mgrconfig.pl file that may allow 
  an authenticated remote attacker to escape from the sandbox 
  and execute commands with elevated privileges (CVE-2017-5199)

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