"According to its self-reported version, the MySQL Enterprise Monitor application running on the remote host is 
4.0.x prior to 4.0.13.5349 or 8.0.x prior to 8.0.21.1240. It is, therefore, affected by multiple vulnerabilities:
  - A buffer overflow condition exists in the Montgomery squaring procedure due to unsufficient validation
  of user-supplied input. An unauthenticated, remote attacker can exploit this, to cause a denial of service
  condition or the execution of arbitrary code. (CVE-2019-1551).

  - A denial of service (DoS) vulnerability exists in the SSL_check_chain() function due to a NULL pointer
  dereference. An unauthenticated, remote attacker can exploit this issue, to cause the application 
  to stop responding (CVE-2020-1967).

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