  - CVE-2024-3291: When installing Nessus Agent to a directory outside of the default location on a
  Windows host, Nessus did not enforce secure permissions for sub-directories. This could allow for
  local privilege escalation if users had not secured the directories in the non-default
  installation location.

  - CVE-2024-3292: A race condition vulnerability exists where an authenticated, local attacker on
  a Windows Nessus Agent host could modify installation parameters at installation time, which
  could lead to the execution of arbitrary code on the Nessus host.");
