    could exploit this vulnerability to view and modify sensitive information in the database of the affected
    application. (CVE-2022-34388)

  - Dell SupportAssist for Home PCs (version 3.11.4 and prior) and  SupportAssist for Business PCs (version
    3.2.0 and prior) contain a privilege escalation vulnerability. A local authenticated malicious user could
    potentially exploit this vulnerability to elevate privileges and gain total control of the system. (CVE-2022-34387)

  - SupportAssist for Home PCs (version 3.11.4 and prior) and  SupportAssist for Business PCs (version 3.2.0
    and prior) contain cryptographic weakness vulnerability. An authenticated non-admin user could potentially
    exploit the issue and obtain sensitive information. (CVE-2022-34386)

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