The version of Zoom Client for Meetings installed on the remote host is prior to 5.16.5. It is, therefore, affected by a vulnerability as referenced in the ZSB-23059 advisory.

  • Path traversal in Zoom Desktop Client for Windows, Zoom VDI Client for Windows, and Zoom SDKs for Windows may allow an authenticated user to conduct an escalation of privilege via network access. (CVE-2023-43586)

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