The version of Zoom VDI Meeting Client installed on the remote host is prior to 5.15.2. It is, therefore, affected by a vulnerability as referenced in the ZSB-23038 advisory.

  • Improper neutralization of special elements in Zoom Desktop Client for Windows and Zoom VDI Client before 5.15.2 may allow an unauthenticated user to enable an escalation of privilege via network access.
    (CVE-2023-39213)

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