The version of Zoom VDI Meeting Client installed on the remote host is prior to 5.16.10. It is, therefore, affected by a vulnerability as referenced in the ZSB-24008 advisory.

  • Improper input validation in Zoom Desktop Client for Windows, Zoom VDI Client for Windows, and Zoom Meeting SDK for Windows may allow an unauthenticated user to conduct an escalation of privilege via network access. (CVE-2024-24691)

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