NVD · unedited
Protection Mechanism Failure of Software Downgrade in Zoom Rooms for Windows before 6.6.0 may allow an unauthenticated user to conduct an escalation of privilege via local access.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is a protection mechanism failure vulnerability in Zoom Rooms for Windows versions prior to 6.6.0 that allows software downgrade. An unauthenticated local attacker can exploit this to run an older, potentially vulnerable version of the software, enabling privilege escalation on the affected system.

MitigationUpdate Zoom Rooms for Windows to version 6.6.0 or later to remediate this vulnerability. Organizations should also implement controls to prevent unauthorized software downgrade attempts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Zoom Rooms for Windows is installed
    Open Windows Settings > Apps > Apps & features, or check for 'Zoom Rooms' in the program files directory (typically C:\Program Files\Zoom Rooms or C:\Program Files (x86)\Zoom Rooms)
    Affected if Zoom Rooms for Windows is present on the system
  2. Determine the installed Zoom Rooms version
    Right-click the Zoom Rooms application icon, select Properties, and check the Details tab for the Version field. Alternatively, check the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{Zoom Rooms GUID} for the DisplayVersion value
    Affected if No version information is available or the application cannot be found
  3. Compare installed version against 6.6.0
    Compare the version found in the previous step to 6.6.0. Zoom Rooms versions follow a major.minor.patch format (e.g., 6.5.10, 6.0.5)
    Affected if Installed version is less than 6.6.0 (e.g., 6.5.0, 6.0.10, 5.x.x series)
  4. Check if downgrade protection mechanism can be bypassed
    Attempt to run an older Zoom Rooms installer or check if older executable versions exist in the installation directory. Inspect if the application allows loading or downgrading to previous versions without integrity verification prompts
    Affected if The software permits running or loading older versions without proper integrity checks, indicating the protection mechanism failure is present

The system is affected if Zoom Rooms for Windows is installed with a version lower than 6.6.0 and the software allows downgrade to older versions without proper integrity verification.
