Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Missing certificate validation in Devolutions Remote Desktop Manager on macOS, iOS, Android, Linux allows an attacker to intercept and modify encrypted communications via a man-in-the-middle attack. Versions affected are : Remote Desktop Manager macOS 2024.3.9.0 and earlier Remote Desktop Manager Linux 2024.3.2.5 and earlier Remote Desktop Manager Android 2024.3.3.7 and earlier Remote Desktop Manager iOS 2024.3.3.0 and earlier Remote Desktop Manager Powershell 2024.3.6.0 and earlier

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 · high confidence

Remote Desktop Manager fails to validate SSL/TLS certificates in its network connections on macOS, iOS, Android, and Linux platforms. This allows man-in-the-middle attackers to intercept, read, and modify encrypted traffic by presenting invalid or forged certificates, completely bypassing the security provided by encryption.

MitigationUpdate Remote Desktop Manager to versions newer than 2024.3.9.0 (macOS), 2024.3.2.5 (Linux), 2024.3.3.7 (Android), 2024.3.3.0 (iOS), and 2024.3.6.0 (PowerShell). Avoid using untrusted networks until patched.

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. Confirm Remote Desktop Manager installation
    Open the application or check your installed programs for Devolutions Remote Desktop Manager (or Remote Desktop Manager PowerShell)
    Affected if The application is installed on macOS, iOS, Android, or Linux
  2. Identify installed version
    Open Remote Desktop Manager, then navigate to Help > About (or equivalent version information menu) to view the exact version number
    Affected if Version cannot be determined or is below the affected ranges
  3. Compare version against affected ranges
    Check if your version is: for Windows - any version before 2024.3.2.9, 2024.3.4.0, 2024.3.4.2, or 2024.3.10.3; for PowerShell - any version before 2024.3.7. If your version falls into any of these ranges, you are affected
    Affected if Installed version matches one of the affected version ranges: < 2024.3.2.9 OR < 2024.3.4.0 OR < 2024.3.4.2 OR < 2024.3.10.3 (Windows), or < 2024.3.7 (PowerShell)
  4. Verify network connection usage
    Check if Remote Desktop Manager is configured to connect to remote servers, VPNs, or remote sessions over network connections (the SSL/TLS validation flaw applies to all network connections the application makes)
    Affected if The application makes network connections to remote servers

You are affected if Remote Desktop Manager (or its PowerShell module) is installed on macOS, iOS, Android, or Linux and the installed version falls within any of the affected version ranges.
