CVE-2025-1193
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 · uneditedImproper host validation in the certificate validation component in Devolutions Remote Desktop Manager on 2024.3.19 and earlier on Windows allows an attacker to intercept and modify encrypted communications via a man-in-the-middle attack by presenting a certificate for a different host.
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 confidenceImproper host validation in the certificate validation component allows an attacker to present a certificate for a different host, enabling man-in-the-middle attacks to intercept and modify encrypted communications.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Remote Desktop Manager is installedCheck if Devolutions Remote Desktop Manager exists on the system. Look for the application in Program Files or the user's application data folder.Affected if The application is present on the system
-
Determine installed version numberLocate the installed version of Devolutions Remote Desktop Manager. This is typically available in the application properties, about dialog, or installation directory.Affected if The version cannot be determined or is older than 2024.3.20.0
-
Compare version to affected rangeCompare the installed version against the affected range: any version below 2024.3.20.0 is vulnerable.Affected if Installed version is less than 2024.3.20.0 (for example, 2024.3.19.0, 2024.2.x, or earlier)
-
Identify if certificate-based connections are usedDetermine whether the Remote Desktop Manager is configured to use SSL/TLS or certificate-based remote connections (RDP, SSH, VNC, or other protocols with encryption).Affected if The application uses encrypted connections with certificate validation, as the vulnerability lies in the certificate validation component
If Devolutions Remote Desktop Manager is installed with a version below 2024.3.20.0 and uses certificate-based encrypted connections, the environment is affected by this improper host validation flaw.

- Download Remote Desktop Manager version 2024.3.20.0 or later from the official Devolutions website (devolutions.net)
- Run the installer and follow the standard installation prompts to upgrade the software
- Verify the installation completed successfully by checking the version number in the application
- Test that your remote connections work properly after the upgrade to confirm functionality
