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
Improper certificate validation when connecting to gateways in Devolutions Server 2025.3.2 and earlier allows attackers in MitM position to intercept traffic.

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

Devolutions Server 2025.3.2 and earlier has improper SSL/TLS certificate validation when connecting to gateways. This allows an attacker positioned as a man-in-the-middle (MitM) to intercept and potentially manipulate traffic between the client and gateway by presenting a fraudulent certificate that the application accepts due to insufficient validation checks.

MitigationUpdate Devolutions Server to a version later than 2025.3.2 which contains proper certificate validation. As a compensating control, ensure network segmentation and avoid untrusted networks to reduce MitM exposure until the patch is applied.

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. Identify installed Devolutions Server version
    Check the installed version through the Devolutions Server administration console, installed programs list, or by querying the application directly via its version information feature
    Affected if The version displayed is before 2025.2.15.0, or is 2025.3.2.0 through 2025.3.2.x (any version >= 2025.3.2.0 but < 2025.3.3.0)
  2. Determine if gateway connections are configured
    Review the Devolutions Server configuration for any configured gateway connections or remote connection profiles that utilize gateway relay functionality
    Affected if Gateway connections are active or configured in the Devolutions Server environment
  3. Verify SSL/TLS certificate validation behavior
    Attempt a gateway connection while monitoring with a network proxy or SSL/TLS inspection tool to observe whether the application accepts certificates that would fail proper validation (such as self-signed or expired certificates)
    Affected if The connection succeeds with certificates that should be rejected under proper validation standards

The environment is affected if Devolutions Server version is before 2025.2.15.0 or between 2025.3.2.0 and 2025.3.2.x, and gateway connections are being used, allowing potential MitM interception of traffic.

Upgrade available Upgrade to 2025.2.15.0 / 2025.3.3.0 or later
Fixed in 2025.2.15.02025.3.3.0
Interim mitigation

Update Devolutions Server to a version later than 2025.3.2 which contains proper certificate validation. As a compensating control, ensure network segmentation and avoid untrusted networks to reduce MitM exposure until the patch is applied.

Recommended fix High confidence

2025.3.3.0 or later

  1. Back up the current Devolutions Server configuration and data
  2. Stop the Devolutions Server service
  3. Download version 2025.3.3.0 or later from the official Devolutions website
  4. Install the updated version following the vendor's upgrade documentation
  5. Restart the Devolutions Server service
  6. Verify the server is running and certificate validation is working correctly
