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
An attacker sending specially crafted data packets to the Mobile Device Server can cause memory corruption which could result to a Denial of Service (DoS) or code execution.

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 memory corruption vulnerability in a Mobile Device Server where an unauthenticated attacker can send specially crafted data packets to trigger memory corruption. This can lead to denial of service or potentially remote code execution.

MitigationApply vendor-provided patches immediately. If no patch exists, consider network segmentation to restrict access to the Mobile Device Server and implement input validation at network boundaries.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 if Ivanti Avalanche is installed
    Check installed programs or services on the system for 'Ivanti Avalanche' or 'Avalanche' entries. Look in Add/Remove Programs, Program Files directories, or the Windows Services list.
    Affected if Ivanti Avalanche software is present on the system
  2. Determine the installed version of Ivanti Avalanche
    Locate the Avalanche installation directory and check version information in the application's About dialog, version file, or executable properties. Common locations include C:\Program Files\Avalanche or C:\Program Files (x86)\Avalanche.
    Affected if The installed version cannot be determined or is displayed as a version lower than 6.4.2
  3. Confirm the Mobile Device Server component is enabled
    Check the Avalanche server configuration or services to determine if the Mobile Device Server component is running. This is typically listed in the Avalanche console under server components or as a separate Windows service.
    Affected if Mobile Device Server component is installed and active
  4. Compare installed version against affected range
    Document the exact version number found and compare it to the affected range: any version below 6.4.2 is vulnerable.
    Affected if The installed version is below 6.4.2 (for example, 6.4.0, 6.3.x, 6.2.x, etc.)

A system is affected if Ivanti Avalanche with a Mobile Device Server component is installed and the version is lower than 6.4.2.

Upgrade available Upgrade to 6.4.2 or later
Fixed in 6.4.2
Interim mitigation

Apply vendor-provided patches immediately. If no patch exists, consider network segmentation to restrict access to the Mobile Device Server and implement input validation at network boundaries.

Recommended fix High confidence

Avalanche 6.4.2 or later

  1. 1. Back up the current Avalanche configuration and database before upgrading.
  2. 2. Download the Avalanche 6.4.2 (or latest) installer from the official Wavelink download portal at download.wavelink.com.
  3. 3. Stop the Avalanche services (Mobile Device Server and related components).
  4. 4. Run the installer on the Avalanche server and follow the upgrade wizard prompts.
  5. 5. After installation completes, verify the new version is 6.4.2 or later.
  6. 6. Start the Avalanche services and verify normal operation.
  7. 7. Test Mobile Device Server functionality with device connections to confirm the vulnerability is remediated.
