CVE-2023-46804
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 · uneditedAn attacker sending specially crafted data packets to the Mobile Device Server can cause memory corruption which could result to a Denial of Service (DoS).
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 confidenceA memory corruption vulnerability exists in the Mobile Device Server where specially crafted data packets sent by an unauthenticated attacker can trigger memory corruption, leading to denial of service. The vulnerability is exploitable remotely via network packets without authentication.

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.
-
Identify if Ivanti Avalanche is installedCheck for Ivanti Avalanche installation directories, services, or applications on the system. Common locations include Program Files or the Windows service list.Affected if Ivanti Avalanche is present on the system
-
Determine the installed version of Ivanti AvalancheLocate the Avalanche version information, typically found in the application properties, an about dialog, or a version file within the installation directory. Compare the version number to the affected range (anything below 6.4.2).Affected if The installed version is lower than 6.4.2
-
Verify the Mobile Device Server component is runningCheck if the Mobile Device Server service or process is active. This may appear as a Windows service or a running process related to Avalanche's server components.Affected if The Mobile Device Server component is enabled and running
-
Assess network exposure of the Mobile Device ServerDetermine if the Mobile Device Server is listening on network ports and accessible from untrusted networks. Check firewall rules and network configuration to see if the service port is exposed to external or untrusted networks.Affected if The Mobile Device Server is accessible from network locations outside the trusted internal network
The environment is affected if Ivanti Avalanche is installed with a version lower than 6.4.2 and the Mobile Device Server component is running and network-accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped6.4.2
Apply vendor-provided patches for the Mobile Device Server product. Network segmentation and filtering can reduce attack surface until patching is feasible.
6.4.2 or later
- Obtain Avalanche version 6.4.2 or later from download.wavelink.com or the official Wavelink distribution channel
- Back up the current Avalanche configuration and database according to standard backup procedures
- Stop the Avalanche Mobile Device Server service
- Install the Avalanche 6.4.2 upgrade following the vendor's installation documentation
- Start the Avalanche Mobile Device Server service
- Verify the service is running normally and the Mobile Device Server is accessible
