CVE-2023-46260
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) 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 confidenceA memory corruption vulnerability exists in the Mobile Device Server where specially crafted data packets can trigger heap or stack corruption, leading to potential denial of service or arbitrary code execution. The flaw is network-exploitable without authentication, consistent with the CRITICAL CVSS score.

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.
-
Confirm Ivanti Avalanche is installedLocate the Ivanti Avalanche application on the system or check installed programs listAffected if Ivanti Avalanche is present on the system
-
Identify the installed version of Ivanti AvalancheAccess the application's about, help, or system information section to view the version numberAffected if The version number is lower than 6.4.2
-
Verify the Mobile Device Server component is runningCheck if the Mobile Device Server service or process is active on the network-exposed systemAffected if The Mobile Device Server component is enabled and running on a reachable network port
-
Confirm network accessibility of the serviceTest whether the Mobile Device Server port is accessible from untrusted network sourcesAffected if The service is exposed to network access without proper firewall restrictions
The system 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 available patches or updates from the Mobile Device Server vendor. If no patch exists, implement network segmentation and firewall rules to restrict untrusted sources from reaching the affected service.
Avalanche 6.4.2 or later
- Download Avalanche version 6.4.2 or later from the vendor's official download site (download.wavelink.com)
- Backup the current Avalanche configuration and database before performing the upgrade
- Stop the Avalanche Mobile Device Server service
- Install the updated Avalanche 6.4.2 or newer version following the vendor's installation documentation
- Start the Avalanche Mobile Device Server service
- Verify the server is running correctly and all services are operational
