CVE-2024-50321
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 infinite loop in Ivanti Avalanche before 6.4.6 allows a remote unauthenticated attacker to cause a denial of service.
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 confidenceAn infinite loop vulnerability exists in Ivanti Avalanche versions prior to 6.4.6. A remote unauthenticated attacker can trigger this condition to cause a denial of service by causing the application to enter an infinite loop, likely through specially crafted input to a specific functionality.

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 Ivanti Avalanche is installedCheck for Ivanti Avalanche installation directories or installed programs list on the system. Common installation paths include C:\Program Files\Ivanti or C:\Ivanti. On Linux, check /opt/ivanti or similar locations.Affected if Ivanti Avalanche software is present on the system
-
Determine installed versionLocate the Avalanche version information, typically found in an About dialog within the application, a version file in the installation directory, or via the software's built-in version check feature.Affected if The installed version is lower than 6.4.6 (e.g., 6.4.5, 6.4.0, 6.3.x, etc.)
-
Confirm affected service is runningCheck if the Avalanche server service or Wavelink Avalanche service is actively running. Look for processes named AvalancheServer.exe, AvalancheService.exe, or similar in the task manager or running services list.Affected if The Avalanche server service is running and accepting connections
-
Assess network exposureDetermine if the Avalanche management console or server ports are accessible from untrusted networks. Check firewall rules, listening ports (commonly 80, 443, 8080, or 8443 for Avalanche), and network ACLs restricting access.Affected if The Avalanche service is accessible from untrusted network segments or the public internet
If Ivanti Avalanche is installed with a version below 6.4.6 and the service is network-accessible, the environment is affected by this infinite loop vulnerability.

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 · scoped6.4.6
Upgrade Ivanti Avalanche to version 6.4.6 or later to address the infinite loop vulnerability. As a defense-in-depth measure, restrict network exposure of the affected service to trusted users only.
6.4.6
- Check current Ivanti Avalanche version via administration console or command line
- Review upgrade documentation and release notes for 6.4.6
- Backup the current Avalanche configuration and database
- Download Ivanti Avalanche 6.4.6 or later from official Ivanti download portal
- Stop Avalanche services before upgrade
- Install the 6.4.6 version following standard upgrade procedures
- Start Avalanche services after upgrade completes
- Verify the application is running and accessible
