CVE-2024-22061
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 · uneditedA Heap Overflow vulnerability in WLInfoRailService component of Ivanti Avalanche before 6.4.3 allows a remote unauthenticated attacker to execute arbitrary commands
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 · high confidenceA heap overflow vulnerability exists in the WLInfoRailService component of Ivanti Avalanche versions prior to 6.4.3. This memory corruption flaw allows a remote attacker without authentication to execute arbitrary commands on the affected system due to improper bounds checking when handling heap allocations.

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 installationLocate the Ivanti Avalanche application on the system or check installed programs. Common installation paths include C:\Program Files\Ivanti\Avalanche or check Windows Services for Avalanche-related services.Affected if Ivanti Avalanche is installed on the system
-
Identify installed versionCheck the version of Ivanti Avalanche. This can typically be found in the application directory, in the file properties of the main executable, or via the Windows installed programs list. Look for a version number in the format such as 6.x.x.x.Affected if The installed version is lower than 6.4.3.528 (for example, 6.4.2.x, 6.3.x, etc.)
-
Verify WLInfoRailService componentCheck if the WLInfoRailService component is present and running. This may be visible as a Windows service or as a running process related to Ivanti Avalanche. Review the service configuration or process list.Affected if WLInfoRailService is installed and running as a service or active process on the system
-
Check network exposureDetermine if the WLInfoRailService port or endpoint is accessible from the network. This typically involves reviewing firewall rules, listening ports, or network configuration related to Ivanti Avalanche.Affected if The WLInfoRailService component is exposed to untrusted network access or accessible externally
The system is affected if Ivanti Avalanche with a version prior to 6.4.3.528 is installed and the WLInfoRailService component is active and accessible.

dbcve · scoped6.4.3.528
Upgrade Ivanti Avalanche to version 6.4.3 or later to remediate this vulnerability. If immediate patching is not possible, consider network segmentation to restrict access to the WLInfoRailService component from untrusted networks.
Ivanti Avalanche 6.4.3.528 or later
- 1. Identify all Ivanti Avalanche installations in your environment
- 2. Check current version of each installation (look for WLInfoRailService component version)
- 3. Download Ivanti Avalanche version 6.4.3.528 or later from the official Ivanti portal or support site
- 4. Review Ivanti upgrade documentation and release notes for upgrade prerequisites
- 5. Create a full backup of the current Avalanche installation including database and configuration
- 6. Test the upgrade in a non-production environment first
- 7. Schedule a maintenance window for the production upgrade
- 8. Perform the upgrade following Ivanti's official upgrade procedures
