CVE-2024-27984
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 Path Traversal vulnerability in web component of Ivanti Avalanche before 6.4.3 allows a remote authenticated attacker to delete specific type of files and/or cause 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 confidenceA path traversal vulnerability in the web component of Ivanti Avalanche before version 6.4.3 allows a remote authenticated attacker to manipulate file paths using directory traversal sequences (e.g., ../../) to access or delete specific file types outside the intended directory, or cause denial of service through malformed requests.

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 installation directory or check for Avalanche services running on the systemAffected if Ivanti Avalanche is present on the system
-
Identify installed versionCheck the Avalanche application version through the admin console, the Windows Programs and Features list, or the application's About/Version informationAffected if The installed version is below 6.4.3.528
-
Verify web component is accessibleDetermine if the Avalanche web interface is enabled and accessible on the network. Check the web service configuration and firewall rulesAffected if The web component is exposed to network access
-
Assess authentication exposureReview whether the web component allows authentication from untrusted users or is accessible from untrusted networksAffected if Untrusted or unauthenticated users can access the Avalanche web interface
The environment is affected if Ivanti Avalanche version is below 6.4.3.528 and the web component is accessible to remote attackers

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 · scoped6.4.3.528
Upgrade Ivanti Avalanche to version 6.4.3 or later. If immediate patching is not feasible, implement network segmentation to restrict access to the web component to authenticated, trusted users only and monitor for suspicious path traversal patterns in requests.
6.4.3.528 or later
- Ensure you have a backup of your current Ivanti Avalanche installation and database
- Download Ivanti Avalanche version 6.4.3.528 or later from the official Ivanti download portal or through your licensed support channel
- Review the Ivanti Avalanche upgrade documentation for your current version
- Install the upgrade following the vendor's recommended upgrade procedure
- After installation, verify the web component is functioning correctly
- Confirm the version number matches or exceeds 6.4.3.528
