CVE-2023-32564
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 unrestricted upload of file with dangerous type vulnerability exists in Avalanche versions 6.4.1 and below that could allow an attacker to achieve a remove 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 · high confidenceAn unrestricted file upload vulnerability in Avalanche versions 6.4.1 and below allows attackers to upload files with dangerous types (likely executable files) to the server, which can then be accessed and executed to achieve remote code execution.

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 Ivanti Avalanche installation versionLocate the installed Avalanche version through the administration console, About section, or version file in the installation directory. Common paths include the server management interface or installation logs.Affected if The installed version is 6.4.1 or lower (any version below 6.4.1)
-
Confirm file upload functionality is enabledAccess the Avalanche administration interface and locate the file upload or resource distribution feature used for deploying files to mobile devices. Verify if this module is active and accessible.Affected if The file upload/distribution module is enabled and accessible to users
-
Check server-side file type validation configurationExamine the server configuration files or upload settings to determine whether file type validation is implemented. Look for allowlist or denylist configurations that restrict permitted upload types.Affected if No server-side file type allowlist validation is configured, or validation relies solely on file extension without content inspection
-
Verify uploaded file storage locationInspect the server configuration to determine where uploaded files are stored. Check if upload directories are placed within the web root or outside of it.Affected if Uploaded files are stored within the web-accessible directory structure
-
Check script execution settings for upload directoriesReview web server configuration (IIS, Apache, or embedded server) for the upload directory. Verify if script execution permissions are disabled for this location.Affected if Script execution is permitted in directories where uploaded files are stored
You are affected if your Avalanche version is 6.4.1 or below AND the file upload feature is enabled with no server-side validation restricting executable file types.
Generated from the published advisory. Verify against your own configuration.
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 · scoped6.4.1
Restrict and validate file upload types using server-side allowlist validation, verify file content using magic bytes rather than extension, store uploaded files outside the web root, and disable script execution in upload directories.
Avalanche 6.4.1
- Obtain Avalanche version 6.4.1 or later from the official Ivanti download portal or support channels
- Review the official Ivanti Avalanche upgrade documentation and release notes
- Create a complete backup of the current Avalanche installation, database, and configuration
- Test the upgrade in a non-production environment first
- Apply the upgrade to production systems following Ivanti's documented upgrade procedure
- Verify the upgrade was successful by checking the version number and testing core functionality
- Monitor logs and system behavior to ensure the vulnerability is remediated
