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 · unedited
Improper permissions in the installer for the Intel(R) Falcon 8+ UAS AscTec Thermal Viewer, all versions, may allow an authenticated user to potentially enable escalation of privilege via local access.

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 confidence

The installer for Intel Falcon 8+ UAS AscTec Thermal Viewer sets improper file system permissions, allowing an authenticated local user to modify executables, DLLs, or configuration files that subsequently run with elevated privileges, enabling local privilege escalation.

MitigationApply vendor-supplied updated installer that sets restrictive permissions (minimum required for Users/Administrators). If no update available, manually audit and harden permissions on installed files using ICACLS to remove unnecessary write access for standard users.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify if AscTec Thermal Viewer is installed
    Check for the installation directory at typical locations: C:\Program Files\Intel\Falcon 8+ UAS AscTec Thermal Viewer\ or C:\Program Files (x86)\Intel\Falcon 8+ UAS AscTec Thermal Viewer\. Also check the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for an entry named 'Intel Falcon 8+ UAS AscTec Thermal Viewer'.
    Affected if The software is present on the system.
  2. Identify the installation directory
    If found in the registry, read the InstallLocation value to determine the installation path. If the registry entry is missing, search the file system for folders containing 'AscTec' or 'ThermalViewer'.
    Affected if A directory containing AscTec Thermal Viewer files exists on the system.
  3. Check write permissions on executable files
    Open Command Prompt as a standard (non-admin) user and attempt to write to .exe files in the installation directory, or use ICACLS from an admin command prompt to list permissions: icacls 'C:\Program Files\Intel\Falcon 8+ UAS AscTec Thermal Viewer\*.exe'
    Affected if Standard users or the 'Users' group have write (F) or write (W) permissions on executable files in the installation directory.
  4. Check write permissions on DLL files
    Use ICACLS to examine permissions on .dll files: icacls 'C:\Program Files\Intel\Falcon 8+ UAS AscTec Thermal Viewer\*.dll'
    Affected if Standard users or the 'Users' group have write permissions on DLL files that may be loaded by elevated processes.
  5. Check write permissions on configuration files
    Use ICACLS on config files: icacls 'C:\Program Files\Intel\Falcon 8+ UAS AscTec Thermal Viewer\*.ini' and icacls 'C:\Program Files\Intel\Falcon 8+ UAS AscTec Thermal Viewer\*.xml' and icacls 'C:\Program Files\Intel\Falcon 8+ UAS AscTec Thermal Viewer\*.cfg'
    Affected if Standard users or the 'Users' group have write permissions on configuration files that are read by elevated processes.
  6. Verify if affected executables run with elevated privileges
    Examine the application manifest or test by launching the .exe files while monitoring the resulting process privileges using Task Manager or Process Explorer, looking for 'Run as administrator' indicators or higher integrity levels.
    Affected if The executables run with administrator-level privileges while residing in a directory writable by standard users.

A user is affected if the Intel Falcon 8+ UAS AscTec Thermal Viewer is installed and standard users have write access to executables, DLLs, or configuration files that run with elevated privileges.
