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
Dell AppSync, version(s) 4.6.0, contain(s) an Incorrect Permission Assignment for Critical Resource vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of privileges.

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

Dell AppSync version 4.6.0 contains an Incorrect Permission Assignment vulnerability where critical resources (likely files, folders, or services) have overly permissive ACLs. A low-privileged local user can exploit this misconfiguration to gain elevated privileges, likely by modifying or replacing executable files, service configurations, or DLLs that run with higher privileges.

MitigationCorrect the Access Control List (ACL) permissions on critical resources used by Dell AppSync to restrict write access to only privileged administrators, or update to a patched version if available from Dell.

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. Confirm Dell AppSync is installed
    Check for Dell AppSync in the Windows installed programs list via Control Panel > Programs and Features, or run 'Get-WmiObject -Class Win32_Product | Where-Object {$_.Name -like "*AppSync*"}' in PowerShell
    Affected if Dell AppSync is found on the system
  2. Identify installed AppSync version
    Check the version in Programs and Features, or look in the AppSync installation directory (typically C:\Program Files\Dell\AppSync or similar) for version information in assembly files, or right-click the main executable and view Properties > Details
    Affected if The version is 4.6.0.0 through 4.6.999 (any version >= 4.6.0.0 and < 4.6.1.0)
  3. Locate AppSync installation directory
    Common paths include C:\Program Files\Dell\AppSync or C:\Program Files (x86)\Dell\AppSync; use 'dir /s /b C:\*AppSync*' to search if not found in typical locations
    Affected if Installation directory is found and version check confirms affected version
  4. Review ACL permissions on critical AppSync resources
    Right-click the AppSync installation folder, select Properties > Security tab; check that Users, Everyone, or low-privileged groups do not have Write or Modify permissions; use 'icacls "<path>"' in Command Prompt for detailed permission output
    Affected if Non-administrator users have Write, Modify, or Full Control permissions on executable files, configuration files, or service-related folders
  5. Check AppSync service configuration
    Open Services (services.msc), locate the Dell AppSync service, right-click > Properties; check the executable path and ensure low-privileged users cannot modify the service binary or its configuration
    Affected if Service executable or configuration is writable by standard users or low-privilege accounts

The system is affected if Dell AppSync version 4.6.0.0 through 4.6.0.x is installed AND non-administrator accounts have Write or Modify permissions on AppSync executables, configuration files, or service paths.
