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 4.6.0.x, contain a Symbolic Link (Symlink) Following vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to information tampering.

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.x contains a symlink following vulnerability. A low-privileged local attacker can exploit this by creating or manipulating symbolic links to redirect file operations to unintended locations, resulting in unauthorized information tampering.

MitigationRestrict file system permissions to prevent low-privileged users from creating symlinks in vulnerable directories; implement strict validation of symlink targets before file operations; verify all file paths resolve to expected locations.

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. Identify installed Dell AppSync version
    Locate the Dell AppSync installation directory and check the version file or executable properties. Common locations include C:\Program Files\Dell\AppSync or /opt/dell/appsync. Look for a version manifest, about dialog, or use the product's CLI version command if available.
    Affected if The installed version is 4.6.0.0 through 4.6.0.2 (any version >= 4.6.0.0 but < 4.6.0.3)
  2. Verify low-privileged user access to AppSync directories
    Review file system permissions on the Dell AppSync installation directory and its data/log directories. Use icacls (Windows) or ls -la (Linux) to list permissions for non-admin or non-root users.
    Affected if Low-privileged users have write or create permissions in directories where AppSync performs file operations
  3. Check for symlink creation capability in AppSync paths
    Identify directories used by AppSync for temporary files, data processing, or configuration. Attempt to create a test symbolic link as a low-privileged user, or review ACLs to determine if users can create symlinks in those paths.
    Affected if Non-privileged users can create or manipulate symbolic links in directories that AppSync uses for file operations
  4. Inspect AppSync service account privileges
    Examine the service account under which Dell AppSync runs. Check if it runs with elevated privileges and whether it follows symlinks during file operations.
    Affected if The AppSync service runs with elevated privileges and performs file operations that could be redirected via user-controlled symlinks

You are affected if Dell AppSync version is 4.6.0.0 through 4.6.0.2 and low-privileged users can create or manipulate symbolic links in directories used by the application for file operations.

Upgrade available Upgrade to 4.6.0.3 or later
Fixed in 4.6.0.3
Interim mitigation

Restrict file system permissions to prevent low-privileged users from creating symlinks in vulnerable directories; implement strict validation of symlink targets before file operations; verify all file paths resolve to expected locations.

Recommended fix Moderate confidence

Dell AppSync version 4.6.0.3 or later

  1. Identify the current installed version of Dell AppSync
