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 Wyse Management Suite, versions prior to WMS 5.5 HF1, contain an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Remote 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 · moderate confidence

Dell Wyse Management Suite versions prior to 5.5 HF1 contain a path traversal vulnerability that allows attackers to access files outside the restricted directory through specially crafted directory traversal sequences in HTTP requests. Successful exploitation enables remote code execution by writing malicious files to sensitive system locations.

MitigationUpgrade to Dell Wyse Management Suite version 5.5 HF1 or later. If immediate patching is not possible, restrict network access to trusted users and implement web application firewall rules to block directory traversal patterns.

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 Wyse Management Suite version
    Access the Wyse Management Suite admin console and navigate to Settings > About, or check the version via the installer/registry on the host system
    Affected if The installed version is listed as below 5.5 or exactly version 5.5 (prior to HF1)
  2. Confirm web interface accessibility
    Verify that the Wyse Management Suite web portal is accessible from network locations
    Affected if The web interface is exposed externally or to untrusted networks without proper access controls
  3. Review web server access logs for traversal patterns
    Examine HTTP access logs (typically in the Wyse Management Suite logs directory) for requests containing sequences such as ../, ..\, or URL-encoded equivalents
    Affected if Logs contain directory traversal sequences targeting sensitive system paths outside the web root
  4. Check for unauthorized files in system directories
    Inspect known sensitive directories such as C:\Windows\System32 (Windows) or /etc, /opt (Linux) for newly created or modified files that were not authored by administrators
    Affected if Unexpected executable or script files exist in system directories without corresponding legitimate deployment records
  5. Identify suspicious process or service modifications
    Review running processes and scheduled tasks on the Wyse Management Suite server for unfamiliar executables or scripts that were added after the software installation
    Affected if Newly created processes, services, or scheduled tasks exist that correlate with potential post-exploitation activity

A defender is affected if their Dell Wyse Management Suite installation is version 5.5 or earlier, and the web interface is accessible to untrusted users or shows evidence of directory traversal requests or unauthorized file creation.

Upgrade available Upgrade to 5.5 or later
Fixed in 5.5
Interim mitigation

Upgrade to Dell Wyse Management Suite version 5.5 HF1 or later. If immediate patching is not possible, restrict network access to trusted users and implement web application firewall rules to block directory traversal patterns.

Recommended fix Moderate confidence

WMS 5.5 HF1

  1. 1. Back up the current Wyse Management Suite configuration and database before initiating any upgrade.
  2. 2. Download WMS 5.5 HF1 from the Dell support portal (www.dell.com) using your organization's account credentials.
  3. 3. Log in to the Wyse Management Suite admin console with administrator privileges.
  4. 4. Navigate to the System Settings or Administration section where software updates are managed.
  5. 5. Initiate the upgrade process by applying the WMS 5.5 HF1 update package.
  6. 6. Monitor the upgrade progress and verify the system restarts successfully.
  7. 7. After the upgrade completes, confirm the version by checking the Wyse Management Suite about or version information.
  8. 8. Verify that the path traversal vulnerability is resolved by reviewing the release notes or security advisory for WMS 5.5 HF1.
