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 limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in webapi component in Synology DiskStation Manager (DSM) before 6.2.3-25423 allows remote authenticated users to delete arbitrary files via unspecified vectors.

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 confidence

This is a path traversal vulnerability in the webapi component of Synology DiskStation Manager (DSM). It allows remote authenticated users to escape the intended restricted directory and delete arbitrary files on the system by manipulating file paths in webapi requests.

MitigationUpgrade DSM to version 6.2.3-25423 or later to obtain the patched webapi component. Additionally, review user account permissions and restrict API access to only necessary authenticated 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. Check DSM version via web interface
    Log into the Synology DiskStation Manager web interface. The version is typically displayed on the Welcome page or in the Control Panel > System > Version section. Alternatively, use the command line: cat /etc/VERSION
    Affected if The installed version is 6.2 or higher but lower than 6.2.3-25423
  2. Verify webapi component is accessible
    Confirm the webapi is enabled by attempting to access the API endpoint. In DSM, the webapi is typically available at /webapi/query.cgi. If the system responds to requests at this endpoint, the component is active.
    Affected if The webapi endpoint responds to requests (component is enabled and reachable)
  3. Confirm remote authentication is enabled
    Check if the DSM allows remote user authentication. In Control Panel > User & Group, verify that user accounts exist and remote access is permitted. The vulnerability requires an authenticated user session.
    Affected if Remote authenticated users can log into DSM via the web interface or API
  4. Determine if the system is exposed to untrusted networks
    Review network firewall rules and VPN/access controls. Check if the DSM management interface (port 5000/5001) or webapi endpoints are accessible from untrusted networks or the internet.
    Affected if The webapi is accessible from networks outside the trusted internal environment

The system is affected if DSM version is 6.2 or higher but below 6.2.3-25423, the webapi component is accessible, and remote authenticated users can access the system.

Fixed in 6.2.3-25423
Interim mitigation

Upgrade DSM to version 6.2.3-25423 or later to obtain the patched webapi component. Additionally, review user account permissions and restrict API access to only necessary authenticated users.

Recommended fix High confidence

DSM 6.2.3-25423 or later

  1. Log into Synology DiskStation Manager (DSM) as an administrator
  2. Navigate to Control Panel > Update & Restore > DSM Update
  3. Check the current DSM version under Control Panel > About to confirm it is below 6.2.3-25423
  4. If available, apply the latest DSM update from Control Panel > Update & Restore to reach version 6.2.3-25423 or newer
  5. Alternatively, download the DSM 6.2.3-25423 (or newer) update file from Synology's Download Center and manually apply it via Control Panel > Update & Restore > Manual DSM Update
  6. After the update completes, verify the DSM version under Control Panel > About shows 6.2.3-25423 or later
  7. Confirm the webapi functionality is operating normally after the upgrade
Caveat Standard DSM upgrade risks apply - review release notes for any configuration or feature changes before upgrading production systems
