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
URL redirection to untrusted site ('Open Redirect') vulnerability in file access component in Synology DiskStation Manager (DSM) before 6.2.4-25556-8, 7.0.1-42218-7, 7.1.1-42962-7 and 7.2.1-69057-2 allows remote authenticated users to conduct phishing attacks 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

An open redirect vulnerability exists in the file access component of Synology DiskStation Manager (DSM). The vulnerability allows authenticated users to craft URLs that redirect users to arbitrary external sites, enabling phishing attacks. The issue affects DSM versions prior to 6.2.4-25556-8, 7.0.1-42218-7, 7.1.1-42962-7, and 7.2.1-69057-2.

MitigationApply the appropriate DSM security update for the installed major version (6.2.4-25556-8, 7.0.1-42218-7, 7.1.1-42962-7, or 7.2.1-69057-2) to address the open redirect in the file access component. Consider implementing additional URL validation or Content Security Policy headers as a defense-in-depth measure.

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 DSM is installed
    Access the web management interface on port 5000 or 5001, or check for DSM processes via command line (e.g., ps aux | grep -i synology)
    Affected if DSM web interface is accessible or Synology-related processes are running
  2. Identify the installed DSM version
    Log into DSM web interface and navigate to Control Panel > System > System Information, or run `cat /etc/VERSION` on the NAS command line
    Affected if The version number is lower than 7.2.1-69057-2 (or 6.2.4-25556-8, 7.0.1-42218-7, 7.1.1-42962-7 for older major versions)
  3. Verify file access component is enabled
    Check if File Station or similar file access module is installed and active via Control Panel > Application Portal > File Station, or list enabled packages via `synopkg list --enabled`
    Affected if File Station or file access functionality is installed and enabled on the system
  4. Check for open redirect behavior
    Inspect URLs generated by the file access component for the presence of redirect parameters (e.g., 'redirect=' or 'next=' query parameters); attempt a controlled test with a known safe URL to observe if external redirection occurs
    Affected if The application accepts and follows redirect parameters pointing to external domains without sufficient validation

A user is affected if they are running any DSM version below 7.2.1-69057-2 (or the corresponding patch versions for other major releases) AND the file access component is enabled and accessible to authenticated users.

Fixed in 7.2.1-69057-2
Interim mitigation

Apply the appropriate DSM security update for the installed major version (6.2.4-25556-8, 7.0.1-42218-7, 7.1.1-42962-7, or 7.2.1-69057-2) to address the open redirect in the file access component. Consider implementing additional URL validation or Content Security Policy headers as a defense-in-depth measure.

Recommended fix High confidence

DSM 7.2.1-69057-2 (or appropriate branch fix: 6.2.4-25556-8, 7.0.1-42218-7, 7.1.1-42962-7)

  1. Identify the current DSM version running on the Synology device via Control Panel > System > System Information
  2. Determine the appropriate upgrade path based on current version branch: for DSM 6.2.x upgrade to 6.2.4-25556-8 or later, for DSM 7.0.x upgrade to 7.0.1-42218-7 or later, for DSM 7.1.x upgrade to 7.1.1-42962-7 or later, for DSM 7.2.x upgrade to 7.2.1-69057-2 or later
  3. Back up critical data on the Synology device before performing the upgrade
  4. Apply the update via Control Panel > Update & Restore > DSM Update
  5. After reboot, verify the installed DSM version matches the target fixed release
Caveat Standard DSM upgrade risks apply - ensure backups exist before updating
