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
Exposure of sensitive information to an unauthorized actor vulnerability in Web Server in Synology DiskStation Manager (DSM) before 7.0.1-42218-2 allows remote attackers to obtain sensitive information 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 · moderate confidence

This is an information disclosure vulnerability in the Web Server component of Synology DiskStation Manager (DSM). The flaw allows remote unauthenticated attackers to obtain sensitive information through unspecified vectors. The vulnerability exists in DSM versions prior to 7.0.1-42218-2.

MitigationUpdate Synology DSM to version 7.0.1-42218-2 or later to remediate this vulnerability. As a defense-in-depth measure, restrict network exposure of the DSM web interface to trusted networks or VPN access only.

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 DSM version
    Log into DSM web interface and navigate to Control Panel > System > Update & Restore, or run 'cat /etc/VERSION' via SSH to view the exact DSM version number
    Affected if Version is 6.2 up to but not including 6.2.4-25556-3, OR version is 7.0 up to but not including 7.0.1-42218-2
  2. Confirm build number
    Run 'cat /etc/VERSION' or check the DSM login page footer which displays both version and build number (e.g., 7.0.1-42218)
    Affected if Build number is lower than 42218 for DSM 7.0.1 line, or lower than 25556 for DSM 6.2.4 line
  3. Verify Web Server is enabled
    Log into DSM > Control Panel > Application Portal > Web Station, or check via CLI with 'cat /etc/webstation'
    Affected if Web Station or the built-in web server is enabled and running
  4. Assess network exposure of DSM interface
    Check router/firewall rules to determine if DSM web port (5000/5001 or 80/443) is exposed directly to the internet without VPN or IP restriction
    Affected if DSM web interface is accessible from untrusted networks without authentication barriers

User is affected if their DSM version falls within the 6.2 to <6.2.4-25556-3 or 7.0 to <7.0.1-42218-2 range AND the web server component is accessible, even if restricted locally.

Recommended fix High confidence

DSM 6.2.4-25556-3 (for 6.2.x) or DSM 7.0.1-42218-2 (for 7.0.x)

  1. 1. Log in to Synology DiskStation Manager (DSM) as an administrator.
  2. 2. Navigate to Control Panel > Update & Restore > DSM Update.
  3. 3. Click on 'Download Update' to check for available updates.
  4. 4. If using DSM 6.2.x, select version 6.2.4-25556-3 or later.
  5. 5. If using DSM 7.0.x, select version 7.0.1-42218-2 or later.
  6. 6. Confirm the update and allow the system to restart after installation.
  7. 7. Verify the DSM version matches or exceeds the fixed release after the update completes.
Caveat Standard DSM update risks apply - ensure backups exist and review release notes for any configuration or feature changes before updating
