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 neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in webapi component in Synology DiskStation Manager (DSM) before 7.0.1-42218-3 allows remote authenticated users to execute arbitrary commands 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

OS command injection vulnerability in the webapi component of Synology DiskStation Manager (DSM) allows remote authenticated users to execute arbitrary operating system commands. The vulnerability exists in versions prior to 7.0.1-42218-3 and requires valid authentication credentials for exploitation.

MitigationApply Synology DSM security update 7.0.1-42218-3 or later to patch the command injection vulnerability. As a defense-in-depth measure, restrict webapi access to trusted networks and minimize the number of privileged user accounts.

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 Synology DSM is installed
    Identify whether the target system is running Synology DiskStation Manager. This is typically a Synology NAS device or a Synology DSM virtual machine.
    Affected if The system is not running Synology DSM, this CVE does not apply.
  2. Check the installed DSM version
    Locate the DSM version information in the system control panel, about page, or via the command line. Compare the version number against the affected ranges: 6.2 to 6.2.4-25556-5, or 7.0 to 7.0.1-42218-3.
    Affected if The installed DSM version falls within 6.2 to 6.2.4-25556-5 (exclusive of 6.2.4-25556-5) OR within 7.0 to 7.0.1-42218-3 (exclusive of 7.0.1-42218-3).
  3. Verify the webapi component is accessible
    Determine if the webapi interface is exposed and reachable on the network. This is typically accessible via HTTPS on port 5001 or port 5000 on the Synology device.
    Affected if The webapi is not exposed to the network, the attack surface is reduced but the vulnerability still exists in the software if the version is affected.
  4. Confirm remote authentication is possible
    Check whether local user accounts or directory service accounts can authenticate to DSM remotely. Review the control panel security settings and user account configurations.
    Affected if Valid authentication credentials exist for a user who can access the webapi, the vulnerability is exploitable.

The environment is affected if Synology DSM is running a version between 6.2 and 6.2.4-25556-5, or between 7.0 and 7.0.1-42218-3, and the webapi is accessible with valid user credentials.

Upgrade available Upgrade to 6.2.4-25556-5 / 7.0.1-42218-3 or later
Fixed in 6.2.4-25556-57.0.1-42218-3
Interim mitigation

Apply Synology DSM security update 7.0.1-42218-3 or later to patch the command injection vulnerability. As a defense-in-depth measure, restrict webapi access to trusted networks and minimize the number of privileged user accounts.

Recommended fix High confidence

DSM 6.2.4-25556-5 or DSM 7.0.1-42218-3 (depending on your major version branch)

  1. 1. Log in to Synology DiskStation Manager as an administrator.
  2. 2. Navigate to Control Panel > Update & Restore > DSM Update.
  3. 3. Check the current DSM version by looking at the top-right corner of the DSM interface or navigating to Control Panel > System > Info.
  4. 4. If running DSM 6.2 (any version before 6.2.4-25556-5), initiate update to version 6.2.4-25556-5 or later.
  5. 5. If running DSM 7.0 (any version before 7.0.1-42218-3), initiate update to version 7.0.1-42218-3 or later.
  6. 6. Allow the update to complete and restart the DSM system as prompted.
  7. 7. After reboot, verify the new DSM version is installed and the vulnerability is remediated.
Caveat Review Synology's release notes before upgrading; some updates may change functionality or require reconfiguration of specific packages.
