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 · uneditedImproper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in task management component in Synology DiskStation Manager (DSM) before 6.2.4-25553 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 confidenceOS command injection vulnerability in the task management component of Synology DiskStation Manager allows remote authenticated users to execute arbitrary operating system commands due to improper neutralization of special elements in user-supplied input.

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 checksWork through these to decide whether this CVE applies to you.
-
Check DSM versionLog into DSM and go to Control Panel > System > System Information, or run `cat /etc/VERSION` via SSH to retrieve the exact DSM build numberAffected if The installed version is lower than 6.2.4-25553 (build number below 25553)
-
Confirm remote access is enabledIn DSM Control Panel > Network > Network Settings, verify if remote access features such as QuickConnect or external network access are enabledAffected if Remote network access to the DSM interface is permitted, allowing external attackers to reach the login page
-
Verify authentication methodsGo to Control Panel > User & Group to confirm that user accounts exist and can log into the DSM web interfaceAffected if Any authenticated user account exists in DSM, as the vulnerability affects remote authenticated users
-
Check task manager accessibilityIn DSM, navigate to the Task Scheduler (Control Panel > Task Scheduler) to confirm the task management component is accessibleAffected if The Task Scheduler feature is available and enabled in the DSM installation
You are affected if your DSM version is below 6.2.4-25553 and the DSM interface is accessible to remote authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
