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
A command injection vulnerability was found in the web administration console in SoftNAS Cloud before 4.0.3. In particular, the snserv script did not sanitize the 'recentVersion' parameter from the snserv endpoint, allowing an unauthenticated attacker to execute arbitrary commands with root permissions.

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
How this class of weakness works · CWE-78

User input reaches a shell or system command without being fully separated from the command itself, so an attacker can append their own instructions. Because these run with the application's privileges, it often means full control of the host. The lasting fix is to avoid the shell entirely — call APIs directly and pass arguments as data, never as concatenated strings.

Upgrade available Upgrade to 4.0.3 or later
Fixed in 4.0.3
Recommended fix Moderate confidence

4.0.3

  1. 1. Back up the current SoftNAS Cloud configuration and data before proceeding with any upgrade.
  2. 2. Download SoftNAS Cloud version 4.0.3 or later from the official SoftNAS download portal (docs.softnas.com).
  3. 3. Review the official upgrade documentation for SoftNAS Cloud to ensure a proper upgrade path from your current version.
  4. 4. Apply the upgrade following the documented upgrade procedure for your deployment method (AWS, Azure, VMware, etc.).
  5. 5. Verify the upgrade was successful by logging into the web administration console and checking the version number.
  6. 6. Confirm the 'recentVersion' parameter in the snserv endpoint is now properly sanitized.
Caveat Review SoftNAS upgrade documentation for any version-specific migration requirements or configuration changes between your current version and 4.0.3
