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
There exists an insecure default user permission in Google Cloud Migrate to containers from version 1.1.0 to 1.2.2 Windows installs. A local "m2cuser" was greated with administrator privileges. This posed a security risk if the "analyze" or "generate" commands were interrupted or skipping the action to delete the local user “m2cuser”. We recommend upgrading to 1.2.3 or beyond

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

Google Cloud Migrate to containers (Windows versions 1.1.0-1.2.2) creates a local user account named 'm2cuser' with administrator privileges during its 'analyze' or 'generate' operations. If these commands are interrupted or skip the cleanup action, the high-privilege local user persists on the system, creating a local privilege escalation and persistence vector.

MitigationUpgrade Google Cloud Migrate to containers to version 1.2.3 or later, which addresses the insecure default user permission by properly cleaning up the m2cuser account.

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. Check if Google Migrate To Containers is installed
    Open Programs and Features (appwiz.cpl) or check C:\Program Files\Google\Migrate To Containers for the executable and version. Alternatively, run: dir 'C:\Program Files\Google\Migrate To Containers' /b
    Affected if The product is installed and version is >= 1.1.0 and < 1.2.3
  2. Verify m2cuser account exists on the system
    Open Computer Management > Local Users and Groups > Users, or run: net user m2cuser
    Affected if The m2cuser account exists on the system
  3. Check if m2cuser has administrator privileges
    Open Computer Management > Local Users and Groups > Groups > Administrators, or run: net localgroup Administrators | findstr m2cuser
    Affected if The m2cuser account is listed as a member of the Administrators group
  4. Review analyze or generate command execution history
    Check event logs, scheduled tasks, or migration logs for interrupted or failed 'm2c analyze' or 'm2c generate' operations that may have skipped cleanup
    Affected if There are records of analyze or generate commands that were interrupted or did not complete cleanup

You are affected if Google Migrate To Containers version 1.1.0 to 1.2.2 is installed AND the m2cuser account exists on the system with administrator privileges.
