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 vulnerability has been identified in SPPA-T3000 MS3000 Migration Server (All versions). An attacker with local access to the MS3000 Server and a low privileged user account could gain root privileges by manipulating specific files in the local file system. This vulnerability is independent from CVE-2019-18308. Please note that an attacker needs to have local access to the MS3000 in order to exploit this vulnerability. At the time of advisory publication no public exploitation of this security vulnerability was known.

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

Local privilege escalation vulnerability in SPPA-T3000 MS3000 Migration Server where a low-privileged user with local access can manipulate specific files in the local file system to gain root privileges. The vulnerability stems from insecure file permissions or improper authorization checks on file operations.

MitigationRestrict physical and console access to the MS3000 Migration Server; review and harden file permissions on sensitive system files to prevent unauthorized modification by low-privileged users.

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 if MS3000 Migration Server component is installed
    Locate the SPPA-T3000 installation directory and verify the presence of the MS3000 Migration Server component. Check for executable files or services related to 'MS3000' or 'Migration Server' in the installation path.
    Affected if The MS3000 Migration Server component is present on the system
  2. Check ownership of system configuration files
    List ownership details of configuration files in the MS3000 installation directory using 'ls -la' or equivalent file system audit tools. Focus on files in /etc, /opt, or application config directories.
    Affected if Critical configuration files are owned by root but writable by non-root users
  3. Verify file permissions on sensitive system files
    Review file permissions on files that control service execution, authentication, or system configuration. Look for files with world-writable permissions or group-writable permissions accessible to low-privileged users.
    Affected if Sensitive system files have permissive write permissions accessible to standard or low-privileged user accounts
  4. Audit modification access for executable directories
    Check if directories containing executables, scripts, or libraries used by the Migration Server allow modification by non-privileged users. Use file system audit to identify write access by non-admin accounts.
    Affected if Directories with service executables or scripts are writable by low-privileged users
  5. Review user access controls on the Migration Server
    Examine local user accounts and group memberships to determine if low-privileged users have console or local access. Identify which users can interact with the MS3000 Migration Server process.
    Affected if Low-privileged local users exist and have access to the server environment where Migration Server runs

A user is affected if the MS3000 Migration Server component is installed and low-privileged local users can modify files or configurations that control service execution or system behavior.
