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
The Motorola ACE1000 RTU through 2022-05-02 has default credentials. It exposes an SSH interface on port 22/TCP. This interface is used for remote maintenance and for SFTP file-transfer operations that are part of engineering software functionality. Access to this interface is controlled by 5 preconfigured accounts (root, abuilder, acelogin, cappl, ace), all of which come with default credentials. Although the ACE1000 documentation mentions the root, abuilder and acelogin accounts and instructs users to change the default credentials, the cappl and ace accounts remain undocumented and thus are unlikely to have their credentials changed.

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

The Motorola ACE1000 RTU exposes an SSH service on port 22 with five preconfigured accounts (root, abuilder, acelogin, cappl, ace) using default credentials. The undocumented cappl and ace accounts likely retain factory defaults, enabling unauthenticated remote access for maintenance and SFTP file transfers.

MitigationImmediately change default passwords for all five accounts, prioritizing the undocumented cappl and ace accounts; disable SSH if not required, or implement key-based authentication and network access controls to limit exposure.

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 the device model
    Check the system banner, login prompt, or run a command like 'uname -a', 'cat /proc/cpuinfo', or check the web interface for device identification to confirm it is a Motorola ACE1000 RTU
    Affected if The device is not a Motorola ACE1000 RTU - this CVE only applies to that specific product
  2. Verify SSH service is running
    Check if port 22 is listening by running 'netstat -an | grep :22' or 'nmap -p 22 <target>' or 'ss -tlnp | grep :22'
    Affected if Port 22 is not open or SSH service is not running - the vulnerability requires SSH to be accessible
  3. Test default credentials on SSH
    Attempt SSH login using each of these accounts with their suspected default passwords: root, abuilder, acelogin, cappl, ace. Try common default passwords such as the username itself, 'motorola', 'admin', 'password', or leave blank. Use: ssh <account>@<target_ip>
    Affected if Any of the five accounts accepts a default factory password, indicating they have not been changed from defaults
  4. Verify undocumented accounts exist
    After successful SSH login with any account, check for the presence of 'cappl' and 'ace' users in /etc/passwd or by running 'id cappl' and 'id ace', or attempt to switch to these users with 'su - cappl' or 'su - ace'
    Affected if The undocumented 'cappl' and 'ace' accounts exist and can be accessed with default credentials

You are affected if you have a Motorola ACE1000 RTU with SSH enabled and any of the five preconfigured accounts (root, abuilder, acelogin, cappl, or ace) retain their factory default passwords.

Mitigation

Immediately change default passwords for all five accounts, prioritizing the undocumented cappl and ace accounts; disable SSH if not required, or implement key-based authentication and network access controls to limit exposure.
