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 backup function in ABB Telephone Gateway TG/S 3.2 and Busch-Jaeger 6186/11 Telefon-Gateway saves the current settings and configuration of the application, including credentials of existing user accounts and other configuration's credentials in plaintext.

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 backup function in ABB Telephone Gateway TG/S 3.2 and Busch-Jaeger 6186/11 Telefon-Gateway devices saves configuration settings and user account credentials in plaintext format. An attacker with access to these backup files can extract plaintext passwords and other authentication credentials, leading to unauthorized access to the device and connected systems.

MitigationRestrict access to backup files through proper access controls, implement encryption for stored credentials within the backup mechanism, and rotate any credentials that may have been exposed in plaintext backups.

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. Confirm device model and firmware version
    Identify if the device is an ABB Telephone Gateway TG/S 3.2 or Busch-Jaeger 6186/11 Telefon-Gateway. Check device labeling, web interface, or administrative console for exact model and firmware version.
    Affected if Device matches either ABB TG/S 3.2 or Busch-Jaeger 6186/11 model
  2. Locate backup files on the device
    Check the device administrative interface, FTP server, SMB share, or SD card slot for backup files. Look for common backup file extensions such as .bak, .cfg, .bin, .xml, or .tar.
    Affected if Backup files exist on the device or have been exported
  3. Extract and inspect backup file contents
    Open or decompress the backup file using standard archive tools. Search within the file contents for plaintext password strings, user account entries, or credential fields.
    Affected if Backup file contains readable plaintext passwords or authentication credentials

If the device is an ABB Telephone Gateway TG/S 3.2 or Busch-Jaeger 6186/11 and its backup files contain plaintext passwords or credentials, the environment is affected by CVE-2019-19105.
