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
Plaintext storage of a password exists in CONPROSYS HMI System (CHS) versions prior to 3.5.3. Because account information of the database is saved in a local file in plaintext, a user who can access the PC where the affected product is installed can obtain the information. As a result, information in the database may be obtained and/or altered by the user.

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

CONPROSYS HMI System (CHS) versions prior to 3.5.3 store database account credentials in plaintext within a local configuration file on the system. Any local user with file system access to the affected PC can read this file and obtain the plaintext database credentials, potentially allowing unauthorized access to and manipulation of the database.

MitigationUpgrade to CHS version 3.5.3 or later to obtain the patched version. Additionally, restrict file system permissions on the configuration directory to limit local user access to sensitive configuration files containing credentials.

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 CONPROSYS HMI System installation
    Locate the Conprosys HMI System installation directory on the system, typically found under the program files or Contec installation folder.
    Affected if The product is not installed or the installation directory cannot be located.
  2. Identify installed CHS version
    Access the program information or about section within the CHS application, or check the version metadata of the installed executable files.
    Affected if The installed version is any version prior to 3.5.3.
  3. Locate configuration directory
    Navigate to the CHS configuration directory within the installation folder, which contains configuration files for system settings and database connections.
    Affected if The configuration directory does not exist or cannot be accessed.
  4. Find database configuration file
    Search for configuration files that store database connection parameters such as database name, username, and password.
    Affected if No database-related configuration file is found in the configuration directory.
  5. Inspect credentials for plaintext storage
    Open the database configuration file using a text editor or command to view its contents. Look for fields labeled password or similar that contain unmasked, plaintext credential strings.
    Affected if Database credentials are visible in plaintext within the configuration file, allowing any local user with file access to read them.

A user is affected if CONPROSYS HMI System is installed with a version prior to 3.5.3 and a database configuration file contains plaintext credentials accessible to local users.

Upgrade available Upgrade to 3.5.3 or later
Fixed in 3.5.3
Interim mitigation

Upgrade to CHS version 3.5.3 or later to obtain the patched version. Additionally, restrict file system permissions on the configuration directory to limit local user access to sensitive configuration files containing credentials.
