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 affected TBox RTUs store hashed passwords using MD5 encryption, which is an insecure encryption algorithm.

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

TBox RTUs store user passwords using MD5 hashing, which is cryptographically weak and vulnerable to rainbow table attacks and collision attacks. An attacker with access to the password hashes could potentially recover plaintext passwords.

MitigationMigrate password storage to a modern password hashing algorithm such as bcrypt, scrypt, or Argon2 with appropriate work factors, and implement a secure password migration path for existing 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 the TBox device model
    Access the device management interface or check system information files (e.g., /proc/cpuinfo, device configuration files) to determine the exact model variant (Ms Cpu32, Ms Cpu32 S2, Lt2, Tg2, or Rm2)
    Affected if The model is one of the affected variants (Ms Cpu32, Ms Cpu32 S2, Lt2, Tg2, or Rm2)
  2. Check the installed firmware version
    Use the device's web interface, CLI, or check firmware version files (typically found in /version, /etc/version, or via 'show version' command) to obtain the exact firmware version number
    Affected if The firmware version falls within the range >= 1.46 and <= 1.50.598
  3. Locate password storage configuration
    Examine the device configuration files where user credentials are stored. These may be in files such as user.cfg, passwd, users.xml, or similar configuration files in the /config, /etc, or data partitions
    Affected if Password configuration files exist on the device
  4. Inspect password hash format
    Open the password storage file identified in the previous step and examine the format of stored password hashes. Look for 32-character hexadecimal strings (typical MD5 length)
    Affected if Stored passwords appear as 32-character hex strings characteristic of MD5 hashes
  5. Verify hashing algorithm used
    If possible, compare a known plaintext password against its stored hash using MD5 verification (e.g., use md5sum command or hashlib in Python). Also examine any system files or documentation that may indicate the hashing algorithm
    Affected if The stored hashes are confirmed to be MD5 digests of plaintext passwords

The environment is affected if the device is an Ovarro TBox model (Ms Cpu32, Ms Cpu32 S2, Lt2, Tg2, or Rm2) running firmware version 1.46 through 1.50.598 that stores user passwords as MD5 hashes.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 1.50.598
Interim mitigation

Migrate password storage to a modern password hashing algorithm such as bcrypt, scrypt, or Argon2 with appropriate work factors, and implement a secure password migration path for existing users.
