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
Econolite EOS versions prior to 3.2.23 lack a password requirement for gaining “READONLY” access to log files and certain database and configuration files. One such file contains tables with MD5 hashes and usernames for all defined users in the control software, including administrators and technicians.

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

Econolite EOS versions prior to 3.2.23 allow unauthenticated READONLY access to log files and database/configuration files. One accessible file contains tables with MD5-hashed usernames and passwords for all system users, including administrators and technicians, enabling credential theft.

MitigationUpgrade to Econolite EOS version 3.2.23 or later which enforces password authentication for file access. If immediate upgrade is not possible, implement network segmentation and firewall controls to restrict unauthorized access to the system.

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 installed Econolite EOS version
    Access the system administration interface or check system files for the EOS version number. Common locations include the web UI header, system info page, or configuration files in the installation directory.
    Affected if Version is below 3.2.23 or the version cannot be determined (indicating it may be an older release)
  2. Test unauthenticated access to log directory
    Attempt to access log files via HTTP/HTTPS or direct file system access without providing credentials. Common paths include /logs, /var/log/eos, or similar log directories exposed by the web server.
    Affected if Log files are accessible without authentication
  3. Test unauthenticated access to configuration files
    Attempt to access configuration or database files without authentication. Common paths include config directories, .db or .sqlite files, XML configuration files, or backup files.
    Affected if Configuration or database files are accessible without authentication
  4. Search for credential storage files
    Look for files containing user tables with MD5-hashed passwords. Check for database files (such as userdb, users.sqlite, or similar), configuration backups, or any file that may store authentication credentials.
    Affected if Files containing username and password tables (even if hashed) are accessible without authentication

The environment is affected if Econolite EOS version is below 3.2.23 AND unauthenticated access to log files, configuration files, or credential tables is possible.

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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to Econolite EOS version 3.2.23 or later which enforces password authentication for file access. If immediate upgrade is not possible, implement network segmentation and firewall controls to restrict unauthorized access to the system.

Recommended fix High confidence

Econolite EOS version 3.2.23 or later

  1. 1. Identify the current Econolite EOS version by accessing the system administration interface or checking system documentation.
  2. 2. Obtain the EOS version 3.2.23 or later from the official Econolite vendor渠道 (contact Econolite support or visit their official support portal).
  3. 3. Follow Econolite's standard upgrade procedure to apply version 3.2.23 or newer to the affected system.
  4. 4. After upgrading, verify that authentication is now required for READONLY access to log files and configuration files.
  5. 5. Confirm that the sensitive file containing MD5 hashes and usernames is no longer accessible without proper authentication.
