CVE-2023-0452
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 · uneditedEconolite EOS versions prior to 3.2.23 use a weak hash algorithm for encrypting privileged user credentials. A configuration file that is accessible without authentication uses MD5 hashes for encrypting credentials, including those of 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 confidenceEconolite EOS versions prior to 3.2.23 use the weak MD5 hashing algorithm to encrypt privileged user credentials stored in a configuration file. The configuration file is accessible without authentication, allowing unauthenticated attackers to obtain credentials for administrator and technician accounts.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Econolite EOS versionLocate and examine the installed EOS version using the system's about page, command line version check, or configuration file header. Common methods include accessing the web interface admin panel or running 'eos-version' or similar diagnostic command if available.Affected if The installed version is below 3.2.23 (e.g., 3.2.0 through 3.2.22, or any version prior to 3.2.23)
-
Locate the credential configuration fileSearch for configuration files that store user credentials. Common locations include /config, /settings, or application data directories. Look for files named similarly to userdb, credentials, passwd, or users in the EOS configuration directory.Affected if A configuration file containing user accounts (administrator and technician) is found on the system
-
Verify file accessibilityAttempt to read the credential configuration file without providing authentication credentials. Check file permissions and confirm whether the file is served over the network without requiring login.Affected if The configuration file containing credentials is accessible without authentication (no login required to read it)
-
Examine credential hashing mechanismOpen the credential configuration file and examine how passwords are stored. Look for 32-character hexadecimal strings (characteristic of MD5 hashes) rather than longer hashes or salted formats.Affected if Stored passwords appear as 32-character MD5 hashes or use another weak hashing algorithm rather than modern salted hashing
The environment is affected if Econolite EOS version is prior to 3.2.23 AND the credential configuration file is accessible without authentication AND credentials are stored using weak MD5 hashing.

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.
dbcve · scopedUpgrade Econolite EOS to version 3.2.23 or later which implements stronger credential hashing. Immediately rotate all administrator and technician passwords after patching, and restrict network access to the configuration file.
Econolite EOS version 3.2.23
- Identify the current Econolite EOS version running on the device
- Download Econolite EOS version 3.2.23 or later from the official vendor (Econolite)
- Review vendor release notes for version 3.2.23 to understand any configuration or migration requirements
- Back up the current system configuration before proceeding with the upgrade
- Apply the upgrade to the Econolite EOS system following standard vendor upgrade procedures
- After upgrade, verify that the configuration file is no longer using MD5 hashes for credential storage
- Confirm that the system is running version 3.2.23 or later
