CVE-2022-30234
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 · uneditedA CWE-798: Use of Hard-coded Credentials vulnerability exists that could allow arbitrary code to be executed when root level access is obtained. Affected Products: Wiser Smart, EER21000 & EER21001 (V4.5 and prior)
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 · moderate confidenceA hard-coded credentials vulnerability (CWE-798) in Wiser Smart, EER21000 & EER21001 devices (V4.5 and prior) allows attackers with root level access to execute arbitrary code. The firmware contains embedded credentials that can be extracted and used for unauthorized access.

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 the device modelDetermine if the target device is a Schneider Electric Wiser Smart EER21000 or EER21001 by checking the device label, web interface, or SNMP informationAffected if The device is not an EER21000 or EER21001 model
-
Check the firmware versionAccess the device web interface, CLI, or firmware metadata to determine the installed firmware version numberAffected if The firmware version is 4.5 or lower
-
Inspect firmware for embedded credentialsExtract the firmware image (via firmware dump, TFTP backup, or firmware analysis) and search within the binary or extracted filesystem for hardcoded username/password strings, encrypted credential blobs, or known credential patternsAffected if Hardcoded credentials are found embedded in the firmware image or configuration files
-
Verify credential validityAttempt authentication using any extracted credentials against the device management interfaces (web, SSH, or telnet)Affected if The extracted credentials successfully authenticate to the device
You are affected if you have a Wiser Smart EER21000 or EER21001 device running firmware version 4.5 or lower that contains extractable hardcoded credentials.

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 dataUpgrade to a version beyond V4.5 which should remove the hardcoded credentials. If upgrade is not possible, implement network segmentation and monitor for unauthorized access using the hardcoded credentials.
