CVE-2024-36081
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 · uneditedWestermo EDW-100 devices through 2024-05-03 allow an unauthenticated user to download a configuration file containing a cleartext password. NOTE: this is a serial-to-Ethernet converter that should not be placed at the edge of the network.
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 confidenceThe Westermo EDW-100 serial-to-Ethernet converter has an unauthenticated information disclosure vulnerability allowing any user to download the device configuration file, which contains passwords stored in cleartext. This gives attackers immediate access to credentials without any authentication or exploitation. The CVSS 9.8 score reflects the trivial exploitability and complete confidentiality impact.

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.
-
Confirm device is Westermo EDW-100Identify the device model through device labeling, web interface, or SNMP sysDescr queryAffected if The device is a Westermo EDW-100 serial-to-Ethernet converter
-
Assess network accessibilityDetermine if the device management interface is reachable from untrusted networks or directly from the internetAffected if Device is exposed without firewall or network segmentation
-
Test unauthenticated config downloadAttempt to access the device configuration download or backup function without providing any credentialsAffected if Configuration file can be retrieved without any authentication
-
Inspect config for cleartext passwordsOpen any retrieved configuration file and examine password fields or credential entriesAffected if Passwords or sensitive credentials are stored in plaintext within the configuration
The environment is affected if the device is a Westermo EDW-100 and its configuration file containing cleartext passwords can be downloaded by an unauthenticated user.
Generated from the published advisory. Verify against your own configuration.
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 dataIsolate the device behind a firewall with no direct external access, contact Westermo for firmware updates that address the cleartext password storage and unauthenticated configuration download, and immediately rotate any credentials that may have been exposed. Network segmentation is critical given the note that this device should not be at the network edge.
