CVE-2025-0432
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 · uneditedEWON Flexy 202 transmits user credentials in clear text with no encryption when a user is added, or user credentials are changed via its webpage.
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 EWON Flexy 202 industrial router transmits user credentials in cleartext (unencrypted) when adding new users or modifying existing user credentials through its web-based administration interface. An attacker on the network path can intercept these credentials using packet capture or man-in-the-middle techniques.

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 the device model is EWON Flexy 202Access the device web interface or check the device label/sticker; log into the admin panel and locate the device information or status page to verify the model numberAffected if The device is not an EWON Flexy 202 router - this CVE applies specifically to that model
-
Identify if the web admin interface is accessible over HTTPAttempt to access the device admin interface using http://[device-ip] (port 80) from a network-connected host; check if the login page loads over unencrypted HTTPAffected if The admin interface loads over HTTP (port 80) - credentials entered here are transmitted in cleartext
-
Verify whether HTTPS is enforced for the admin interfaceCheck the device web server configuration or try accessing via https://[device-ip] (port 443); examine whether the interface redirects HTTP to HTTPS or requires SSL/TLSAffected if HTTPS is not required or enforced - the device allows unencrypted HTTP access for administrative functions
-
Check if the admin interface is reachable from an untrusted networkReview the device network configuration to determine if the web admin interface is bound to all interfaces (0.0.0.0) or only to trusted internal IPs; verify firewall rules allow HTTP/HTTPS access from outside trusted segmentsAffected if The admin interface is accessible from untrusted network segments without VPN protection - an attacker on the network path can intercept traffic
A user is affected if the EWON Flexy 202 web admin interface is accessible over unencrypted HTTP (port 80) from any network path where an attacker could capture traffic.

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 dataEnable HTTPS on the EWON Flexy 202 administrative interface and/or restrict administrative access to a VPN or trusted network segment to prevent credential interception.
