CVE-2001-0619
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 · uneditedThe Lucent Closed Network protocol can allow remote attackers to join Closed Network networks which they do not have access to. The 'Network Name' or SSID, which is used as a shared secret to join the network, is transmitted in the clear.
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 Lucent Closed Network protocol transmits the Network Name/SSID (which serves as a shared secret for network authentication) in plaintext, allowing remote attackers to intercept this credentials and gain unauthorized access to closed networks.

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 Lucent Orinoco hardware or drivers in useReview system hardware inventory, network adapter listings, or driver information for 'Lucent Orinoco', 'Orinoco', or 'Lucent Wireless' componentsAffected if Lucent Orinoco wireless hardware or associated drivers are present in the environment
-
Determine if Closed Network mode is enabledAccess the wireless client configuration utility or registry settings for the Orinoco adapter and check whether Closed Network mode (also called Closed System or SSID-based access control) is turned onAffected if Closed Network mode is enabled on the Lucent Orinoco adapter
-
Verify the SSID/Network Name configurationInspect the configured Network Name (SSID) value in the wireless client settings for the Orinoco device. This SSID serves as the shared secret for Closed Network authenticationAffected if A Network Name/SSID is configured for use with Closed Network mode - the plaintext transmission of this value during authentication is the vulnerability
-
Confirm the device operates in an environment using Closed Network authenticationReview network infrastructure or wireless controller configurations to determine if the access points or network devices the Orinoco client connects to are using Closed Network or similar SSID-based access control that relies on the SSID as a shared secretAffected if The Orinoco client is connecting to networks that require Closed Network authentication where the SSID is used as the shared credential
A user is affected if Lucent Orinoco hardware with Closed Network mode enabled is in use, as the SSID used as a shared secret is transmitted in plaintext during authentication.

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 dataReplace or upgrade the Lucent Closed Network implementation to use modern, encrypted protocols such as WPA2/WPA3 with strong authentication, or implement additional security layers (VPN, MAC filtering) as intermediate controls if legacy hardware constraints exist.
