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 · unedited
D-Link DWL-1000AP Firmware 3.2.28 #483 Wireless LAN Access Point stores the administrative password in plaintext in the default Management Information Base (MIB), which allows remote attackers to gain administrative privileges.

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 confidence

The D-Link DWL-1000AP wireless access point with firmware version 3.2.28 stores the administrative password in plaintext within the default Management Information Base (MIB), enabling remote attackers to retrieve credentials and gain full administrative access to the device.

MitigationUpdate to a patched firmware version if available; otherwise, replace the device with a current model and ensure strong, hashed passwords are used for administrative interfaces.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm device model
    Identify if the target device is a D-Link DWL-1000AP wireless access point by checking the device label, web interface, or SNMP system description
    Affected if Device is not a D-Link DWL-1000AP, then not affected by this specific CVE
  2. Check firmware version
    Access the device web interface, command line, or SNMP to retrieve the firmware version and compare it against the affected version 3.2.28_483
    Affected if Firmware version is exactly 3.2.28_483, then device is affected
  3. Verify SNMP service status
    Determine if the SNMP service is enabled on the device, as the vulnerability involves the Management Information Base (MIB)
    Affected if SNMP is enabled and accessible, the plaintext password can be retrieved from the MIB
  4. Check SNMP community string configuration
    Review the SNMP community string settings to determine if default values are in use
    Affected if Default SNMP community strings (such as public/private) are still configured, the MIB is remotely accessible without authentication
  5. Confirm remote administrative access
    Determine if remote administrative access to the device web interface or management interface is enabled
    Affected if Remote administrative access is enabled, an attacker can retrieve the plaintext password from the MIB and gain full control

A user is affected if they have a D-Link DWL-1000AP running firmware version 3.2.28_483 with SNMP enabled and default community strings configured, allowing unauthenticated retrieval of the plaintext administrative password from the MIB.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update to a patched firmware version if available; otherwise, replace the device with a current model and ensure strong, hashed passwords are used for administrative interfaces.

Recommended fix High confidence
  1. This is a 2001 vulnerability affecting D-Link DWL-1000AP firmware 3.2.28_483, which is extremely old hardware (early 2000s).
  2. The vulnerability is in the firmware itself (plaintext password storage in MIB), and no patch or firmware upgrade is available for this legacy device.
  3. Replace the DWL-1000AP with a modern wireless access point that receives regular security updates.
  4. If immediate replacement is not possible, place the device behind a firewall with restricted access and disable remote management interfaces.
  5. Ensure the device is not exposed to untrusted networks.
Caveat This hardware is end-of-life (released ~2001) and no longer supported by D-Link; replacement is required
