NVD · unedited
D-Link DAP-1325 CGI Missing Authentication Information Disclosure Vulnerability. This vulnerability allows network-adjacent attackers to access various functionality on affected installations of D-Link DAP-1325 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the CGI interface. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-18804.

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

This is a missing authentication vulnerability in the CGI interface of D-Link DAP-1325 routers. Network-adjacent attackers can access the CGI interface without any credentials, allowing them to retrieve stored credentials (including administrative passwords) from the device configuration. The lack of authentication checks before sensitive functionality enables direct credential disclosure leading to full device compromise.

MitigationApply vendor firmware updates when available. Until patched, restrict network access to the router's management interface using firewall rules or network segmentation to prevent untrusted devices from reaching the CGI endpoints.

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. Identify the device model
    Access the router's web management interface or check the device label to confirm it is a D-Link DAP-1325 model
    Affected if Device is not a D-Link DAP-1325
  2. Check the installed firmware version
    Log into the router web interface and navigate to the Status or Management page to view the firmware version, or use the router's web API endpoint that exposes version information
    Affected if Firmware version is less than 1.09b03
  3. Verify CGI interface accessibility
    Attempt to access the router's CGI scripts directly over the network using a web browser or curl command (for example, accessing common CGI endpoints like /cgi-bin/ or similar endpoints that return device configuration) without providing any authentication credentials
    Affected if CGI interface returns configuration data or accepts commands without requiring any login credentials
  4. Check for credential exposure in responses
    Inspect any responses from the CGI interface for sensitive data such as stored usernames, passwords, or configuration parameters that should require authentication
    Affected if The CGI response contains plaintext credentials or sensitive configuration data without prior authentication

A user is affected if they have a D-Link DAP-1325 router running firmware version prior to 1.09b03 and the router's CGI interface is accessible on the network without requiring authentication credentials.

Upgrade available Upgrade to 1.09b03 or later
Fixed in 1.09b03
Interim mitigation

Apply vendor firmware updates when available. Until patched, restrict network access to the router's management interface using firewall rules or network segmentation to prevent untrusted devices from reaching the CGI endpoints.

Recommended fix Moderate confidence

D-Link DAP-1325 Firmware version 1.09b03 or later

  1. 1. Identify the current firmware version of the D-Link DAP-1325 device by accessing the router's web management interface.
  2. 2. Navigate to the firmware upgrade or administration section in the web UI.
  3. 3. Download the firmware version 1.09b03 or later from the official D-Link support website (support.dlink.com).
  4. 4. Upload the new firmware file through the web management interface and allow the device to complete the update process.
  5. 5. After the router restarts, verify the firmware has been updated to version 1.09b03 or newer.
  6. 6. Confirm the vulnerability is addressed by attempting to access CGI endpoints without authentication (or use vulnerability scanning tools if available).
Caveat firmware upgrades on D-Link devices may reset configuration to defaults; ensure you have a backup of your settings before upgrading
