NVD · unedited
D-Link DIR-2150 GetDeviceSettings Target Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DIR-2150 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SOAP API interface, which listens on TCP port 80 by default. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-20558.

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

D-Link DIR-2150 router contains a command injection vulnerability in the SOAP API interface on TCP port 80. The flaw results from improper validation of user-supplied strings before being used in system calls, allowing unauthenticated attackers to execute arbitrary code as root.

MitigationApply the vendor-supplied firmware patch when available; as an interim measure, restrict network access to the device's web interface using firewall rules or network segmentation to prevent unauthenticated attackers from reaching the SOAP API.

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 is D-Link DIR-2150
    Access the router web interface or check the device label/marketing to identify the exact model number. The vulnerability only affects the DIR-2150 model.
    Affected if The device is not a D-Link DIR-2150 router
  2. Identify the installed firmware version
    Log into the router web interface and navigate to the Status or Management section to view the firmware version. Compare this version number against the affected range of < 1.06.
    Affected if The installed firmware version is less than 1.06
  3. Verify SOAP API is accessible on TCP port 80
    Attempt to access the device's web interface via HTTP on port 80, or inspect the device's listening network services. The vulnerability exists in the SOAP API service running on this port.
    Affected if TCP port 80 is open and responding with the router's web interface or SOAP endpoints
  4. Assess network exposure to unauthenticated attackers
    Determine if the router's management interface (port 80) is directly exposed to untrusted networks such as the public internet or is behind adequate network access controls. Check firewall rules or network placement.
    Affected if The device's web interface on port 80 is accessible from untrusted network segments without authentication barriers

The environment is affected if the device is a D-Link DIR-2150 router running firmware version less than 1.06 with its SOAP API on TCP port 80 exposed to unauthenticated network access.

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.

dbcve · scoped
Upgrade available Upgrade to 1.06 or later
Fixed in 1.06
Interim mitigation

Apply the vendor-supplied firmware patch when available; as an interim measure, restrict network access to the device's web interface using firewall rules or network segmentation to prevent unauthenticated attackers from reaching the SOAP API.

Recommended fix Moderate confidence

D-Link DIR-2150 Firmware version 1.06 or later

  1. 1. Download the latest firmware version 1.06 or later from the official D-Link support website for the DIR-2150 router
  2. 2. Access the router's web management interface by navigating to the device's IP address (typically 192.168.0.1)
  3. 3. Log into the router administrative interface with valid credentials
  4. 4. Navigate to the 'Management' or 'System' settings section
  5. 5. Locate the 'Firmware Upgrade' or 'Software Update' option
  6. 6. Click 'Browse' or 'Choose File' and select the downloaded firmware file
  7. 7. Click 'Upload' or 'Upgrade' to begin the firmware update process
  8. 8. Wait for the upgrade to complete - do not power off the router during this process
Caveat Firmware upgrades may reset configuration to defaults; backup current configuration before upgrading and restore after completion
