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 DIR-815 devices with firmware before 2.07.B01 allow remote attackers to obtain sensitive information by leveraging cleartext storage of the administrative password.

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 DIR-815 router stores the administrative password in cleartext within the device firmware/configuration. This allows remote attackers who can access the device (either directly or through intercepted traffic/device compromise) to obtain the plaintext administrative credentials, granting full administrative access to the device.

MitigationUpdate D-Link DIR-815 firmware to version 2.07.B01 or later to remediate the cleartext password storage vulnerability. After updating, change the administrative password as a precautionary measure.

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 interface or check the device label to confirm the model is D-Link DIR-815
    Affected if The device is not a D-Link DIR-815 router - this CVE only affects that specific model
  2. Check the firmware version
    Log into the router web interface and navigate to Status or System Info page to view the firmware version, or use the command 'cat /proc/version' if you have telnet/ssh access
    Affected if The firmware version is less than 2.07.B01 (for example, 2.06, 2.05, 1.00, etc.)
  3. Locate the configuration file
    Access the router's configuration backup file (usually named 'config.bin' or 'settings.bin' available through the web interface's backup/restore function), or if you have shell access, check /etc/config or similar configuration directories
    Affected if You can access the router's configuration file through backup export, telnet/ssh, or firmware extraction
  4. Inspect for cleartext password storage
    Open the configuration file in a text editor or use 'strings' command to search for the admin password. Look for the <password> or <password_enc> XML tags and check if the value appears as plaintext rather than a hashed or encrypted value
    Affected if The administrative password appears in clear, readable text within the configuration file (for example: <password>MyPassword123</password> instead of a hash like <password_enc>3f1831d...</password_enc>)

If the device is a D-Link DIR-815 running firmware version below 2.07.B01 AND the configuration file contains the admin password in plaintext, the environment is affected by CVE-2015-0152.

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 2.07.b01 or later
Fixed in 2.07.b01
Interim mitigation

Update D-Link DIR-815 firmware to version 2.07.B01 or later to remediate the cleartext password storage vulnerability. After updating, change the administrative password as a precautionary measure.

Recommended fix Moderate confidence

Firmware 2.07.B01 or later for D-Link DIR-815

  1. 1. Identify the current firmware version of the D-Link DIR-815 device by accessing the web management interface or checking the device status page.
  2. 2. Navigate to the official D-Link support website (support.dlink.com) and locate the DIR-815 product support page.
  3. 3. Download firmware version 2.07.B01 or later from the official D-Link support page - ensure the firmware is sourced from D-Link's official website to avoid compromised images.
  4. 4. Backup the current device configuration through the web management interface (System > Config > Backup Settings) before applying the update.
  5. 5. Access the firmware upgrade section (Tools > Firmware) in the web management interface.
  6. 6. Upload the downloaded firmware file (.bin) and allow the device to complete the upgrade process - do not power off the device during this process.
  7. 7. After the device reboots, verify the new firmware version is installed and restore the backed-up configuration if needed.
  8. 8. Change the administrative password after the upgrade as a security best practice, since the vulnerability involved cleartext password storage.
Caveat Firmware upgrades may reset device configuration to defaults; restore from backup after upgrade and reconfigure any custom settings
