CVE-2015-7280
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 web administration interface on ReadyNet WRT300N-DD devices with firmware 1.0.26 has a default password of admin for the admin account, which allows remote attackers to obtain administrative privileges by leveraging a LAN session.
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 ReadyNet WRT300N-DD router with firmware 1.0.26 contains a hardcoded default credential vulnerability in its web administration interface. The admin account uses a static default password of 'admin', which cannot be changed or was not changed from factory settings. Remote attackers on the LAN can trivially obtain full administrative privileges by authenticating with these default credentials.

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 the router modelAccess the router's web interface or check the device label/metadata to confirm the model is ReadyNet WRT300N-DDAffected if The device model is ReadyNet WRT300N-DD
-
Verify the firmware versionLog into the router's web administration interface and navigate to the status or system information page to confirm the firmware version is 1.0.26Affected if The firmware version is exactly 1.0.26
-
Test default credentialsAttempt to authenticate to the router's web interface using the username 'admin' and password 'admin'Affected if Authentication succeeds with the default credential admin/admin, indicating the password was not changed from factory settings
-
Verify password change capabilityCheck if the router's administration interface provides a password change or settings modification option, and whether changes persist after savingAffected if The admin password cannot be changed or the default password persists despite attempting to modify it
A user is affected if they own a ReadyNet WRT300N-DD router running firmware 1.0.26 where the default credential admin/admin still grants access and cannot be changed.

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 · scopedImmediately change the default admin password to a strong, unique password through the router's web interface. If the device does not support password changes or has been compromised, replace the device with a model that supports secure credential management.
- Change the default admin password immediately by accessing the web administration interface at the router's IP address, navigating to the administration or system settings, and setting a strong, unique password.
- Ensure the router is not directly exposed to the internet by placing it behind a NAT or firewall.
- If remote management is enabled, disable it unless VPN access is required.
- After changing the password, verify that the new credentials work and that the default admin account no longer uses the default password.
- Consider disabling the admin account if alternative administrative accounts can be created, or ensure the admin account uses a complex password that meets best practices for length and complexity.
