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
Cross site request forgery (CSRF) vulnerability in KeeneticOS before 4.3 at "/rci" API endpoint allows attackers to take over the device via adding additional users with full permissions by managing the victim to open page with exploit.

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

CSRF vulnerability in KeeneticOS web interface at the /rci API endpoint allows remote attackers to inject new administrative users by tricking authenticated administrators into visiting malicious pages, enabling full device takeover.

MitigationUpgrade KeeneticOS to version 4.3 or later. Avoid browsing untrusted sites while logged into the router admin panel as a temporary workaround.

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 KeeneticOS version
    Access the router's web admin panel and navigate to System > Overview or System > Firmware to view the current OS version. Alternatively, use the command line interface (CLI) and run 'show version' or 'system show version' to display the firmware version.
    Affected if The displayed version is lower than 4.3 (for example, 4.2.x, 4.1.x, or earlier)
  2. Confirm web interface is accessible
    Verify that the KeeneticOS web interface (HTTP/HTTPS on ports 80 or 443) is enabled and reachable on the device. This can be confirmed by attempting to access the router's IP address in a web browser or checking the web server status via CLI with 'show interface' or 'show http' commands.
    Affected if The web interface is enabled and accessible on the network (this is required for the /rci endpoint to be exploitable)
  3. Review administrative user accounts
    Log into the router admin panel and navigate to Users and Passwords or Access Control to list all configured administrator accounts. Alternatively, access the CLI and use 'show administrators' or check the configuration via 'show running-config' to enumerate all user accounts with administrative privileges.
    Affected if There are unexpected or unauthorized administrative user accounts present that were not created by the legitimate administrator

The environment is affected if KeeneticOS version is below 4.3, the web interface is enabled, and either the version check confirms < 4.3 or suspicious administrative accounts are detected as a potential post-exploitation indicator.

Upgrade available Upgrade to 4.3 or later
Fixed in 4.3
Interim mitigation

Upgrade KeeneticOS to version 4.3 or later. Avoid browsing untrusted sites while logged into the router admin panel as a temporary workaround.

Recommended fix High confidence

KeeneticOS 4.3

  1. Download the KeeneticOS 4.3 firmware from the official Keenetic download page
  2. Access the Keenetic router web interface
  3. Navigate to System settings or Administration section
  4. Locate the Firmware/Configuration upgrade option
  5. Upload and apply the KeeneticOS 4.3 firmware file
  6. Wait for the device to reboot and verify the upgrade was successful
  7. Confirm the /rci endpoint is now protected against CSRF attacks
