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
An access control issue in Intelbras RX1500 v2.2.9 and RX3000 v1.0.11 allows unauthenticated attackers to access the router's settings file and obtain potentially sensitive information from the current settings.

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

Intelbras RX1500 and RX3000 routers contain an authentication bypass vulnerability allowing unauthenticated attackers to directly access the device's settings configuration file. This exposes sensitive configuration data including network parameters, credentials, and other router settings without requiring any valid credentials.

MitigationApply vendor-supplied firmware patches when available. As an immediate workaround, restrict network access to the router's management interface using firewall rules or network segmentation to prevent unauthorized external access.

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 device model
    Access the router's web interface or CLI and look for the model identifier (RX1500 or RX3000) in the system information or status page
    Affected if Device is not an Intelbras RX1500 or RX3000 model - not affected
  2. Check firmware version on RX1500
    Navigate to the router's administration page, typically under 'System' > 'Firmware' or 'Status' > 'Device Info', and record the firmware version number
    Affected if Firmware version is 2.2.9 - affected
  3. Check firmware version on RX3000
    Navigate to the router's administration page, typically under 'System' > 'Firmware' or 'Status' > 'Device Info', and record the firmware version number
    Affected if Firmware version is 1.0.11 - affected
  4. Verify management interface exposure
    Check router network configuration to determine if the web management interface (HTTP/HTTPS on ports 80/443 or custom ports) is reachable from untrusted networks or the public internet
    Affected if Management interface is exposed to untrusted networks - potential exposure

A user is affected if they have an Intelbras RX1500 running firmware 2.2.9 or an RX3000 running firmware 1.0.11, especially if the router's management interface is accessible from untrusted networks.
