CVE-2020-11968
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 · uneditedIn the web-panel in IQrouter through 3.3.1, remote attackers can read system logs because of Incorrect Access Control. Note: The vendor claims that this vulnerability can only occur on a brand-new network that, after initiating the forced initial configuration (which has a required step for setting a secure password on the system), makes this CVE invalid. This vulnerability is “true for any unconfigured release of OpenWRT, and true of many other new Linux distros prior to being configured for the first time”
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 · moderate confidenceIQrouter through version 3.3.1 has an incorrect access control vulnerability in its web panel that allows remote unauthenticated attackers to read system logs. The vulnerability is present in the default unconfigured state of the device, similar to unconfigured OpenWRT or Linux distributions.

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 device model and firmware versionAccess the router's web interface or check the device label/documentation to confirm it is an Evenroute IQrouter. Note the firmware version displayed in the system status or administration page.Affected if The device is an Evenroute IQrouter with firmware version 3.3.1 or lower.
-
Determine if the router is in its default unconfigured stateAttempt to access the router's web panel (typically at http://192.168.8.1 or the default gateway IP) without providing any login credentials. Check if the main setup wizard or initial configuration page is displayed instead of a login prompt.Affected if The web interface displays the initial setup wizard or allows access without authentication, indicating the device has not completed initial configuration.
-
Verify the logs endpoint is accessible without authenticationAttempt to access the system logs page directly (commonly at a URL path like /logs, /syslog, or similar) without providing any credentials. Observe if log data is returned.Affected if System logs or diagnostic pages are accessible without any authentication, confirming the incorrect access control vulnerability is present.
The device is affected if it is an Evenroute IQrouter with firmware version 3.3.1 or lower that remains in its default unconfigured state, allowing unauthenticated access to the web panel or system logs.

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.
From vendor dataEnsure the router undergoes forced initial configuration immediately upon deployment, including setting a strong administrative password. This mitigates the vulnerability by changing the device from its insecure default state.
