CVE-2021-38474
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 · uneditedInHand Networks IR615 Router's Versions 2.3.0.r4724 and 2.3.0.r4870 have has no account lockout policy configured for the login page of the product. This may allow an attacker to execute a brute-force password attack with no time limitation and without harming the normal operation of the user. This could allow an attacker to gain valid credentials for the product interface.
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 InHand Networks IR615 Router versions 2.3.0.r4724 and 2.3.0.r4870 lack an account lockout policy on the login page, enabling unrestricted brute-force password attacks without any time delays or account disabling after failed attempts, allowing attackers to systematically guess credentials until successful.

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.
-
Confirm device model is IR615Access the router admin interface or check device documentation/labels to verify the exact model number is InHand Networks IR615Affected if The device is not an IR615 model
-
Identify firmware versionLog into the router admin panel and navigate to the system status or firmware information page to view the installed firmware versionAffected if Firmware version is 2.3.0.r4724 or 2.3.0.r4870 exactly
-
Test for account lockout policyAttempt to log in with incorrect credentials multiple times (5-10 attempts) from the same session, observing whether the account becomes temporarily disabled, a delay is introduced, or any lockout message appearsAffected if No account lockout occurs after repeated failed attempts and login remains available without any time delays or restrictions
You are affected if you have an IR615 router running firmware version 2.3.0.r4724 or 2.3.0.r4870 and the login page allows unlimited failed attempts without triggering any account lockout or rate limiting.

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 dataImplement account lockout functionality to temporarily disable accounts after a defined number of failed login attempts, combined with rate limiting on the login endpoint; consider deploying compensating controls such as WAF rules or IP blocking at the network perimeter until vendor firmware patch is available.
