CVE-2026-11341
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 · uneditedA flaw has been found in D-Link DWR-M920 up to 1.1.50. The impacted element is the function sub_412DA0 of the file /boafrm/formIMEISetup. This manipulation of the argument IMEI_value causes os command injection. The attack can be initiated remotely. The exploit has been published and may be used.
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 confidenceOS command injection vulnerability in D-Link DWR-M920 routers (firmware up to 1.1.50). The IMEI_value parameter in the /boafrm/formIMEISetup web interface function (sub_412DA0) is not properly sanitized, allowing remote attackers to inject arbitrary OS commands via the vulnerable parameter.

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 device modelAccess the router web administration interface or check the device label to confirm the model is D-Link DWR-M920Affected if The device is not a D-Link DWR-M920 model
-
Check firmware versionLog into the router web interface, navigate to the status or system information page, and locate the firmware version field. Alternatively, check the download file name if you have access to the firmware binaryAffected if The firmware version is 1.1.50 or lower (any version up to and including 1.1.50)
-
Verify web interface accessibilityAttempt to access the router administrative web interface by navigating to the device IP address (typically 192.168.0.1 or 192.168.1.1) in a web browserAffected if The web interface is accessible from the network (this is required for exploitation)
-
Locate IMEI configuration functionCheck if the router web interface includes an IMEI setup or mobile network configuration page, typically under Settings, Network, or Mobile settings menusAffected if The IMEI configuration feature exists and is accessible to an authenticated user
A D-Link DWR-M920 router running firmware version 1.1.50 or lower with its web administrative interface accessible and the IMEI configuration feature present is affected by this vulnerability.
Generated from the published advisory. Verify against your own configuration.
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 dataSanitize and validate the IMEI_value input parameter to remove or escape shell metacharacters before passing to system calls; if available, apply vendor firmware patches; otherwise, restrict network access to the administrative web interface.
