CVE-2026-24107
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 · uneditedAn issue was discovered in Tenda W20E V4.0br_V15.11.0.6. Failure to validate the value of `usbPartitionName`, which is directly used in `doSystemCmd`, may lead to critical command injection vulnerabilities.
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 Tenda W20E V4.0br_V15.11.0.6 firmware contains a command injection vulnerability in its USB partition naming functionality. The `usbPartitionName` parameter is used directly in the `doSystemCmd` function without any input validation or sanitization, allowing attackers to inject arbitrary OS commands through the web interface.

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 Tenda W20EAccess the device web interface or check the physical label to verify the model number is W20EAffected if The device is not a Tenda W20E model, then this specific CVE does not apply
-
Check firmware versionLog into the device web interface and navigate to System Status or Firmware Upgrade page to view the installed firmware version, or use the command 'cat /proc/version' via telnet/SSH if availableAffected if The installed firmware version is exactly 15.11.0.6, then the device is affected by this vulnerability
-
Verify USB sharing is enabledLog into the web interface and check the USB sharing or USB settings configuration page to see if any USB feature is enabledAffected if USB sharing functionality is enabled on the device, then the vulnerable code path can be triggered
-
Confirm web management interface accessibilityAttempt to access the device login page at the device IP address via HTTP/HTTPSAffected if The web management interface is reachable from the network, the command injection vector is accessible
A defender is affected if they have a Tenda W20E device running firmware version 15.11.0.6 with the USB sharing feature enabled and the web interface accessible on their network.

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 dataRestrict access to the device's web management interface to trusted networks only; disable USB sharing features if not needed; apply vendor firmware patches when available.
