CVE-2024-47406
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 · uneditedSharp and Toshiba Tec MFPs improperly process HTTP authentication requests, resulting in an authentication bypass vulnerability.
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 confidenceSharp and Toshiba Tec Multi-Function Printers (MFPs) contain an authentication bypass vulnerability where HTTP authentication requests are improperly processed, allowing unauthenticated attackers to bypass authentication mechanisms and potentially gain administrative access to the device.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 MFP device modelAccess the device web interface or check the physical label to confirm the exact model (e.g., Sharp BP 90c70, Toshiba Tec E Studio1058)Affected if The device is one of the following: Sharp BP 90c70, BP 90c80, BP 70c65, BP 70c55, BP 70c45, or Toshiba Tec E Studio1058, E Studio1208, or E Studio908
-
Check the firmware version on Sharp devicesLog into the web management interface and navigate to the firmware or system information page to retrieve the firmware versionAffected if The device is a Sharp BP model (all versions of these models are affected)
-
Check the firmware version on Toshiba Tec devicesAccess the web interface or print a configuration page to find the firmware version (e.g., t1.01.h4.00, t2.12.h3.00)Affected if The firmware version is t1.01.h4.00 or earlier for E Studio1058/E Studio1208, or t2.12.h3.00 or earlier for E Studio908
-
Verify HTTP management interface exposureAttempt to access the device HTTP interface from an untrusted network segment using a browser (e.g., http://<device-ip>)Affected if The HTTP management interface is reachable from network segments that should not have administrative access
-
Confirm network accessibility of the MFPUse nmap or similar tool to verify if ports 80 or 443 are open and accessible from untrusted networks: nmap -p 80,443 <device-ip>Affected if The device HTTP/HTTPS ports are exposed to untrusted or public networks without firewall filtering
A user is affected if they have a Sharp BP 70c/90c series device (any firmware version) or a Toshiba Tec E Studio1058/1208/908 device with firmware at or below the affected versions, and the device HTTP interface is accessible from an untrusted 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 dataApply vendor-supplied firmware updates when available and restrict network access to MFP devices using firewall rules or network segmentation to limit exposure to untrusted networks.
