CVE-2024-43424
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 request headers, resulting in an Out-of-bounds Read vulnerability. Crafted HTTP requests may cause affected products crashed.
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 out-of-bounds read vulnerability when processing HTTP request headers. Attackers can send specially crafted HTTP requests with malformed headers to trigger the vulnerability, causing the affected MFP devices to crash. This represents a denial-of-service condition with high availability impact.

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 MFP web interface or check the physical device label to confirm the exact model name (e.g., E Studio1058, BP 90c70)Affected if The model matches any of the following: Toshibatec E Studio1058, E Studio1208, E Studio908, or Sharp BP 90c70, BP 90c80, BP 70c65, BP 70c55, BP 70c45
-
Check the firmware version on Toshiba Tec devicesFor Toshiba Tec devices, access the web management interface and navigate to the System Information or Maintenance section to view the installed firmware version. Compare against the affected version strings.Affected if For E Studio1058 or E Studio1208: firmware version is t1.01.h4.00 or earlier. For E Studio908: firmware version is t2.12.h3.00 or earlier.
-
Confirm firmware version on Sharp devicesFor Sharp BP devices, access the web management interface and locate the firmware version information in the device settings or status page.Affected if Any firmware version is installed on Sharp BP 90c70, BP 90c80, BP 70c65, BP 70c55, or BP 70c45, since all versions are affected.
-
Verify HTTP management interface accessibilityAttempt to access the MFP HTTP/HTTPS management interface from a network location. Check if the web service is listening on ports 80 or 443, or check the device network configuration to confirm HTTP service is enabled.Affected if The HTTP or HTTPS management interface is reachable from network segments beyond trusted management stations.
You are affected if you have a Toshiba Tec E Studio1058, E Studio1208, or E Studio908 with firmware at or below the specified version limits, or any Sharp BP 90c70, BP 90c80, BP 70c65, BP 70c55, or BP 70c45 device, and the HTTP management interface is network-accessible.

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 patches when available. As an immediate compensating control, restrict network access to MFP management interfaces by placing them in a dedicated VLAN with firewall rules limiting HTTP/HTTPS access to trusted management stations only.
