CVE-2024-42420
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 contain multiple Out-of-bounds Read vulnerabilities, due to improper processing of keyword search input and improper processing of SOAP messages. 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 MFPs contain out-of-bounds read vulnerabilities caused by improper validation of keyword search input and SOAP message processing. Remote attackers can send crafted HTTP requests to trigger these flaws, causing the affected devices to crash.

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 modelAccess the device web interface or check the device label/display to confirm the exact model number (e.g., E Studio1058, BP 90c70)Affected if The model is one of: Toshibatec E Studio1058, E Studio1208, E Studio908, Sharp BP 90c70, BP 90c80, BP 70c65, BP 70c55, or BP 70c45
-
Check the firmware versionLog into the MFP admin web interface and navigate to the Device Information or System Settings page to view the installed firmware versionAffected if For Toshibatec models: firmware version is t1.01.h4.00 or lower (E Studio1058/1208), or t2.12.h3.00 or lower (E Studio908); for Sharp models: any firmware version since all versions are affected
-
Verify network accessibility of management interfacesAttempt to access the MFP web interface over HTTP/HTTPS from a remote location or check firewall rules allowing external access to ports 80, 443, or the MFP management portAffected if The MFP management interface is exposed to untrusted networks without firewall restrictions
-
Confirm if keyword search or SOAP services are enabledCheck the MFP configuration pages for web services settings; look for Enable Keyword Search, Web Scan, or SOAP service options in the administrative settingsAffected if Keyword search functionality or SOAP-based web services are enabled and accessible over the network
-
Review HTTP request logging for suspicious patternsCheck MFP logs or network traffic logs for malformed HTTP requests containing unusual keyword search parameters or malformed SOAP XML messagesAffected if Logs show evidence of crafted keyword search or SOAP requests that may have triggered the vulnerability
You are affected if your MFP matches one of the listed models and your firmware version falls within or below the specified version ranges (or any version for Sharp models), especially if the management interface or keyword search/SOAP features are network-accessible.
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 dataApply vendor-supplied firmware updates when available; until then, restrict network access to MFP management interfaces and implement Web Application Firewall rules to block malformed keyword search and SOAP requests.
