CVE-2024-45829
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 provide the web page to download data, where query parameters in HTTP requests are improperly processed and 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 · high confidenceSharp and Toshiba Tec MFPs have an out-of-bounds read vulnerability in their web-based data download functionality. The vulnerability is caused by improper processing of query parameters in HTTP requests. Crafted HTTP requests with malicious query parameters can trigger the out-of-bounds read, causing the affected MFP 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 MFP modelAccess the device's web interface or check the device label/menu to confirm the exact model (e.g., ToshibaTec E Studio1058, Sharp BP 90c70)Affected if Model matches one of the affected products listed in the CVE
-
Check firmware versionLog into the MFP web interface and navigate to the firmware/version information page, or access it via the device's control panel menu under System Information or Device StatusAffected if For ToshibaTec models: firmware version is <= t1.01.h4.00 (for 1058/1208) or <= t2.12.h3.00 (for 908). For Sharp models: any version since all versions are affected
-
Verify web interface is enabledAttempt to access the MFP by navigating to its IP address in a web browser (http://[device-ip]). If a login page or web panel loads, the web interface is enabledAffected if Web interface is accessible and responds to HTTP requests
-
Check network exposure of web interfaceReview firewall rules or network configuration to determine if the MFP web port (typically 80 or 443) is exposed to untrusted networksAffected if Web interface is reachable from networks other than trusted internal segments
User is affected if they have a matching MFP model with an affected firmware version AND the web-based data download functionality is accessible (web interface enabled and network-adjacent attackers can reach it).

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. If patches are unavailable, restrict network access to the MFP web interfaces using firewalls or network segmentation to minimize exposure to unauthenticated HTTP requests.
