CVE-2025-11543
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 · uneditedImproper Validation of Integrity Check Value vulnerability in Sharp Display Solutions projectors allows a attacker may create and run unauthorized firmware.
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 Display Solutions projectors contain an improper validation of integrity check value vulnerability in their firmware validation mechanism. This allows an attacker to create and run unauthorized firmware by bypassing the integrity check that should verify firmware authenticity before execution.

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 projector modelLocate the product label on the projector or access the projector's system information menu to confirm the exact model number (e.g., NP-P502h, NP-P452w, etc.)Affected if Model matches any of: NP-P502h, NP-P502w, NP-P452h, NP-P452w, NP-P502hg, NP-P502wg, NP-P452hg, NP-P452wg
-
Check installed firmware versionAccess the projector's firmware/version information through the on-screen menu (typically under Setup > Information or System Information) or via the projector's web management interface if availableAffected if Any firmware version is installed on an affected model (all versions are vulnerable)
-
Verify firmware validation mechanism statusCheck the projector's security or firmware settings menu for options related to firmware integrity validation, signature verification, or secure boot. Look for settings named 'Firmware Verification', 'Secure Mode', or similar.Affected if The firmware validation/integrity check mechanism exists but can be bypassed or is improperly implemented (the vulnerability is in the validation itself)
-
Test firmware update process integrityAttempt to initiate a firmware update using the projector's standard update procedure and observe if any integrity or signature errors are raised when using an unmodified official firmware fileAffected if Firmware updates complete without integrity or signature validation errors being raised (indicating the validation may be bypassed)
If the projector model is any of the NP-P50x or NP-P45x series variants and the firmware validation mechanism is present, the environment is affected because all versions of these products have the improper integrity check vulnerability.

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-provided firmware updates when available and ensure only signed firmware from trusted sources is deployed to affected projector devices.
