CVE-2025-11541
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 · uneditedStack-based Buffer Overflow vulnerability in Sharp Display Solutions projectors allows a attacker may execute arbitrary commands and programs.
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 confidenceA stack-based buffer overflow vulnerability exists in Sharp Display Solutions projectors. This memory corruption flaw allows an attacker to overwrite return addresses or adjacent stack frames, enabling execution of arbitrary commands and programs on the affected device.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 modelAccess the projector's on-screen display (OSD) menu, check the product label on the device, or query the device via network (e.g., HTTP management page, SNMP, or manufacturer discovery tool). Look for the model name printed on the unit or displayed in the system information menu.Affected if Model name matches Sharp Np P502h, P502w, P452h, P452w, P502hg, P502wg, P452hg, or P452wg
-
Verify network interface statusCheck the projector's network settings via OSD menu or management web interface. Determine if the wired network port or wireless adapter is connected and enabled.Affected if Network interface is enabled and the projector has an IP address assigned
-
Confirm management services are exposedProbe common management ports on the projector's IP address (e.g., HTTP on 80/443, Telnet, SSH, or manufacturer-specific ports). Use nmap, netcat, or curl to check for open management services.Affected if Any management or network service (HTTP, HTTPS, Telnet, SSH, or proprietary) is reachable from the network
You are affected if you have any of the eight listed Sharp NP projector models (P502h, P502w, P452h, P452w, P502hg, P502wg, P452hg, P452wg) with network connectivity enabled, since all firmware versions contain the 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 dataIsolate projector network segments from untrusted networks, apply vendor-supplied firmware updates when available, and monitor for unauthorized access attempts.
