The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of NP-P627UL, NP-P627ULG, NP-P627UL+, NP-P547UL, NP-P547ULG, NP-P607UL+, NP-CG6600UL, NP-H6271UL, NP-H5471UL, NP-P627ULH, NP-P547ULH, NP-PE455UL, NP-PE455ULG, NP-PE455WL, NP-PE455WLG, NP-PE505XLG, NP-CG6500XL, NP-CG6400UL, NP-CG6400WL, NP-CB4500XL, NP-CA4120X, NP-CA4160W, NP-CA4160X, NP-CA4200U, NP-CA4200W, NP-CA4202W, NP-CA4260X, NP-CA4300X, NP-CA4355X, NP-CD2100U, NP-CD2120X, NP-CD2300X, NP-CR2100X, NP-CR2170W, NP-CR2170X, NP-CR2200U, NP-CR2200W, NP-CR2280X, NP-CR2310X, NP-CR2350X, NP-MC302XG, NP-MC332WG, NP-MC342XG, NP-MC372X, NP-MC372XG, NP-MC382W, NP-MC382WG, NP-MC422XG, NP-ME342UG, NP-ME372W, NP-ME372WG, NP-ME382U, NP-ME382UG, NP-ME402X, NP-ME402XG, NP-P525UL, NP-P525ULG, NP-P525UL+, NP-P525WL, NP-P525WLG, NP-P525WL+, NP-P605UL, NP-P605ULG, NP-P605UL+, NP-CG6500UL, NP-CG6500WL, NP-CB4500UL, NP-CB4500WL, NP-P525ULH, NP-P525WLH, NP-P605ULH, NP-P554U, NP-P554UG, NP-P554U+, NP-P554W, NP-P554WG, NP-P554W+, NP-P474U, NP-P474UG, NP-P474W, NP-P474WG, NP-P604XG, NP-P604X+, NP-P603XG, NP-P523X+, NP-PE523XG, NP-PE523X+, NP-CF6600U, NP-CF6600W, NP-CF6700X, NP-CF6500X, NP-CB4600U, NP-P554UH, NP-P554WH, NP-P474UH, NP-P474WH, NP-P604XH, NP-P603XH, NP-PE523XH, NP-P502HL-2, NP-P502WL-2, NP-P502HLG-2, NP-P502WLG ,NP-ME401W, NP-ME361W, NP-ME331W, NP-ME301W, NP-ME401X, NP-ME361X, NP-ME331X, NP-ME301X, NP-ME401WG, NP-ME361WG, NP-ME331WG, NP-ME301WG, NP-ME401XG, NP-ME361XG, NP-ME331XG, NP-ME301XG, NP-CA4155W, NP-CA4350X, NP-CA4255X, NP-CA4155X, NP-CA4115X, NP-MC331WG, NP-MC421XG, NP-MC401XG, NP-MC371XG, NP-MC331XG, NP-MC301XG, NP-CK4155W, NP-CK4255X, NP-CK4155X, NP-CK4055X, NP-CM4150X, NP-CM4050X, NP-CK4155WG, NP-CK4255XG, NP-CK4155XG, NP-CR2165W, NP-CR2305X, NP-CR2275X, NP-CR2165X, NP-CR2155X, NP-CD2115X, NP-CD2105X, NP-CM4151X, NP-CR2276X, NP-CD2116X, NP-P502H, NP-P502W, NP-P452H, NP-P452W you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.

Official description
Improper Validation of Integrity Check Value vulnerability in Sharp Display Solutions projectors allows a attacker may create and run unauthorized firmware.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Hidden Functionality
The product contains functionality that is not documented, not part of the specification, and not accessible through an interface or command sequence that is obvious to the product's users or administrators.
How developers prevent this class of flaw
- Always verify the integrity of the product that is being installed.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: total).
- Record last changed materially (score, affected products, status or references).
