What to do

  1. Check which version of NP-P502HL-2, NP-P502WL-2, NP-P502HLG-2, NP-P502WLG, NP-P502H, NP-P502W, NP-P452H, NP-P452W, NP-P502HG, NP-P502WG, NP-P452HG, NP-P452WG, NP-P502H+, NP-P502W+, NP-CR5450H, NP-CR5450W, NP-P502HL, NP-P502WL, NP-P502HLG, NP-P502WLG, NP-P502HL+, NP-P502WL+, NP-CR5450HL, NP-CR5450WL, NP-UM352W, NP-UM352WG, NP-UM352W+ you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on sharp-displays.jp.sharp for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

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: Improper Validation of Integrity Check Value

The product does not validate or incorrectly validates the integrity check values or checksums of a message.

How developers prevent this class of flaw

  • The protocol specification describes the algorithm used for calculating the checksum. It is then a matter of implementing the calculation and verifying that the calculated checksum and the received checksum match.
