Vulnerability Spotlight: Authentication bypass vulnerability in some Epson projectors

Summary: Cisco Talos disclosed an authentication bypass in the web control functionality of the Epson EB-1470Ui projector, where a crafted series of HTTP requests or a malicious web page can bypass authentication and give an attacker full read/write configuration access. Talos released the finding after Epson did not patch it within Cisco's 90-day deadline and stopped responding to follow-up requests, though Epson later patched the issue in October 2020.
Why it matters: The vulnerable device is a projector on the corporate network, and the vendor went silent after acknowledging the report, leaving a window where full configuration access was available to anyone who could lure a user to a crafted page.
