CVE-2020-6091Network attack vector

Unauthenticated configuration access via unprotected Web Control URLs

Published May 22, 2020 · Updated Aug 4, 2024

Authentication bypass in Epson BrightLink Pro 1470Ui firmware 1.08 and earlier allows remote attackers to read and modify settings. The Web Control handler serves specific /cgi-bin/webconf page values without enforcing authentication, exposing projector details and read/write controls. Network access to the projector is sufficient; reachable pages disclose network and directory settings and permit configuration changes, reset, or shutdown.
