Wi-Fi compromise via misleading network configuration UI
Published Apr 26, 2021 · Updated Aug 3, 2024
Incorrect security UI in Google Chrome on ChromeOS before 90.0.4430.72 allows remote attackers to compromise Wi-Fi connection security. The published record identifies Network Config UI and a malicious wireless access point, but Google has not disclosed which security indicator or decision is rendered incorrectly. Exploitation requires user interaction with an attacker-controlled access point; the documented consequence is limited to Wi-Fi connection integrity.
