CVE-2022-28109Public exploitNetwork attack vector

Remote code execution via arbitrary Host acceptance

Published Apr 15, 2022 · Updated Aug 3, 2024

DNS rebinding in Selenium Grid before 4.0.0-alpha-7 allows remote attackers to execute arbitrary code through its WebDriver endpoint. The server accepts WebDriver requests carrying arbitrary Host headers, so a malicious origin can rebind its name to the Grid and create a session. Exploitation requires a browser user to visit an attacker-controlled rebinding site, after which the site can issue WebDriver commands with the Grid host's privileges.
