CVE-2022-41435Public exploitNetwork attack vector

Stored XSS via verbatim SSH key comments

Published Nov 3, 2022 · Updated May 5, 2025

Stored XSS in OpenWrt LuCI git-22.140.66206-02913be allows remote authenticated users to execute scripts through SSH key comments. The renderKeyItem function passed pubkey.comment directly to the strong element as markup instead of wrapping it as text content. Exploitation requires adding a crafted key through LuCI or writing /etc/dropbear/authorized_keys, after which an administrator must open the SSH-Keys page.
