Description
XWEB EVO 5.6.2 through 5.8.8 contains a hardcoded credential vulnerability where the Administrator web account is configured to use password_mode daily_password with no stored password, as the Users.authenticate function in lualib_users.lua synthesizes the Administrator configuration without validating any stored secret. Attackers who can derive the MAC-based daily password can authenticate as Administrator to obtain a full admin session on the device. This product line reached it's end of service date in March 2026.
