Description

XWEB EVO 5.6.2 through 5.8.8 contains an authentication bypass vulnerability that allows unauthenticated attackers to set the password of any account flagged must-reset-at-next-login by exploiting missing session validation in the users.lua update_password action. Attackers can reset the password of newly onboarded operator accounts, clearing the password_expiration flag and gaining an immediately usable authenticated foothold on the system. This product line reached it's end of service date in March 2026.
