# Nginx UI: Account Takeover via Missing `RequireSecureSession` on User Management Endpoint in github.com/0xJacky/Nginx-UI

Nginx UI, a web interface for managing Nginx, lets any logged-in user change another user's password through the user-management endpoint because it skips the secure-session step-up check. An attacker with any authenticated account can reset the administrator's password and log in as admin.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- go:github.com/0xJacky/Nginx-UI affected < 1.9.10-0.20260703131214-23d1934099b0 fixed 1.9.10-0.20260703131214-23d1934099b0

## How to check

Check the installed Nginx UI version (Go module github.com/0xJacky/Nginx-UI) and compare it to the fixed version.

## Fix

Upgrade Nginx UI to 2.4.1 or later (the Go module fix is 1.9.10-0.20260703131214-23d1934099b0).
Rotate administrator passwords and revoke existing admin tokens after upgrading if the instance was exposed to untrusted users.

## From the sources

Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, the POST /api/users/:id user-management endpoint permits an authenticated user to change another user's password without passing RequireSecureSession, even though the self-service password-change path requires that step-up. An attacker with an authenticated account can change the initial administrator's password, invalidate existing administrator tokens, and then authenticate as the administrator. This issue is fixed in version 2.4.1.
