CVE-2025-5425: Juzaweb CMS Auth Bypass Vulnerability

CVE-2025-5425 Overview

CVE-2025-5425 is an improper access control vulnerability in juzaweb CMS versions up to and including 3.4.2. The flaw resides in an unknown function of the /admin-cp/theme/editor/default endpoint, part of the Theme Editor Page component. Authenticated low-privileged users can reach administrative theme editing functionality that should be restricted to privileged accounts. The issue is classified under [CWE-266] Incorrect Privilege Assignment. Public disclosure occurred without a vendor response, and no official patch has been published at the time of writing.

Critical Impact
Authenticated low-privileged users can access the Theme Editor and modify theme files, potentially leading to unauthorized content changes or code injection through theme templates.

Affected Products

juzaweb CMS versions up to and including 3.4.2
Theme Editor Page component (/admin-cp/theme/editor/default)
Installations exposing the admin control panel to standard authenticated users

Technical Details for CVE-2025-5425

Vulnerability Analysis

The vulnerability affects the Theme Editor endpoint at /admin-cp/theme/editor/default in juzaweb CMS. The application fails to enforce role-based authorization on this administrative route. Any authenticated account, including unprivileged users, can invoke the theme editor and reach functionality intended for administrators. The attack is remote and requires only low privileges, with no user interaction beyond an authenticated session. Public disclosure has occurred, but the vendor has not responded to the report according to the submitter.

Root Cause

The root cause is a missing or incorrectly implemented authorization check on the theme editor route [CWE-266]. The controller handling /admin-cp/theme/editor/default verifies that the caller is authenticated but does not validate that the caller holds an administrator or theme-management role. As a result, privilege boundaries between standard users and administrators collapse for this feature.

Attack Vector

An attacker first obtains any valid user account on the target juzaweb CMS instance. From an authenticated browser session, the attacker navigates directly to the /admin-cp/theme/editor/default URL. Because the endpoint does not check role membership, the theme editor loads and exposes editing capabilities. Depending on the exact functionality reachable through the editor, an attacker may be able to modify theme templates, which in some CMS platforms can be leveraged to persist malicious content or scripts served to other users.

See the GitHub Report on JuzaWeb CMS and VulDB entry 310758 for the original technical write-up.

Detection Methods for CVE-2025-5425

Indicators of Compromise

HTTP requests to /admin-cp/theme/editor/default originating from user accounts that are not members of an administrative role
Unexpected modifications to theme template files, layouts, or view partials on the CMS filesystem
New or altered JavaScript, PHP, or template code served from theme directories without a corresponding administrator change record

Detection Strategies

Enable web server access logging on all /admin-cp/* routes and correlate the requesting session cookie or user ID with the account's role assignment
Alert on any 200-status response to /admin-cp/theme/editor/default where the authenticated user is not a member of the administrator group
Baseline theme file hashes and generate alerts on any change outside a defined maintenance window

Monitoring Recommendations

Forward juzaweb application logs and web server logs to a centralized logging platform for role-versus-endpoint correlation
Monitor filesystem integrity for the themes/ and resources/views/ directories using file integrity monitoring tools
Track authentication events for newly created low-privilege accounts followed by requests to administrative routes

How to Mitigate CVE-2025-5425

Immediate Actions Required

Restrict access to /admin-cp/* routes at the reverse proxy or web server layer using IP allow-lists or VPN-only access until a vendor fix is available
Audit all existing juzaweb CMS user accounts and disable or remove any unnecessary low-privileged accounts
Review theme directory contents for unauthorized modifications and restore known-good files from backup where changes cannot be attributed to an administrator

Patch Information

No vendor patch has been published for CVE-2025-5425 as of the last NVD update on 2026-06-17. The reporter noted that juzaweb was contacted but did not respond. Operators should track the VulDB entry 310758 and the vendor's release channels for updates.

Workarounds

Block requests to /admin-cp/theme/editor/default at a web application firewall (WAF) or reverse proxy for any session not belonging to an administrator account
Enforce network-level access control on the entire admin control panel path so that only trusted management networks can reach it
Apply strict file permissions on theme directories to prevent the web server user from writing to template files outside deployment operations

bash

# Example nginx location block restricting the vulnerable route to an admin subnet
location = /admin-cp/theme/editor/default {
    allow 10.10.0.0/24;   # admin management network
    deny  all;
    proxy_pass http://juzaweb_backend;
