CVE-2025-6735: Juzaweb CMS Auth Bypass Vulnerability

CVE-2025-6735 Overview

CVE-2025-6735 is an improper authorization vulnerability in juzaweb CMS version 3.4.2. The flaw resides in an unknown function within the /admin-cp/imports endpoint of the Import Page component. Authenticated low-privilege users can manipulate the endpoint to perform import operations that should be restricted to administrators. The issue is classified under [CWE-266: Incorrect Privilege Assignment]. Attackers can exploit this remotely over the network with low-level credentials and no user interaction. A public proof-of-concept exists, and the vendor did not respond to disclosure attempts.

Critical Impact
Authenticated low-privilege users can access administrative import functionality, enabling unauthorized data modifications within juzaweb CMS 3.4.2.

Affected Products

juzaweb CMS version 3.4.2
Component: Import Page (/admin-cp/imports)
Vendor: juzaweb (unresponsive to disclosure)

Technical Details for CVE-2025-6735

Vulnerability Analysis

The vulnerability stems from missing authorization checks on the /admin-cp/imports route in juzaweb CMS. The endpoint exposes import functionality intended for privileged administrators but fails to validate the requester's role before processing the request. Any authenticated user with low-level privileges can invoke the import action and trigger backend logic reserved for administrative roles.

The weakness maps to [CWE-266: Incorrect Privilege Assignment]. Authorization in the affected build relies on session presence rather than role-based access control. This design pattern leaves administrative functions exposed whenever the route handler omits a role verification step.

A public proof-of-concept describing the unprivileged user import action has been published on GitHub. See the GitHub PoC for JuzaWebCMS and the VulDB #314010 entry for additional technical detail.

Root Cause

The root cause is the absence of a privilege verification check on the import handler. The application authenticates the session but does not enforce that the calling user holds an administrator role before executing the import action.

Attack Vector

The attack is performed remotely over HTTP. An attacker authenticates with any low-privilege account, then issues a request to /admin-cp/imports. Because the endpoint trusts authenticated sessions without checking the role, the import is processed and produces an outcome equivalent to administrative invocation.

No verified exploit code is included here. Refer to the linked PoC and VulDB references for reproduction steps.

Detection Methods for CVE-2025-6735

Indicators of Compromise

HTTP requests to /admin-cp/imports originating from session identifiers tied to non-administrator accounts.
Unexpected creation, modification, or import of CMS records by user accounts that lack administrative roles.
Application logs showing successful responses on import endpoints for users outside the administrator group.

Detection Strategies

Correlate web server access logs with application role data to flag low-privilege users hitting /admin-cp/ administrative paths.
Enable verbose audit logging on the Import Page component and alert on any import action by non-admin principals.
Review database change logs for import-driven inserts or updates that cannot be attributed to administrator sessions.

Monitoring Recommendations

Forward juzaweb CMS web and application logs to a centralized analytics platform for role-aware query rules.
Monitor authentication events for newly created low-privilege accounts that subsequently access administrative endpoints.
Track outbound traffic from the CMS host for anomalous file retrievals tied to import operations.

How to Mitigate CVE-2025-6735

Immediate Actions Required

Restrict network access to /admin-cp/ paths using web server rules or a reverse proxy allowlist limited to administrator source IPs.
Disable or remove low-privilege accounts that do not require CMS access until a patched build is available.
Audit recent imports in juzaweb CMS 3.4.2 and revert unauthorized changes.

Patch Information

No vendor patch is currently available. The vendor was contacted but did not respond to the disclosure. Track the VulDB #314010 CI Report and the juzaweb project repository for future fixes.

Workarounds

Place /admin-cp/imports behind an authentication layer such as HTTP Basic Auth at the reverse proxy, requiring administrator credentials before reaching the application.
Apply a web application firewall rule that blocks requests to /admin-cp/imports unless the session belongs to a verified administrator role.
Consider migrating off juzaweb CMS 3.4.2 until the maintainer issues a fix that enforces role-based authorization on the import handler.

bash

# Example NGINX rule restricting admin import access by source IP
location /admin-cp/imports {
    allow 203.0.113.10;   # administrator workstation
    deny  all;
    proxy_pass http://juzaweb_backend;
}
