CVE-2025-5426 Overview
CVE-2025-5426 is an improper access control vulnerability in juzaweb CMS versions up to 3.4.2. The flaw resides in the /admin-cp/menus endpoint of the Menu Page component. Authenticated but unprivileged users can manipulate menu configurations that should be restricted to administrators. The weakness maps to [CWE-266] Incorrect Privilege Assignment. Public disclosure occurred without vendor response, and the exploit technique is publicly documented.
Critical Impact
Low-privileged remote users can modify administrative menu configurations in juzaweb CMS, undermining the CMS access control model and enabling unauthorized content changes.
Affected Products
- juzaweb CMS versions up to and including 3.4.2
- Deployments exposing /admin-cp/menus to authenticated non-admin users
- Self-hosted juzaweb CMS installations without compensating access controls

Technical Details for CVE-2025-5426
Vulnerability Analysis
The vulnerability affects the Menu Page component reachable through the /admin-cp/menus path in juzaweb CMS. The application fails to enforce role-based authorization checks on menu management actions. An authenticated user with minimal privileges can issue requests that alter menu structures reserved for administrators. This breaks the trust boundary between standard users and privileged operators.
The issue is classified under [CWE-266] Incorrect Privilege Assignment. The vendor did not respond to disclosure attempts before public release. No official patch or advisory has been published at the time of NVD indexing. See the GitHub Report on Juzaweb CMS for the original technical writeup.
Root Cause
The root cause is missing or insufficient authorization enforcement on menu management routes inside the admin control panel. The application likely validates that a session exists but does not verify that the account holds an administrative role. This gap allows any authenticated principal to reach privileged functionality.
Attack Vector
Exploitation requires network access to the CMS and valid low-privileged credentials. An attacker authenticates as a standard user, then sends crafted HTTP requests to /admin-cp/menus to add, modify, or remove menu entries. No user interaction is required beyond the attacker's own session. Refer to the VulDB entry #310759 for scoring context.
No verified proof-of-concept code is available; consult the GitHub Report on Juzaweb CMS for reproduction details.
Detection Methods for CVE-2025-5426
Indicators of Compromise
- Unexpected changes to CMS navigation menus, including new links pointing to external or unfamiliar domains
- HTTP requests to /admin-cp/menus originating from user sessions that do not hold administrative roles
- Audit log entries showing menu create, update, or delete actions attributed to non-admin accounts
Detection Strategies
- Correlate web server access logs against the application role database to flag privileged endpoint access by low-privileged users
- Baseline legitimate administrator source IP ranges and alert on /admin-cp/menus requests from outside that set
- Enable database-level auditing on the menu table to record unauthorized write operations
Monitoring Recommendations
- Forward web and application logs to a centralized analytics platform for role-versus-endpoint correlation
- Monitor for enumeration patterns against /admin-cp/* paths that may indicate broader access control probing
- Alert on rapid sequential POST or PUT requests to admin panel endpoints from a single session
How to Mitigate CVE-2025-5426
Immediate Actions Required
- Restrict access to /admin-cp/* routes at the reverse proxy or web application firewall layer to trusted administrator IP ranges
- Audit all existing user accounts and remove unused or low-trust accounts that could be leveraged for exploitation
- Review current menu structures for unauthorized changes and restore known-good baselines from backup
Patch Information
At the time of publication, the vendor has not released a patch or public advisory. The disclosure record notes that juzaweb was contacted but did not respond. Monitor the juzaweb project references for future updates and apply fixes when available.
Workarounds
- Enforce authorization at a proxy layer such as NGINX or a WAF by requiring administrator group membership before proxying to /admin-cp/menus
- Disable self-registration or tightly control account provisioning to limit the pool of authenticated attackers
- Apply file-system permissions and database role restrictions so the CMS process cannot silently alter production menu configurations without an audit trail
