CVE-2025-5426: Improper Access Controls in juzaweb CMS
A vulnerability was found in juzaweb CMS up to 3.4.2. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file /admin-cp/menus of the component Menu Page. The manipulation leads to improper access controls. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
AI Analysis
Technical Summary
CVE-2025-5426 is a medium-severity vulnerability affecting juzaweb CMS versions up to 3.4.2. The vulnerability arises from improper access controls in an unspecified functionality within the /admin-cp/menus file of the Menu Page component. This flaw allows an unauthenticated remote attacker with low privileges (PR:L) to manipulate access controls without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability at a low level (VC:L, VI:L, VA:L), indicating that the attacker could potentially access or modify restricted menu configurations or related administrative functions, but the scope and impact are limited. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N) confirms that the attack can be launched remotely over the network with low attack complexity and no need for authentication or social engineering. The vendor has not responded to the disclosure, and no patches or mitigations have been released yet. Although public exploit code has been disclosed, there are no known exploits actively used in the wild at this time. The vulnerability could allow attackers to bypass intended access restrictions on administrative menu configurations, potentially enabling unauthorized changes to the CMS interface or navigation structure, which could be leveraged for further attacks or privilege escalation if combined with other vulnerabilities.
Potential Impact
For European organizations using juzaweb CMS, this vulnerability poses a moderate risk. The improper access control could allow attackers to gain unauthorized access to administrative menu configurations, potentially disrupting website management or enabling further exploitation. This could lead to partial compromise of website integrity and availability, impacting business operations, brand reputation, and customer trust. Organizations in sectors such as government, education, media, and small-to-medium enterprises that rely on juzaweb CMS for content management are particularly at risk. The lack of vendor response and patches increases the window of exposure. While the vulnerability does not directly allow full system compromise or data exfiltration, it could serve as a stepping stone for more severe attacks if combined with other vulnerabilities or misconfigurations. The remote attack vector and no requirement for user interaction make it easier for attackers to exploit at scale, increasing the threat landscape for European entities.
Mitigation Recommendations
European organizations should immediately audit their juzaweb CMS installations to identify affected versions (3.4.0 to 3.4.2). Until an official patch is released, organizations should implement strict network-level access controls to restrict access to the /admin-cp/menus path, ideally limiting it to trusted IP addresses or VPN users. Web application firewalls (WAFs) should be configured to detect and block suspicious requests targeting the admin menu component. Administrators should monitor CMS logs for unusual access patterns or unauthorized attempts to access administrative menus. It is also advisable to enforce strong authentication and session management policies to reduce the risk of privilege escalation. Organizations should consider isolating the CMS backend from public networks where feasible. Regular backups of CMS configurations and content should be maintained to enable rapid recovery if exploitation occurs. Finally, organizations should engage with the juzaweb community or security forums to track any forthcoming patches or advisories and apply updates promptly once available.
