CVE-2025-5424 is a medium-severity vulnerability affecting juzaweb CMS versions up to 3.4.2, specifically related to improper access controls in the Media Page component, located at the /admin-cp/media endpoint. The vulnerability arises from insufficient enforcement of access restrictions, allowing an attacker to remotely manipulate the processing of this file without requiring user interaction or elevated privileges beyond limited privileges (PR:L). The CVSS 4.0 vector indicates that the attack can be performed remotely (AV:N) with low attack complexity (AC:L), no authentication required (AT:N), and no user interaction (UI:N). The impact on confidentiality, integrity, and availability is low to limited (VC:L, VI:L, VA:L), suggesting that while the attacker can bypass some access controls, the scope of damage is somewhat constrained. The vendor has not responded to the early disclosure, and no patches or mitigations have been officially released yet. Although no known exploits are currently in the wild, the public disclosure increases the risk of exploitation attempts. The vulnerability could allow unauthorized access to media management functions, potentially leading to unauthorized data exposure or modification within the CMS environment.

For European organizations using juzaweb CMS versions 3.4.0 through 3.4.2, this vulnerability poses a risk of unauthorized access to media management functionalities, which could lead to exposure or tampering of media assets hosted on their websites. This could result in reputational damage, especially for organizations relying on their web presence for customer engagement or e-commerce. While the impact on core data confidentiality and system integrity is limited, attackers could leverage this access to further pivot within the network or conduct social engineering attacks using manipulated media content. The lack of vendor response and absence of patches increases the window of exposure, making timely mitigation critical. Organizations in sectors with high public visibility or regulatory requirements around data protection (e.g., finance, healthcare, government) could face compliance risks if the vulnerability leads to data breaches or service disruptions.

Given the absence of official patches, European organizations should implement compensating controls immediately. These include restricting access to the /admin-cp/media endpoint via network-level controls such as IP whitelisting or VPN-only access, and enforcing strict authentication and authorization policies on the CMS backend. Web application firewalls (WAFs) should be configured to detect and block anomalous requests targeting the media management component. Regular monitoring and logging of access to the /admin-cp/media path should be established to detect potential exploitation attempts. Organizations should also consider upgrading to newer versions of juzaweb CMS once patches become available or evaluate alternative CMS platforms with active security support. Additionally, conducting security audits and penetration testing focused on CMS access controls can help identify and remediate related weaknesses.
