AI Analysis
Technical Summary
CVE-2025-5429 is a medium-severity vulnerability affecting juzaweb CMS versions up to 3.4.2. The vulnerability arises from improper access controls in the /admin-cp/plugin/install component of the Plugins Page. This flaw allows an unauthenticated remote attacker with low privileges to manipulate access controls, potentially enabling unauthorized actions within the plugin installation functionality. Although the exact code details are unspecified, the vulnerability permits remote exploitation without user interaction or authentication, indicating a design or implementation flaw in access control enforcement. The vendor has not responded to early disclosure attempts, and no patches or fixes have been released as of the publication date. 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) reflects network attack vector, low attack complexity, no authentication required, and limited impact on confidentiality, integrity, and availability. No known exploits are currently active in the wild, but public disclosure increases the risk of exploitation attempts.
Potential Impact
For European organizations using juzaweb CMS, this vulnerability poses a risk of unauthorized access to plugin installation functions, which could lead to unauthorized plugin deployment or modification. This may result in further compromise, such as privilege escalation, data leakage, or service disruption if malicious plugins are installed. Given the CMS's role in website content management, exploitation could impact website integrity and availability, damaging organizational reputation and potentially exposing sensitive data. The lack of vendor response and patches increases exposure time, raising the risk for organizations that have not implemented compensating controls. Organizations in sectors relying heavily on web presence, such as e-commerce, media, and public services, may face operational and reputational impacts if exploited.
Mitigation Recommendations
Since no official patches are available, European organizations should implement immediate compensating controls. These include restricting access to the /admin-cp/plugin/install endpoint via network-level controls such as IP whitelisting or VPN-only access, and deploying web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting plugin installation. Regularly monitoring web server logs for unusual access patterns to the vulnerable endpoint is critical. Organizations should also consider disabling plugin installation functionality if not required or isolating the CMS environment to limit potential lateral movement. Promptly updating juzaweb CMS once a vendor patch is released is essential. Additionally, conducting internal security assessments to identify any unauthorized changes or signs of compromise related to plugin management is recommended.
