CVE-2025-5423 is a medium-severity vulnerability affecting juzaweb CMS versions up to 3.4.2. The vulnerability arises from improper access controls in the General Setting Page component, specifically within the /admin-cp/setting/system/general endpoint. This flaw allows an unauthenticated remote attacker to manipulate access controls, potentially gaining unauthorized access or performing actions reserved for privileged users. The vulnerability does not require user interaction or authentication, which increases its risk profile. However, the CVSS score of 5.3 reflects that the impact on confidentiality, integrity, and availability is limited to low levels, and the attack complexity is low. The vendor has not responded to early notifications, and no patches or fixes have been released at the time of disclosure. Although no known exploits are currently observed in the wild, the public disclosure of the exploit code increases the likelihood of exploitation attempts. The vulnerability affects a critical administrative interface, which if exploited, could lead to unauthorized configuration changes, potentially disrupting the CMS operation or exposing sensitive configuration data. Given the CMS nature, exploitation could also facilitate further attacks on hosted websites or backend systems.

For European organizations using juzaweb CMS, this vulnerability poses a tangible risk to the security and integrity of their web content management systems. Unauthorized access to the administrative settings could lead to configuration tampering, data leakage, or service disruption. This could impact confidentiality of sensitive organizational data and integrity of published content. Organizations in sectors with strict data protection regulations, such as finance, healthcare, or government, could face compliance risks and reputational damage if exploited. Additionally, compromised CMS instances could serve as footholds for broader network intrusions or malware distribution. The lack of vendor response and absence of patches increase the urgency for European entities to implement mitigations proactively. The medium severity suggests that while the vulnerability is not critical, it should not be ignored, especially in high-value or sensitive environments.

Since no official patches are available, European organizations should implement compensating controls immediately. These include restricting access to the /admin-cp/setting/system/general endpoint via network-level controls such as IP whitelisting or VPN-only access. Web application firewalls (WAFs) should be configured to detect and block suspicious requests targeting this endpoint. Organizations should audit and monitor access logs for unusual activity around the administrative interface. If possible, disable or limit the use of the affected General Setting Page until a patch is released. Regular backups of CMS configurations and content should be maintained to enable recovery in case of compromise. Additionally, organizations should consider isolating the CMS environment from other critical infrastructure to contain potential breaches. Finally, maintain vigilance for vendor updates or community patches and apply them promptly once available.
