CVE-2025-57130 is an Incorrect Access Control vulnerability identified in the user management component of ZwiiCMS versions up to 13.6.07. The flaw allows a remote attacker with low-level authentication to escalate their privileges by crafting a specific HTTP request that bypasses access control checks. This enables the attacker to access and modify profile data of any user, including those with administrative privileges, without requiring additional user interaction. The vulnerability impacts confidentiality and integrity severely, as unauthorized users can alter critical user information, potentially leading to full system compromise. The CVSS 3.1 score of 8.3 reflects the ease of exploitation (no user interaction, network attack vector) combined with high impact on data confidentiality and integrity. Although no public exploits have been reported yet, the vulnerability's nature and severity make it a prime target for attackers once exploit code becomes available. ZwiiCMS is a content management system used by various organizations for website and content management, and this vulnerability could allow attackers to gain control over administrative accounts, leading to further exploitation or data breaches. The vulnerability was reserved in August 2025 and published in November 2025, indicating recent discovery and disclosure. No patches or fixes are currently linked, so organizations must monitor vendor communications closely. The vulnerability does not require user interaction but does require the attacker to have some level of authenticated access, which may limit exposure but still poses a significant risk in environments with many low-privilege users.

For European organizations, the impact of CVE-2025-57130 is substantial. Organizations using ZwiiCMS for managing websites or internal portals face risks of unauthorized privilege escalation, potentially leading to full administrative control by attackers. This can result in data breaches, defacement of websites, unauthorized data manipulation, and disruption of services. Confidentiality is compromised as attackers can access sensitive user data, including administrator profiles. Integrity is also at risk since attackers can modify user information, potentially creating backdoors or persistent access. Availability impact is indirect but possible if attackers disrupt administrative functions or deploy malicious content. The vulnerability's exploitation could undermine trust in affected organizations, especially those handling sensitive or regulated data under GDPR. The requirement for authenticated access means insider threats or compromised low-privilege accounts could be leveraged, increasing the risk in environments with weak authentication controls. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score demands urgent attention.

1. Monitor ZwiiCMS vendor channels for official patches or updates addressing CVE-2025-57130 and apply them immediately upon release. 2. Implement strict access control policies limiting the number of users with authenticated access to the CMS, especially low-privilege accounts. 3. Enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of account compromise. 4. Conduct regular audits of user permissions and profile changes to detect unauthorized modifications early. 5. Utilize web application firewalls (WAFs) to detect and block anomalous HTTP requests that may attempt to exploit this vulnerability. 6. Segment CMS management interfaces from general network access to reduce exposure. 7. Educate administrators and users about the risks of privilege escalation and encourage reporting of suspicious activity. 8. Consider temporary compensating controls such as disabling profile editing for low-privilege users until a patch is available. 9. Review and harden logging and monitoring to ensure detailed records of user management activities are maintained for forensic analysis.
