CVE-2025-57438 is a Broken Access Control vulnerability affecting the 2wcom IP-4c device running firmware version 2.15.5. The vulnerability arises because certain sensitive endpoints, which should only be accessible after explicit administrative approval to a manager-level account, can be accessed by a manager-level user without such approval. This is possible due to the ability of a manager-level user to intercept and modify requests, thereby bypassing the intended access control mechanisms. Essentially, the device's access control logic is flawed, allowing privilege escalation or unauthorized access to sensitive functions or data that should be restricted. The vulnerability does not require an attacker to have admin-level privileges but does require at least manager-level access, which is a significant privilege but not the highest. The lack of a CVSS score and absence of known exploits in the wild suggests this is a newly published vulnerability with limited public exploitation information. However, the nature of broken access control vulnerabilities typically allows attackers to perform unauthorized actions, potentially leading to data exposure, configuration changes, or disruption of device functionality.

For European organizations, especially those relying on 2wcom IP-4c devices in their network infrastructure, this vulnerability poses a significant risk. Unauthorized access to sensitive endpoints could lead to exposure of confidential information, unauthorized configuration changes, or disruption of critical communication services. Given that 2wcom devices are often used in industrial, utility, or communication sectors, exploitation could impact operational technology environments, leading to potential service outages or safety risks. The ability for a manager-level user to bypass controls undermines internal security policies and could facilitate insider threats or lateral movement by attackers who have compromised lower privileged accounts. This could also affect compliance with European data protection regulations such as GDPR if sensitive personal data is exposed or improperly handled due to this vulnerability.

Organizations should immediately audit their deployment of 2wcom IP-4c devices to identify affected firmware versions, specifically 2.15.5. Since no patch links are currently available, it is critical to implement compensating controls: restrict manager-level account creation and usage to trusted personnel only, enforce strict network segmentation to limit access to the device management interfaces, and monitor logs for unusual access patterns or request modifications indicative of exploitation attempts. Employ network-level protections such as Web Application Firewalls (WAFs) or Intrusion Detection/Prevention Systems (IDS/IPS) to detect and block suspicious request modifications. Additionally, organizations should engage with 2wcom or their vendors to obtain firmware updates or patches addressing this vulnerability as soon as they become available. Regularly review and tighten access control policies and consider multi-factor authentication for all privileged accounts to reduce the risk of credential compromise.
