CVE-2023-4061 is a vulnerability identified in the wildfly-core component of Red Hat Enterprise Application Platform (EAP) version 7.4.13. The issue arises from improper handling of the resolve-expression functionality within the HAL (management) interface. A management user with authenticated access can exploit this flaw to read potentially sensitive information from the Wildfly system, which could include configuration details or other internal data not intended for exposure. The vulnerability does not require user interaction but does require management-level privileges, limiting the attack surface to authorized users. The flaw could lead to unauthorized disclosure of sensitive information, potentially aiding further attacks or system compromise. The CVSS v3.1 base score is 6.5, indicating a medium severity, with the vector showing network attack vector, low attack complexity, and privileges required. No public exploits have been reported yet, but the vulnerability is published and should be addressed promptly. The lack of patches at the time of reporting suggests organizations should implement interim mitigations to reduce risk.

For European organizations, the exposure of sensitive information through this vulnerability could lead to increased risk of targeted attacks, especially if attackers gain management credentials through other means. The unauthorized disclosure could facilitate lateral movement, privilege escalation, or data exfiltration in enterprise environments. Organizations relying on Red Hat EAP 7.4.13 for critical business applications, especially in sectors like finance, government, and telecommunications, may face operational risks and compliance issues if sensitive configuration or system data is exposed. The vulnerability does not directly impact availability or confidentiality broadly but compromises integrity by exposing internal system information. Given the requirement for management privileges, the impact is somewhat contained but still significant in environments with weak access controls or exposed management interfaces.

1. Apply official patches from Red Hat as soon as they become available to address CVE-2023-4061 directly. 2. Restrict access to the HAL management interface to trusted networks and users only, using network segmentation and firewall rules. 3. Enforce strong authentication and authorization controls for management users, including multi-factor authentication where possible. 4. Regularly audit management user accounts and privileges to ensure only necessary access is granted. 5. Monitor logs for unusual resolve-expression usage or other suspicious management interface activity. 6. Consider disabling or limiting the resolve-expression functionality if it is not required for operational purposes. 7. Keep the Red Hat EAP environment and underlying systems updated with security patches and best practices.
