CVE-2025-23368 identifies a security weakness in the Wildfly Elytron integration component, specifically its failure to adequately restrict excessive authentication attempts via the command-line interface (CLI). Wildfly Elytron is a security framework used in Java EE application servers to provide authentication and authorization services. The vulnerability arises because the component does not implement sufficient controls such as rate limiting, account lockouts, or progressive delays after multiple failed login attempts. This deficiency allows an attacker to perform brute force attacks by repeatedly trying different credentials in rapid succession without being blocked or slowed down. The CVSS 3.1 base score of 8.1 indicates a high severity, with the vector showing network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although exploitation requires network access to the CLI interface, no authentication or user interaction is needed, making it a significant risk if the CLI is exposed or accessible internally. The vulnerability could lead to unauthorized access, data breaches, system manipulation, or denial of service if attackers successfully guess valid credentials. Currently, there are no known exploits in the wild, and no patch links are provided, indicating that remediation may still be pending or in progress. Organizations using Wildfly Elytron should prioritize addressing this issue due to its potential impact on critical enterprise applications.

For European organizations, this vulnerability poses a substantial risk to the security of enterprise Java applications relying on Wildfly Elytron for authentication. Successful exploitation can lead to unauthorized access to sensitive data, disruption of services, and potential lateral movement within networks. Industries such as finance, government, telecommunications, and critical infrastructure that deploy Wildfly-based applications are particularly vulnerable. The ability to perform brute force attacks without effective throttling increases the likelihood of credential compromise, especially if weak or reused passwords are in use. This can result in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and operational downtime. The high impact on confidentiality, integrity, and availability underscores the critical nature of this vulnerability in environments where Wildfly Elytron is deployed. Additionally, the CLI interface is often used for administrative tasks, so compromise could lead to full system control by attackers.

To mitigate CVE-2025-23368, organizations should implement the following specific measures: 1) Apply any available patches or updates from Wildfly or Red Hat as soon as they are released. 2) Restrict network access to the CLI interface using firewalls, VPNs, or network segmentation to limit exposure to trusted administrators only. 3) Implement rate limiting or throttling mechanisms on authentication attempts to prevent rapid brute force attacks. 4) Enforce strong password policies and consider multi-factor authentication (MFA) for CLI access to reduce the risk of credential compromise. 5) Monitor authentication logs for repeated failed login attempts and configure alerts for suspicious activity. 6) Consider deploying Web Application Firewalls (WAFs) or Intrusion Detection/Prevention Systems (IDS/IPS) that can detect and block brute force patterns. 7) Conduct regular security assessments and penetration testing focused on authentication mechanisms. 8) Educate administrators on secure usage of CLI and the importance of safeguarding credentials. These steps go beyond generic advice by focusing on access control, monitoring, and layered defenses specific to the Wildfly Elytron context.
