CVE-2025-23367 is a medium-severity vulnerability identified in the Wildfly Server's Role Based Access Control (RBAC) provider. The flaw arises because the Suspend and Resume operation handlers fail to verify whether the user has the necessary privileges before allowing these actions. Specifically, users assigned to roles such as Monitor or Auditor, which are intended to have read-only access, can exploit this vulnerability to suspend or resume the server, actions that should be restricted to higher privileged roles. This improper access control undermines the RBAC enforcement mechanism, allowing unauthorized users to disrupt server availability. The vulnerability affects Wildfly versions from 0 up to 28.0.0.Beta1. The CVSS 3.1 base score is 6.5, reflecting a network attack vector, low attack complexity, requiring low privileges but no user interaction, and impacting availability only. Although no known exploits are currently reported in the wild, the vulnerability could be leveraged by attackers to cause denial-of-service conditions by suspending critical server operations. The issue was reserved and published in January 2025, with enrichment from CISA, indicating recognition by US cybersecurity authorities. The lack of authorization checks in critical management operations highlights a significant design oversight in the RBAC implementation of Wildfly's management interface.

The primary impact of CVE-2025-23367 is on the availability of systems running Wildfly servers. Unauthorized users with limited roles can suspend or resume the server, potentially causing service interruptions or denial-of-service conditions. This can disrupt business operations, especially for organizations relying on Wildfly for critical Java application hosting and management. Although confidentiality and integrity are not directly affected, the ability to suspend server operations without proper authorization can lead to operational downtime, loss of productivity, and potential cascading effects on dependent services. In environments with strict uptime requirements or where Wildfly servers manage critical infrastructure, this vulnerability could be exploited to cause significant disruption. The ease of exploitation (network accessible, low privileges required, no user interaction) increases the risk of opportunistic attacks. Organizations lacking proper monitoring or compensating controls may face increased exposure to availability attacks.

To mitigate CVE-2025-23367, organizations should apply any available patches or updates from Wildfly as soon as they are released. In the absence of immediate patches, administrators should restrict access to the Wildfly management interface to trusted users only, using network segmentation, firewalls, or VPNs to limit exposure. Review and tighten RBAC role assignments to ensure that only fully trusted administrators have permissions to suspend or resume the server. Implement monitoring and alerting on management operations to detect unauthorized suspend or resume actions promptly. Consider disabling or restricting the Suspend and Resume operations if they are not required in the environment. Additionally, conduct regular audits of user roles and permissions to prevent privilege escalation or misuse. Employ defense-in-depth strategies such as multi-factor authentication for management access and logging all administrative actions for forensic analysis. Finally, stay informed on vendor advisories and threat intelligence updates related to Wildfly vulnerabilities.
