A flaw was found in the Wildfly Server Role Based Access Control (RBAC) provider. When authorization to control management operations is secured using the Role Based Access Control provider, a user without the required privileges can suspend or resume the server. A user with a Monitor or Auditor role is supposed to have only read access permissions and should not be able to suspend the server. The vulnerability is caused by the Suspend and Resume handlers not performing authorization checks to validate whether the current user has the required permissions to proceed with the action.
This vulnerability allows unauthorized users to disrupt the availability of the Wildfly server, leading to potential service outages. Given its medium severity with a CVSS score of 6.5, organizations must prioritize remediation efforts to prevent misuse.
Risk to organizations includes the possibility of unauthorized access leading to server suspension or resumption, which can have significant operational impacts. Organizations should prioritize patching immediately.
Currently, there are no known exploits associated with this vulnerability, but the potential for exploitation exists. Organizations should stay vigilant for any signs of unauthorized access attempts.
Vulnerability Details
The vulnerability description indicates a serious flaw in the authorization checks of the Wildfly Server RBAC provider. The CVSS score of 6.5 categorizes this as a medium severity issue, primarily affecting the availability of the server.
Published on January 30, 2025, this vulnerability affects the RedHat Wildfly and JBoss Enterprise Application Platform components. The lack of proper authorization checks for the Suspend and Resume handlers can lead to unauthorized server control.
The vulnerability is classified under CWE-284, indicating improper access control, which is a significant concern for organizations relying on these technologies.
Technical Analysis
The root cause of this vulnerability lies in the inadequate authorization checks within the Suspend and Resume handlers of the Wildfly Server. Attackers may leverage this weakness to gain unauthorized control over server management operations.
The attack vector is network-based, which means an attacker can exploit this vulnerability remotely. With low attack complexity and requiring low privileges, the risk of exploitation increases significantly.
No user interaction is required for exploitation, making it easier for an attacker to carry out an attack without alerting the target. The impact on availability is high, as unauthorized users could suspend critical services.
Risk & Impact Analysis
The deployment of the Wildfly Server in production environments poses a real-world risk due to this vulnerability. Organizations running affected versions of Wildfly or JBoss Enterprise Application Platform should assess their exposure and take immediate action.
The blast radius potential is significant, as an attacker gaining control over server management can lead to service disruptions or data integrity issues. Given that the CVSS score indicates medium severity, organizations should address in priority patch cycle.
Organizations must evaluate their security posture regarding the Wildfly Server and implement necessary mitigations to prevent unauthorized actions. The potential for exploitation, despite no known exploits, should not be overlooked.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions include JBoss Enterprise Application Platform versions from 7.4 to 7.4.20 and 8.0.0 to 8.0.6, as well as Wildfly versions up to 27.0.1 and the beta version of 28.0.0.
Mitigation & Remediation
Organizations should upgrade to the latest versions of the affected products to ensure they are protected from this vulnerability. For JBoss Enterprise Application Platform, upgrading to version 7.4.21 or later, and for Wildfly, upgrading to 28.0.1 or later is recommended.
If a patch is not available, consider implementing configuration hardening to limit access to management operations and monitor for any unauthorized actions within the server.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual access patterns related to management operations. Behavioral anomalies, such as unexpected server suspensions or resumes by users with restricted roles, should be flagged for further investigation.
AppSecure Threat Intelligence Insight
This vulnerability highlights a critical area of concern in role-based access controls within server management. Security teams must ensure that proper authorization checks are in place to mitigate similar weaknesses in the future. For strategic insights, organizations can refer to the penetration testing methodology to enhance their security posture.
Furthermore, organizations should consider integrating continuous security assessments into their operational frameworks. This can be complemented by reviewing best practices in vulnerability management programs to proactively address the emerging threats.
In summary, the insights gained from this vulnerability can serve as a learning opportunity for security teams, emphasizing the importance of rigorous access controls and regular assessments.
