CVE-2026-15563 in WildFly
Summary
by MITRE • 08/11/2026
A flaw was found in EAP's IIOP. The listener's NameService would accept bind operations without authentication, allowing an attacker to hijack JNDI lookups and binding them to a malicious ORB, achieving MITM or DoS on further invocations.

This vulnerability resides within the Enterprise Application Platform's Internet Inter-ORB Protocol implementation where the NameService listener demonstrates a critical security flaw that violates fundamental authentication principles. The issue manifests as an insufficient authorization mechanism that permits any remote entity to perform bind operations against the naming service without requiring proper authentication credentials. This weakness creates a pathway for malicious actors to manipulate the JNDI lookup process by hijacking existing bindings and redirecting them to attacker-controlled Object Request Brokers. The vulnerability directly corresponds to CWE-287 which addresses improper authentication scenarios, and aligns with ATT&CK technique T1566 related to credential harvesting through service manipulation.
The technical exploitation of this flaw enables attackers to establish unauthorized bindings within the CORBA naming context, effectively allowing them to intercept and redirect subsequent JNDI lookups that would normally resolve to legitimate services. When applications attempt to perform JNDI operations, they encounter the attacker-controlled bindings instead of the intended targets, creating opportunities for man-in-the-middle attacks where network traffic can be intercepted, modified, or redirected. The impact extends beyond simple interception as attackers can also cause denial-of-service conditions by binding names to non-existent or invalid ORB endpoints, thereby breaking legitimate application functionality.
The operational consequences of this vulnerability are severe given that CORBA NameService implementations typically serve as critical infrastructure components for service discovery and object location within distributed enterprise applications. Applications relying on JNDI lookups for resource resolution become vulnerable to arbitrary redirection attacks that can compromise entire service chains. The lack of authentication checks means that even unprivileged network entities can manipulate the naming service, potentially affecting multiple applications that depend on the same CORBA infrastructure. This vulnerability essentially provides attackers with a persistent foothold within the CORBA domain that can be leveraged for further exploitation.
Mitigation strategies should focus on implementing robust authentication mechanisms for all NameService operations including bind, rebind, and unbind functions. The system should enforce mandatory authentication before allowing any naming service modifications and implement proper access control lists to restrict which entities can perform binding operations. Network segmentation and firewall rules should be implemented to limit access to the CORBA naming service ports to only authorized administrative systems. Additionally, organizations should consider implementing monitoring solutions that can detect unusual binding patterns or unauthorized modifications to the naming context, as these activities would typically indicate exploitation attempts. The fix should align with security best practices outlined in NIST SP 800-53 and ISO/IEC 27001 controls related to access control and authentication management.
