CVE-2026-15563: Missing Authentication for Critical Function in Red Hat Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7
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.
AI Analysis
Technical Summary
A missing authentication flaw in the IIOP listener's NameService component of Red Hat JBoss Enterprise Application Platform 7 allows unauthenticated bind operations. This enables attackers to hijack JNDI lookups and redirect them to malicious ORBs, facilitating man-in-the-middle or denial of service attacks on further invocations. The vulnerability is tracked as CVE-2026-15563 with a CVSS v3.1 base score of 7.4 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N). The Red Hat advisory confirms the issue but does not specify affected versions or patch availability. The flaw is classified under CWE-306 (Missing Authentication for Critical Function).
Potential Impact
Successful exploitation can lead to high confidentiality and integrity impacts by allowing attackers to intercept or manipulate JNDI lookups, potentially compromising sensitive data or application behavior. Availability impact is not affected. The vulnerability requires network access and high attack complexity, with no privileges or user interaction needed.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-15563 for current remediation guidance. No official fix or temporary workaround is explicitly stated in the advisory. Users should monitor the vendor advisory for updates and apply patches or mitigations once available.
