CVE-2026-15563
HighCVSS 7.4Exploitation Probability (EPSS)
Elevated risk52th percentile - higher than 52% of all known CVEs
Summary
In EAP IIOP, the NameService accepts bind operations without authentication, allowing an attacker to hijack JNDI lookups and bind them to a malicious ORB, achieving MITM or DoS on further invocations.
Risk Assessment
Risk of communication interception and disruption of services using JNDI, potentially leading to data leakage or system unavailability.
Recommendation
Enable authentication for bind operations in NameService and restrict access to IIOP ports to trusted clients only.
