CVE-2026-46495
OpenDJ Pre-Auth RCE via Java Deserialization in JMX RMI
Severidad por fuente
La etiqueta propia de Trivy es CRITICAL. Crítica según GHSA.
Descripción
OpenDJ is an LDAPv3 compliant directory service. Prior to 5.1.1, the JMX RMI connector in opendj-server-legacy/src/main/java/org/opends/server/protocols/jmx/RmiConnector.java processes attacker-controlled credential objects before authentication without a restrictive jmx.remote.rmi.server.credentials.filter.pattern, and RmiAuthenticator.authenticate in opendj-server-legacy/src/main/java/org/opends/server/protocols/jmx/RmiAuthenticator.java accepts an unconstrained Object array rather than a two-element String[]. When the JMX Connection Handler is enabled and its TCP listener is reachable, an unauthenticated remote attacker can submit a crafted serialized Java object and achieve code execution in the OpenDJ server process. The handler is disabled by default, and successful exploitation depends on the runtime classpath and Java version; remote code execution was demonstrated against OpenDJ 4.4.15 on JDK 11 with Jackson 2.12.6.1. This issue is fixed in 5.1.1.
