A vulnerability was found in Wildfly's Enterprise Java Beans (EJB) versions shipped with Red Hat JBoss EAP 7, where SessionOpenInvocations are never removed from the remote InvocationTracker after a response is received in the EJB Client, as well as the server. This flaw allows an attacker to craft a denial of service attack to make the service unavailable.

The remote Redhat Enterprise Linux 6 / 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:3817 advisory.

  - log4j: improper validation of certificate with host mismatch in SMTP appender (CVE-2020-9488)

  - jackson-databind: Serialization gadgets in org.apache.openjpa.ee.WASRegistryManagedRuntime     (CVE-2020-11113)

  - wildfly: Some EJB transaction objects may get accumulated causing Denial of Service (CVE-2020-14297)

  - wildfly: EJB SessionOpenInvocations may not be removed properly after a response is received causing     Denial of Service (CVE-2020-14307)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
