A vulnerability classified as critical was found in Oracle Communications Diameter Signaling Router up to 8.2.2 (Cloud Software). Affected by this vulnerability is an unknown code block of the component IDIH. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. As an impact it is known to affect confidentiality. The summary by CVE is:

Apache CXF has the ability to integrate with JMX by registering an InstrumentationManager extension with the CXF bus. If the ‘createMBServerConnectorFactory‘ property of the default InstrumentationManagerImpl is not disabled, then it is vulnerable to a man-in-the-middle (MITM) style attack. An attacker on the same host can connect to the registry and rebind the entry to another server, thus acting as a proxy to the original. They are then able to gain access to all of the information that is sent and received over JMX.

The weakness was presented 10/20/2020 as Oracle Critical Patch Update Advisory - October 2020. It is possible to read the advisory at oracle.com. This vulnerability is known as CVE-2020-1954 since 12/02/2019. The exploitation appears to be difficult. Access to the local network is required for this attack.
