Vulnerability in the Oracle Communications Diameter Signaling Router (DSR) component of Oracle Communications Applications (subcomponent: Security). The supported version that is affected is prior to 8.3. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Communications Diameter Signaling Router (DSR). Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Communications Diameter Signaling Router (DSR) accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Communications Diameter Signaling Router (DSR). CVSS 3.0 Base Score 6.5 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L).

Security readout for executives and security teams

CVE-2019-2399 affects Oracle Communications Diameter Signaling Router before 8.3. An unauthenticated attacker who can reach the service over HTTP may read some accessible data and trigger partial service disruption. The impact is meaningful for telecom environments, but the source bundle does not show active exploitation. Exposure is likely limited to organizations running Oracle Communications DSR versions prior to 8.3, especially where HTTP access is reachable from untrusted networks. The sources do not identify specific configurations, endpoints, or exposure prevalence. Prioritize remediation for telecom or signaling environments where DSR HTTP interfaces are exposed beyond tightly controlled networks. Business risk is data exposure plus partial service degradation, not full system takeover based on the supplied evidence. Mitigation focus: Upgrade Oracle Communications DSR to version 8.3 or later if applicable.; Review Oracle CPU January 2019 guidance for the supported remediation path.; Restrict HTTP access to trusted management or operational networks..
