CVE-2026-83417

Published Sep 15, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
Vulnerability in the Oracle Communications Cloud Native Core Security Edge Protection Proxy product of Oracle Communications (component: SEPP). Supported versions that are affected are 26.1.200 and 25.2.201. Easily exploitable vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Communications Cloud Native Core Security Edge Protection Proxy executes to compromise Oracle Communications Cloud Native Core Security Edge Protection Proxy. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Communications Cloud Native Core Security Edge Protection Proxy accessible data as well as unauthorized update, insert or delete access to some of Oracle Communications Cloud Native Core Security Edge Protection Proxy accessible data. CVSS 3.1 Base Score 7.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N).

Analysis

Technical impact

Vulnerability in the Oracle Communications Cloud Native Core Security Edge Protection Proxy allows an attacker who has physical access to the communication segment connected to the hardware to bypass authentication and gain unauthorized access to the proxy. Successful exploitation can lead to reading critical data with high confidentiality impact and modifying or deleting data, producing integrity impact. The vulnerability appears to involve an access control issue, inferred from the fact that users without credentials can interact with protected resources.

Affected Systems

Oracle Communications Cloud Native Core Security Edge Protection Proxy versions 26.1.200 and 25.2.201.

Risk and Exploitability

The CVSS 3.1 Base Score of 7.1 indicates a high severity risk. The EPSS score of less than 1% reflects a low current exploitation probability. The vulnerability is not listed in CISA’s KEV catalog. Because the attack vector requires physical access to the communication segment attached to the hardware where the SEPP runs, the attacker does not need remote network interaction; physical connectivity alone is sufficient to exploit an access control weakness, inferred from the description indicating unauthenticated interaction.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Oracle Communications Cloud Native Core Security Edge Protection Proxy to a patched version that addresses the access control flaw.
  • Restrict physical access to the hardware segments that host SEPP and implement network segmentation to isolate the proxy from untrusted traffic.
  • Implement monitoring of proxy access logs to detect attempted unauthenticated interactions.
