CVE-2026-83345

Oracle XML Gateway Uncontrolled Resource Consumption Vulnerability

Published Sep 15, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle XML Gateway product of Oracle E-Business Suite (component: Install). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle XML Gateway. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle XML Gateway accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle XML Gateway. CVSS 3.1 Base Score 7.1 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:L).

Analysis

Technical impact

The vulnerability resides in the Install component of Oracle XML Gateway, part of Oracle E‑Business Suite, and permits an attacker with low‑privileged access and network connectivity over HTTP to bypass normal controls. Successful exploitation allows reading any data that the gateway can reach and can trigger a partial denial of service. The weakness involves insufficient validation and safeguarding of resources during request processing.

Affected Systems

Oracle XML Gateway in Oracle E‑Business Suite versions 12.2.3 through 12.2.15, deployed as the Install component within the suite.

Risk and Exploitability

The CVSS Base Score of 7.1 indicates moderate‑to‑high severity, while the EPSS score of less than 1% suggests an extremely low likelihood of exploitation at present. The vulnerability is not listed in CISA’s KEV catalog. Exploitation requires only low‑privilege credentials and network access over HTTP to the gateway; no additional prerequisites or privileged escalation steps are necessary.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Apply the latest Oracle patch that addresses the XML Gateway vulnerability or upgrade beyond the 12.2.15 release.
If a patch or upgrade is not immediately available, restrict external HTTP traffic to trusted IP addresses and enforce authentication before permitting access.
Monitor gateway logs for abnormal access patterns and configure firewall or network segmentation rules to isolate the gateway and limit potential impact.
