Vulnerability in the Oracle Reports Developer product of Oracle Fusion Middleware (component: Security and Authentication). The supported version that is affected is 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with access to the physical communication segment attached to the hardware where the Oracle Reports Developer executes to compromise Oracle Reports Developer. While the vulnerability is in Oracle Reports Developer, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Reports Developer accessible data as well as unauthorized access to critical data or complete access to all Oracle Reports Developer accessible data. CVSS 3.1 Base Score 9.3 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N).
AnalysisAI
Oracle Reports Developer 14.1.2.0.0 exposes an unauthenticated authentication bypass in its Security and Authentication component, allowing an attacker on the same physical network segment to fully compromise confidentiality and integrity of all accessible data - including critical data - without any credentials or user interaction. The vulnerability carries a scope change, meaning successful exploitation may cascade to impact additional Oracle Fusion Middleware products beyond Reports Developer itself. …
