2DescriptionCVE.org
Vulnerability in the Oracle WebCenter Portal product of Oracle Fusion Middleware (component: Composer). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Difficult to exploit vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle WebCenter Portal. While the vulnerability is in Oracle WebCenter Portal, 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 WebCenter Portal accessible data as well as unauthorized read access to a subset of Oracle WebCenter Portal accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle WebCenter Portal. CVSS 3.1 Base Score 7.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:H/A:L).
AnalysisAI
Compromise of Oracle WebCenter Portal's Composer component - versions 12.2.1.4.0 and 14.1.2.0.0 - allows an authenticated low-privilege attacker over HTTP to achieve high-integrity impact, including unauthorized creation, deletion, and modification of critical portal data, limited confidentiality exposure, and partial denial of service. The CVSS scope change (S:C) indicates exploitation can cascade to additional Oracle Fusion Middleware products beyond WebCenter Portal itself. …
