Vulnerability in the Oracle BI Publisher product of Oracle Analytics (component: BI Platform Security). Supported versions that are affected are 8.2.0.0.0, 12.2.1.4.0 and 26.1.0.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle BI Publisher. While the vulnerability is in Oracle BI Publisher, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle BI Publisher accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle BI Publisher. CVSS 3.1 Base Score 8.5 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L).
AnalysisAI
Oracle BI Publisher's BI Platform Security component exposes high-severity data access and partial denial-of-service risk to low-privileged, network-based attackers across three actively supported versions (8.2.0.0.0, 12.2.1.4.0, and 26.1.0.0.0). The 'Authentication Bypass' tag, combined with CVSS PR:L and S:C, indicates that a minimally authenticated attacker can circumvent platform-level security controls to gain complete unauthorized read access to all data accessible by BI Publisher and partially disrupt service - with confirmed scope change meaning downstream Oracle product integrations may also be compromised. …
