AnalysisAI

Unauthenticated TCP network access to the Oracle Mobile Application Server component (MWA Terminal Server) in Oracle E-Business Suite 12.2.3 through 12.2.15 lets an attacker bypass authentication details and gain unrestricted read access to data reachable by that service while also degrading its availability. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N, C:H/I:N/A:L, base 8.2) confirms no credentials or victim interaction are needed, making exploitation trivially automatable once the middle-tier service is reachable. …
