AnalysisAI

Improper authentication in the Personalization component of Oracle Applications Framework (Oracle E-Business Suite 12.2.3 through 12.2.15) lets an unauthenticated remote attacker reach the SOAP interface and take over the framework, with full confidentiality, integrity and availability impact (CVSS 3.1 base 9.8, AV:N/AC:L/PR:N/UI:N). CISA's SSVC assessment rates the technical impact as total and the vulnerability as automatable, meaning exploitation could be scripted and scaled once a target is reachable. …
