CVE-2021-2079Network attack vector

Unauthenticated data access and modification via UI Servlet

Published Jan 20, 2021 · Updated Sep 26, 2024

An undisclosed flaw in Oracle Configurator 12.1 and 12.2 allows remote attackers to read and modify data through the UI Servlet. Oracle has not published the faulty request handling or input-processing operation within the servlet, so the exact mechanism is undisclosed. Exploitation requires no authentication but does require interaction by a person other than the attacker; all Configurator-accessible data can be read, and some data can be inserted, updated, or deleted.
