CVE-2020-2890Network attack vector

Unauthenticated data access and modification

Published Apr 15, 2020 · Updated Sep 27, 2024

An undisclosed flaw in Oracle Applications Framework Diagnostics 12.1.3 and 12.2.3 through 12.2.9 allows remote attackers to read or alter data via HTTP. Oracle has not published the flawed request handler, input, or operation within Diagnostics, so the concrete mechanism remains undisclosed. Exploitation requires no authentication but does require another person to interact, and it can expose all framework-accessible data or modify some of it.
