CVE-2020-2766Network attack vector

Unauthenticated disclosure of server-accessible data

Published Apr 15, 2020 · Updated Sep 30, 2024

Information disclosure in Oracle WebLogic Server Console 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, and 12.2.1.4.0 allows remote attackers to read data. Oracle has not published the affected request path or the Console operation that improperly discloses data, so the implementation-level mechanism is undisclosed. Unauthenticated network access over HTTP is sufficient, and the reported consequence is limited to reading a subset of WebLogic Server-accessible data.
