High-privilege limited data disclosure

Published Jan 20, 2021 · Updated Sep 26, 2024

Information disclosure in Oracle WebLogic Server 10.3.6.0.0 and 12.1.3.0.0 allows remote authenticated users to read limited data over HTTP. Oracle has not disclosed the faulty operation on untrusted input within the Web Services component. Exploitation requires high privileges and interaction by another person, and the documented consequence is limited to reading a subset of accessible server data.
