Authenticated data disclosure and partial service disruption

Published Oct 20, 2021 · Updated Sep 25, 2024

Information disclosure and denial of service in Oracle Secure Global Desktop 5.6 allow remote authenticated users to read data and disrupt service. Oracle identifies the affected locus only as the Server component and has not published the operation that mishandles untrusted input. Exploitation requires low-privileged network access over one of multiple supported protocols and is bounded to subset data disclosure and partial service interruption.
