CVE-2022-39402

Unauthorized read access to Shell data

Published Oct 18, 2022 · Updated Sep 24, 2024

Information disclosure in Oracle MySQL Shell 8.0.30 and earlier allows unauthenticated attackers with local logon to read accessible data. The affected Shell Core Client operation is not disclosed in Oracle or NVD records, so the precise untrusted-input locus remains unpublished. Exploitation requires logon to the infrastructure hosting Shell and is limited to unauthorized read access to a subset of data, with no integrity or availability impact reported.
