CVE-2025-53051Network attack vector

SYSDBA disclosure of Functional Index data

Published Oct 21, 2025 · Updated Oct 21, 2025

Information disclosure in Oracle Database 23.4 through 23.9 allows remote authenticated users with SYSDBA to read Functional Index data. Oracle identifies the RDBMS Functional Index component and CISA maps CWE-125, but no public source identifies the operation or input that crosses a buffer boundary. Exploitation requires network access through Oracle Net and the high-privilege SYSDBA role; impact is limited to unauthorized reading of a data subset.
