CVE-2022-22353Network attack vector

Sensitive-data disclosure via masking-rule bypass

Published Mar 14, 2022 · Updated Sep 16, 2024

Information disclosure in IBM Db2 Big SQL 7.1.0, 7.1.1, 7.2.0, and 7.2.3 allows remote authenticated users to read masked data. The CREATE TABLE SELECT processing path materializes query results without enforcing data-masking rules on protected source columns. A database account with permission to issue the statement and select protected data can copy unmasked values into a new table; no integrity or availability impact is reported.
