Authenticated table disclosure via indirect unauthorized reads
Published Dec 9, 2021 · Updated Sep 17, 2024
Information disclosure in IBM Db2 11.1 and 11.5 allows remote authenticated users to read table data indirectly without SELECT authority. Db2 permits an indirect table-read path to return data even when the connected account lacks SELECT authority on the table. Exploitation requires a valid database connection and exposes only data reached through the unauthorized indirect read.
