Description
The vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists due to Db2's Row and Column Access Control (RCAC) rules are not being enforced when creating a table using AS (CTAS) sub-select statements. A local attacker can create a table using AS (CTAS) sub-select statements to bypass Row and Column Access Control (RCAC) rules when using the 'WITH DATA' clause to select and insert data, allowing a user to bypass FGAC access controls and gain access important data.
