Lateral SQL Injection

David Litchfield · NGSSoftware

Shows how Oracle session settings can influence supposedly safe DATE values embedded in dynamic SQL. Changing NLS_DATE_FORMAT introduces SQL through date parameters or SYSDATE, reaching procedures with no direct user input and enabling privilege escalation with cursor injection. It also demonstrates quote insertion through numeric formatting, while limiting claims about its exploitability.
