-- This file tries to find stored procedures and functions that *may* be vulnerable to SQL injection attacks. | |
-- It works by searching your database for occurences of "+" signs followed by "@", indicating that SQL parameters | |
-- might be getting concatenated to a dynamic SQL string. It also checks for the existence of 'EXEC' to see if any | |
-- strings are being executed. | |
-- Not every result returned will be susceptible to SQL injection, however they should all be examined to see if they are vulnerable. | |
