There are special cases when injection point is within the URI itself. sqlmap does not perform any automatic test against URI paths, unless manually pointed to. You have to specify these injection points in the command line by appending an asterisk (*) (Note: Havij style %INJECT HERE% is also supported) after each URI point that you want sqlmap to test for and exploit a SQL injection.
