SELECT * FROM dbo.Ex

You can use Dynamic SQL:

LiveDemo

-- sample data
CREATE TABLE #Example(ID INT IDENTITY(1,1), Rights VARCHAR(100));
INSERT INTO #Example VALUES ('ASD'), ('ABC'), ('IOP');


DECLARE @Rights NVARCHAR(MAX) = 'ASD,ZXC,QWE,IOP,JKL';
DECLARE @sql NVARCHAR(MAX) = 
  N'SELECT * 
   FROM #Example
   WHERE Rights IN ('''')';

SET @sql = REPLACE(@sql, '', REPLACE(@Rights, ',', ''','''));

-- SELECT @sql; -- for debug

EXEC dbo.sp_executesql
    @sql;

But you should reconsider using Table Valued Parameter instead.
