从根本上解决网页注入漏洞被挂马(正确配置mssql数据库用户权限)

 1.无论如何不能使用sa直接连接，建议新建一个public权限数据库用户，并用这个用户作为连接数据库

2.去掉public对sysobject与syscolumns的select访问
3.通过以下代码检测（失败表示权限正确）：
DECLARE @T varchar(255), @C varchar(255) DECLARE Table_Cursor CURSOR FOR Select a.name,b.name from sysobjects a, syscolumns b where a.id=b.id and a.xtype='u' and (b.xtype=99 or b.xtype=35 or b.xtype=231 or b.xtype=167) OPEN Table_Cursor FETCH NEXT FROM Table_Cursor INTO @T,@C WHILE(@@FETCH_STATUS=0) BEGIN print 'a' FETCH NEXT FROM Table_Cursor INTO @T,@C END CLOSE Table_Cursor DEALLOCATE Table_Cursor
