Joining a table based on comma separated values mysql

I have a table [CourseMaster] LIKE

CourseId    CourseName
-----------------------
  01          ABC
  02          DEF
  03          GHI
  04          JKL
  05          MNO
  06          PQR
  07          STU

And I have another table [StudentMaster] for Student Details LIKE

ROLLNO  NAME    ADDRESS          Course
------------------------------------------------
12345   RAM     RAM ADDRESS      01,02,06                      
25695   HARI    HARI ADDRESS     02,06                         
89685   JEFF    JEFF ADDRESS     03,05,06,07                   
47896   DAISY   DAISY ADDRESS    03         

I want result like this

ROLLNO  NAME    ADDRESS         Course
-------------------------------------------
12345   RAM     RAM ADDRESS     ABC,DEF,PQR
