App - System

Hi !

I managed to get the program to execute my shellcode and spawn a shell but somehow i don’t seem to get the privileges of the running program (so i can’t read the flag).

Do you have any ideas or fix for this problem ?

Thanks you

Same trouble

this is my screen

Look at the other challenges in App - System.
They call the method setreuid before system(’/bin/bash’)

e.g. ELF x86 - Stack buffer overflow basic 2 (ch15)

your shellcode has to do that too
