'Name' => 'Bomberclone 0.11.6 Buffer Overflow',
|
|
'Description' => %q{
|
|
This module exploits a stack buffer overflow in Bomberclone 0.11.6 for Windows.
|
|
The return address is overwritten with lstrcpyA memory address,
|
|
the second and third value are the destination buffer,
|
|
the fourth value is the source address of our buffer in the stack.
|
|
This exploit is like a return in libc.
|
|
|
|
ATTENTION
|
|
The shellcode is exec ONLY when someone try to close bomberclone.
