Hint 2: "Tuan Hamba perlu 'dengar', bukan lihat.”

What does it mean by “dengar”? Header? is it not jpeg file? Lets check on it.

Hexeditor Online: https://hexed.it/

After some time searching

fmt - related to wav file. So lets change the header
Header: 52 49 46 8E E3 94 00 57 41 56 45

Now, lets open in Audacity.

Intercept using Burp Suite.

Then we can see it is using base64. try to decode to confirm.

decode base64 shows the page name.

So now i try encode ../../../../../etc/passwd

Put it in cookie.

Successfully read.

Now, I tried to read php file. But I will use PHP filter php://

After some guessing, we got the right path.

flag=((3108,"{",p,q,b,p,l,g,l,q,l,v,"_",d,g,h,s,v,k,"_",l,v,m,l,"}")[::-1])

I add print to print the output.

# Variable assignments
a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z = \\
    'j', 'b', 'a', 'c', 'm', 'n', 'i', 'p', 'o', 'q', 'r', 't', 'x', 'z', 'v', 's', 'u', 'y', 'h', 'g', 'd', 'e', 'f', 'k', 'l', 'w'

# Create the flag tuple and reverse it
flag = ((3108, "{", p, q, b, p, l, g, l, q, l, v, "_", d, g, h, s, v, k, "_", l, v, m, l, "}")[::-1])

# Convert the reversed tuple to a string and print it
flag_str = ''.join(map(str, flag))
print(flag_str)

But the result seems to backwards.

So, i mend to not output in backwards

# Variable assignments
a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z = \\

# Create the flag tuple without reversing
flag = (3108, "{", p, q, b, p, l, g, l, q, l, v, "_", d, g, h, s, v, k, "_", l, v, m, l, "}")

# Convert the tuple to a string and print it
flag_str = ''.join(map(str, flag))
print(flag_str)
