WebAug 3, 2024 · BabyRust We were asked to pwn a rust program. Since the program is kind of complicated, lots of stuff were done by fuzzing/trial and error. Vulnerability With some fuzzing, we quickly found that we were able to leak the heap address by using the following payload: magic (1312) # send "1312" command show () # leak heap base Webcrypto Message intercepted. Break it. babyrsa.zip We are given the encryption (with no padding) of a short message with a 4096-bit RSA key with e = 5 . Recall that RSA encrypts with c = me mod n . Because m is short and e is small, me < n . Because it never wraps around, we can take the fifth root as in normal arithmetic.
