WebJan 5, 2024 · Exploitation. The first step in exploiting this type of vulnerability is to understand how to decrypt the encrypted text using the key and IV available. One way is to write our own decryptor, which is prone to errors. Another way is to understand the decryption logic used by the application and use the same logic to write our decryptor. In cryptography, a one-way compression function is a function that transforms two fixed-length inputs into a fixed-length output. The transformation is "one-way", meaning that it is difficult given a particular output to compute inputs which compress to that output. One-way compression functions are not related to conventional data compression algorithms, which instead can be inverted ex…
