The application typically uses . In CBC mode, each block of ciphertext is XORed with the next block's plaintext during decryption. This structure allows an attacker to manipulate one block to "guess" the plaintext of the next block byte-by-byte. 3. Automate the Attack
Now that you can decrypt existing pastebins (via the Oracle) and forge valid ciphertexts (via Bit-Flipping or CBC block construction), you can inject custom payloads into the system. hacker101 encrypted pastebin
