While manual bit-flipping verifies the bug, automated tools make exploitation practical. PadBuster is a highly effective command-line script designed to automate padding oracle attacks. padbuster http://35

The fatal flaw in the Encrypted Pastebin architecture is that it encrypts data but does not sign it. It lacks a , such as an HMAC. Without a MAC, the server cannot verify if the ciphertext was altered after creation. The Bit-Flipping Strategy In CBC mode, changing a byte in block completely scrambles block
