The table(s) below shows the other attack patterns and high level categories that are related to this attack pattern. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as CanFollow, PeerOf, and CanAlsoBe are defined to show similar attack patterns that the user may want to explore.
Relevant to the view "Mechanisms of Attack" (CAPEC-1000)
Standard Attack Pattern - A standard level attack pattern in CAPEC is focused on a specific methodology or technique used in an attack. It is often seen as a singular piece of a fully executed attack. A standard attack pattern is meant to provide sufficient details to understand the specific technique and how it attempts to accomplish a desired goal. A standard level attack pattern is a specific type of a more abstract meta level attack pattern.
The decryption routine does not properly authenticate the message / does not verify its integrity prior to performing the decryption operation
The target system leaks data (in some way) on whether a padding error has occurred when attempting to decrypt the ciphertext.
The padding oracle remains available for enough time / for as many requests as needed for the adversary to decrypt the ciphertext.
Ability to detect instances where a target system is vulnerable to an oracle padding attack Sufficient cryptography knowledge and tools needed to take advantage of the presence of the padding oracle to perform decryption / encryption of data without a key
Design: Use a message authentication code (MAC) or another mechanism to perform verification of message authenticity / integrity prior to decryption
Implementation: Do not leak information back to the user as to any cryptography (e.g., padding) encountered during decryption.
