CWE-206: Observable Internal Behavioral Discrepancy
Weakness ID : 206
Structure : Simple
Abstraction : Variant
Description
The product performs multiple behaviors that are combined to produce a single result, but the
individual behaviors are observable separately in a way that allows attackers to reveal internal state
or internal decision points.
Extended Description
Ideally, a product should provide as little information as possible to an attacker. Any hints that
the attacker may be making progress can then be used to simplify or optimize the attack. For
example, in a login procedure that requires a username and password, ultimately there is only one
decision: success or failure. However, internally, two separate actions are performed: determining
if the username exists, and checking if the password is correct. If the product behaves differently
based on whether the username exists or not, then the attacker only needs to concentrate on the
password.
Relationships
The table(s) below shows the weaknesses and high level categories that are related to this
weakness. These relationships are defined as ChildOf, ParentOf, MemberOr and give insight to
similar items that may exist at higher and lower levels of abstraction. In addition, relationships such
as PeerOf and CanAlsoBe are defined to show similar weaknesses that may want to be explored.
