CWE-617: Reachable Assertion
Weakness ID : 617
Structure : Simple
Abstraction : Base
Description
The product contains an assert() or similar statement that can be triggered by an attacker, which
leads to an application exit or other behavior that is more severe than necessary.
Extended Description
While assertion is good for catching logic errors and reducing the chances of reaching more
serious vulnerability conditions, it can still lead to a denial of service.
For example, if a server handles multiple simultaneous connections, and an assert() occurs in one
single connection that causes all other connections to be dropped, this is a reachable assertion that
leads to a denial of service.
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.
