CWE-834

Excessive Iteration
AI Translation Available

The product performs an iteration or loop without sufficiently limiting the number of times that the loop is executed.

Status
incomplete
Abstraction
class

If the iteration can be influenced by an attacker, this weakness could allow attackers to consume excessive resources such as CPU or memory. In many cases, a loop does not need to be infinite in order to cause enough resource consumption to adversely affect the product or its host system; it depends on the amount of resources consumed per iteration.

Common Consequences

availability
Impacts
dos: resource consumption (cpu) dos: resource consumption (memory) dos: amplification dos: crash, exit, or restart

Detection Methods

dynamic analysis with manual results interpretation manual static analysis - source code automated static analysis - source code architecture or design review
