CWE-834
Excessive Iteration
Description
The product performs an iteration or loop without sufficiently limiting the number of times that the loop is executed.
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.
