Insufficient Resource Pool
The software's resource pool is not large enough to handle peak demand, which allows an attacker to prevent others from accessing the resource by using a (relatively) large number of requests for resources.
Frequently the consequence is a "flood" of connection or sessions.
The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.
Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.
In the following snippet from a Tomcat configuration file, a JDBC connection pool is defined with a maximum of 5 simultaneous connections (with a 60 second timeout). In this case, it may be trivial for an attacker to instigate a denial of service (DoS) by using up all of the available connections in the pool.
