Title

ColdFusion must limit the maximum number of simultaneous Report threads. (Cat II impact)

Discussion

DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. To reduce the possibility or effect of a DoS, the application server must employ defined security safeguards. These safeguards will be determined by the placement of the application server and the type of applications being hosted within the application server framework. Report threads are used to process reports concurrently. Since reporting in most applications is a process that is not time sensitive or heavily used, this setting should be minimized to minimize resource use on the application server and to minimize a method that could be used to exhaust resources by an attacker. Unless reporting is heavily used, the number of simultaneous report threads must be set to 1.
