Vulnerability from variot

A vulnerability in the web interface of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to trigger high CPU usage, resulting in a denial of service (DoS) condition. The vulnerability is due to improper handling of Secure Sockets Layer (SSL) renegotiation requests. An attacker could exploit this vulnerability by sending renegotiation requests at a high rate. An successful exploit could increase the resource usage on the system, eventually leading to a DoS condition. This vulnerability affects version 2.1. An attacker can exploit this issue to cause a denial-of-service condition; denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCvo10487. The platform monitors the network by collecting real-time information on the network, users and devices, and formulating and implementing corresponding policies. There is a resource management error vulnerability in the web interface of Cisco ISE version 2.1, which originates from the improper management of system resources (such as memory, disk space, files, etc.) by network systems or products
