Published: Translated: NVD NIST

Summary

A vulnerability in the TCP throttling process for the GUI of Cisco Identity Services Engine (ISE) 2.1(0.474) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The issue is due to insufficient TCP rate limiting protection on the GUI.

Risk Assessment

The organization may experience downtime of the GUI, leading to disruptions in identity and access management. An attacker could exploit this vulnerability to overwhelm the system, resulting in the GUI failing to respond.

Recommendation

It is recommended to update Cisco ISE to the latest version that includes security patches. Additionally, implementing TCP rate limiting mechanisms can help minimize the risk of DoS attacks.

Original NVD description (English source)

A vulnerability in the TCP throttling process for the GUI of the Cisco Identity Services Engine (ISE) 2.1(0.474) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device where the ISE GUI may fail to respond to new or established connection requests. The vulnerability is due to insufficient TCP rate limiting protection on the GUI. An attacker could exploit this vulnerability by sending the affected device a high rate of TCP connections to the GUI. An exploit could allow the attacker to cause the GUI to stop responding while the high rate of connections is in progress. Cisco Bug IDs: CSCvc81803.
