A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow an unauthenticated, remote attacker to acquire a valid session token with administrator privileges, bypassing user authentication. The vulnerability is due to insufficient request header validation during the authentication process. An attacker could exploit this vulnerability by sending a series of malicious requests to an affected device.
