A vulnerability in the management web interface of Cisco Network Assurance Engine (NAE) could allow an unauthenticated, local attacker to gain unauthorized access or cause a Denial of Service (DoS) condition on the server. The vulnerability is due to a fault in the password management system of NAE. An attacker could exploit this vulnerability by authenticating with the default administrator password via the CLI of an affected server. A successful exploit could allow the attacker to view potentially sensitive information or bring the server down, causing a DoS condition. This vulnerability affects Cisco Network Assurance Engine (NAE) Release 3.0(1). The default password condition only affects new installations of Release 3.0(1).
