CVE-2017-6640
"Cisco Prime Data Center Network Manager Default Password Authentication Bypass"
Description
A vulnerability in Cisco Prime Data Center Network Manager (DCNM) Software could allow an unauthenticated, remote attacker to log in to the administrative console of a DCNM server by using an account that has a default, static password. The account could be granted root- or system-level privileges. The vulnerability exists because the affected software has a default user account that has a default, static password. The user account is created automatically when the software is installed. An attacker could exploit this vulnerability by connecting remotely to an affected system and logging in to the affected software by using the credentials for this default user account. A successful exploit could allow the attacker to use this default user account to log in to the affected software and gain access to the administrative console of a DCNM server. This vulnerability affects Cisco Prime Data Center Network Manager (DCNM) Software releases prior to Release 10.2(1) for Microsoft Windows, Linux, and Virtual Appliance platforms. Cisco Bug IDs: CSCvd95346.
