Description
A vulnerability in the implementation of the system login block-for command for Cisco NX-OS Software could allow an unauthenticated remote attacker to cause a login process to unexpectedly restart causing a denial of service (DoS) condition. This vulnerability is due to a logic error in the implementation of the system login block-for command when an attack is detected and acted upon. An attacker could exploit this vulnerability by performing a brute-force login attack on an affected device. A successful exploit could allow the attacker to cause a login process to reload which could result in a delay during authentication to the affected device.
