Summary

  o 
    A vulnerability in the user management functionality of Cisco Enterprise
    NFV Infrastructure Software (NFVIS) could allow an authenticated, remote
    attacker to perform a denial of service (DoS) attack against an affected
    system.

    The vulnerability is due to insufficient validation of user-provided input.
    An attacker could exploit this vulnerability by logging in with a highly
    privileged user account and performing a sequence of specific user
    management operations that interfere with the underlying operating system.
    A successful exploit could allow the attacker to permanently degrade the
    functionality of the affected system.

    There are no workarounds that address this vulnerability.
