A vulnerability in the tenant security implementation of Cisco Nexus Dashboard Orchestrator (NDO) could allow an authenticated, remote attacker to modify or delete tenant templates on an affected system.

This vulnerability is due to improper access controls within tenant security. An attacker who is using a valid user account with write privileges and either a Site Manager or Tenant Manager role could exploit this vulnerability. A successful exploit could allow the attacker to modify or delete tenant templates under non-associated tenants, which could disrupt network traffic.

Weakness 

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Extended Description 

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations 

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
