A vulnerability in the restricted security domain implementation of Cisco Application Policy Infrastructure Controller (APIC) could allow an authenticated, remote attacker to read, modify, or delete non-tenant policies (for example, access policies) created by users associated with a different security domain on an affected system.

This vulnerability is due to improper access control when restricted security domains are used to implement multi-tenancy for policies outside the tenant boundaries. An attacker with a valid user account associated with a restricted security domain could exploit this vulnerability. A successful exploit could allow the attacker to read, modify, or delete policies created by users associated with a different security domain. Exploitation is not possible for policies under tenants that an attacker has no authorization to access.
