Vulnerability details
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.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Prevents overly permissive assignments to critical resources by limiting to task needs.
The awareness and training policy mandates training on access control practices, directly reducing the likelihood of improper access control weaknesses being introduced or exploited.
Security training teaches access control policies and enforcement, reducing improper access control implementations.
The control directly enforces access controls to prevent unauthorized access, modification, or deletion of audit information and tools.
Control assessments verify that access controls are implemented correctly and operating as intended, detecting improper access control before exploitation.
Certification requires independent assessment confirming access controls are implemented correctly and effective.
