description

Cisco Application Policy Infrastructure Controller (APIC) is affected by a resource lifetime control weakness. The available advisory material does not establish what an attacker can achieve or what access conditions are required.

mitigation

Update APIC to the applicable Cisco hardening release for this issue; no fixed version is recorded in the advisory data. Until updates are deployed, limit APIC management access to trusted administrators and networks.
