According to its self-reported version, Cisco Application Policy Infrastructure Controller (APIC) is affected by a vulnerability in the out of band (OOB) management interface IP table rule programming. This is due to the configuration of specific IP table entries for which there is a programming logic error that results in the IP port being permitted.An unauthenticated, remote attacker can exploit this, by sending traffic to the OOB management interface, in order to bypass configured IP table rules to drop specific IP port traffic or bypass configured deny entries for specific IP ports.
