Synopsis

The remote device is missing a vendor-supplied security patch.

Description

According to its self-reported version, the Cisco Application Policy Infrastructure Controller (APIC) is affected by one or more vulnerabilities. Please see the included Cisco BIDs and the Cisco Security Advisory for more information.

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID(s) CSCvc34335.
