A vulnerability in the Cisco Application Framework component of the Cisco IOx application environment could allow an
 authenticated, remote attacker to write or modify arbitrary files in the
 virtual instance that is running on the affected device.
 The vulnerability is due to insufficient input validation of
 user-supplied application packages. An attacker who can upload a
 malicious package within Cisco IOx could exploit the vulnerability to
 modify arbitrary files. The impacts of a successful exploit are limited
 to the scope of the virtual instance and do not affect the device that
 is hosting Cisco IOx.
