Summary

On October 20th, 2017, Cisco PSIRT was notified by the internal
product team of a security vulnerability in the Cisco AMP For
Endpoints application that would allow an authenticated, local
attacker to access a static key value stored in the local application
software.

The vulnerability is due to the use of a static key value stored in
the application used to encrypt the connector protection password. An
attacker could exploit this vulnerability by gaining local,
administrative access to a Windows host and stopping the Cisco AMP for
Endpoints service.
