Insecure deserialization in zenon internal DLLs

A vulnerability exists by allowing low-privileged users to read and update the data in various directories used by the Zenon system. An attacker could exploit the vulnerability by using specially crafted

programs to exploit the vulnerabilities by allowing them to run on the zenon installed hosts.

This issue affects ABB Ability™ zenon: from 11 build through 11 build 106404.
