Insufficient protection of the inter-process communication functions in ABB System 800xA Base (all published versions) enables an attacker authenticated on the local system to inject data, affect node redundancy handling.

Insufficient folder permissions used by system functions in ABB System 800xA Base (version 6.1 and earlier) allow low privileged users to read, modify, add and delete system and application files. An authenticated attacker who successfully exploit the vulnerabilities could escalate his/her privileges, cause system functions to stop and to corrupt user applications.

Weak Registry permissions in ABB System 800xA Base allow low privileged users to read and modify registry settings related to control system functionality, allowing an authenticated attacker to cause system functions to stop or malfunction.
