Insufficient protection of the inter-process communication functions in ABB System 800xA for DCI (all published versions) enables an attacker authenticated on the local system to inject data, allowing reads and writes to the controllers or cause windows processes to crash.

Insufficient protection of the inter-process communication functions in ABB System 800xA for MOD 300 (all published versions) enables an attacker authenticated on the local system to inject data, allowing reads and writes to the controllers or cause windows processes to crash.

Improper Input Validation vulnerability in ABB 800xA, Control Software for AC 800M, Control Builder Safe, Compact Product Suite - Control and I/O, ABB Base Software for SoftControl allows an attacker to cause the denial of service.

Insertion of Sensitive Information into Log File vulnerability in ABB QCS 800xA, ABB QCS AC450, ABB Platform Engineering Tools.

An attacker, who already has local access to the QCS nodes, could successfully obtain the password for a system user account. Using this information, the attacker could have the potential to exploit this vulnerability to gain control of system nodes.

This issue affects QCS 800xA: from 1.0;0 through 6.1SP2; QCS AC450: from 1.0;0 through 5.1SP2; Platform Engineering Tools: from 1.0:0 through 2.3.0.
