DESCRIPTION:
A vulnerability has been discovered in Procyon SCADA, which can be
exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error within the Core
service (Coreservice.exe) when handling "LOGON" requests. This can be
exploited to cause a stack-based buffer overflow via an overly long
string sent to TCP port 23.

Successful exploitation allows execution of arbitrary code with
SYSTEM privileges.

The vulnerability is confirmed in version 1.06. Other versions may
also be affected.

SOLUTION:
Update to version 1.14.

PROVIDED AND/OR DISCOVERED BY:
Knud Højgaard, nSense via ICS-CERT and Steven Seeley, stratsec.
