Vulnerability Note VU#603928

Overview

Ecava IntegraXor contains a stack-based buffer overflow vulnerability in the Ecava IntegraXor Human-Machine Interface (HMI) product that could allow the execution of arbitrary code.

Description

According to Ecava's website: IntegraXor is a suite of tools used to create and run a web-based HMI interface for a Supervisory Control and Data Acquisition (SCADA) system. Ecava IntegraXor is vulnerable to a stack-based buffer overflow when more than 1024 bytes are written to the fixed-size stack buffer. When an exploit sends a request greater than 1024 bytes, IntegraXor writes past the buffer bounds and corrupts memory, allowing execution of arbitrary code.

Impact

An attacker can cause the device to crash and may be able to execute arbitrary code.

Solution

Ecava has released a patch to mitigate the vulnerability and has notified its customer base of the availability of the patch.
