Vulnerability Note VU#190617

LiveData ICCP Server heap buffer overflow vulnerability

Overview

LiveData ICCP Server contains a heap-based buffer overflow. This vulnerability may allow a remote attacker to crash the server.

I. Description

Inter-Control Center Communications Protocol (ICCP)

According to the LiveData ICCP Server white paper:

    The Inter-Control Center Communications Protocol (ICCP) is being specified by utility organizations throughout the world to provide data exchange over wide area networks (WANs) between utility control centers, utilities, power pools, regional control centers, and Non-Utility Generators. ICCP is also an international standard: International Electrotechnical Commission (IEC) Telecontrol Application Service Element 2 (TASE.2).
ISO Transport Service over TCP (TPKT, RFC 1006)

RFC 1006 specifies how to run the OSI transport protocol on top of TCP/IP. In the layered protocol model, RFC 1006 is situated between the TCP and OSI transport layers.

LiveData ICCP Server and LiveData Server

LiveData ICCP Server records and transmits data to other control points in process control networks. According to the LiveData ICCP Server white paper:
    The LiveData ICCP Server is based on LiveData's standard off-the-shelf software product, LiveData Server, which features a rich set of integration methods that can be easily applied to new and existing SCADA/EMS/DCS systems.
The Problem

The LiveData implementation of RFC 1006 is vulnerable to a heap-based buffer overflow. By sending a specially crafted packet to a vulnerable LiveData RFC 1006 implementation, a remote attacker may be able to trigger the overflow.

II. Impact

This vulnerability may allow a remote, unauthenticated attacker to crash a LiveData ICCP Server.

III. Solution

Upgrade

This issue is corrected in LiveData ICCP Server version 5.00.035.
