LiveData Protocol Server Heap Overflow Vulnerability

iDefense Security Advisory 05.02.07
May 02, 2007


LiveData is a provider of real-time data acquisition and processing
software. LiveData Protocol Server is used in SCADA environments to
record and transmit data to other control points in process control
networks. The LiveData server includes a HTTP server that offers a SOAP
interface to the product. More information is available at the vendor's
web site at the following URL.


Remote exploitation of a heap overflow vulnerability within LiveData's
Protocol Server could allow an attacker to cause the service to crash
or potentially execute arbitrary code with SYSTEM privileges.

The vulnerability specifically exists due to the the handling of
requests for
WSDL files. By supplying a specially crafted request to the service on port
8080, an attacker is able to supply a negative length value to a strncpy
This value is interpreted by strncpy as a very large positive value. As a
result, a memory access violation occurs when attempting to write data
past the
end of the heap memory segment.


Exploitation allows an attacker to crash the LiveDataServer service or
potentially execute arbitrary code.

Arbitrary code execution would depend on overwriting heap data that is
used within a different thread. A race condition would have to exist
where the flow of execution would be diverted before the application
terminated from the memory access violation.


iDefense has confirmed the existence of this vulnerability in LiveData
Protocol Server version 5.00.045 which was the current release as of
September 13th 2006.


In order to mitigate potential exploitation, iDefense recommends
blocking access to port 8080 by using a firewall.


LiveData has addressed this vulnerability with updated versions of their
software. The following versions are reported to be fixed.

  RTI update 500062
  Protocol Server update 500062
  Maintenance Server update 500062


A Mitre Corp. Common Vulnerabilities and Exposures (CVE) number has not
