The LiveData Protocol Server fails to properly handle requests. This vulnerability may allow a remote attacker to execute arbitrary code.
The LiveData Protocol Server is real-time data acquisition and processing software used to record and transmit data among process control networks in SCADA environment. A vulnerability exists in the way LiveData Protocol Server handles requests for Web Services Description Language (WSDL) files that may allow a remote attacker to execute arbitrary code. According to iDefense Security Advisory 05.02.07:
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 call. 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.
A remote, unauthenticated attacker may be able to execute arbitrary code or cause a denial of service.
This vulnerability was reported in iDefense Security Advisory 05.02.07.
