EIP-2015-0013

A stack-based buffer overflow has been found in NEC EXPRESSCLUSTER X that can lead to remote arbitrary code execution with full SYSTEM privileges. The Transaction Server (clptrnsv.exe) is a system service configured to utilize port 29002 by default to facilitate transactions such as sending and receiving licensing data. This vulnerability occurs during the processing of opcode 0x32 when initializing a clpexescript routine within the Transaction Server. An attacker is able to introduce crafted data into the clptrnsv service to allow for arbitrary code execution.
