EIP-2015-0010

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 Disk Agent (clpdiskagent.exe) is the component that is tasked with handling shared disk resources and mirror disk control. It is configured to utilize port 29004 by default to facilitate communications between agents. This vulnerability occurs during the processing of opcode 0x104 when initializing a CPROGAGT routine within the Disk Agent. An attacker is able to introduce crafted data into the clpdiskagent component to allow for arbitrary code execution.
