Loading vulnerability…
A stack-based buffer overflow exists in the AgentX::receive_agentx function of the AgentX++ C++ SNMP library (v1.4.16), as used in RealNetworks Helix Server and Helix Mobile Server versions 11.x through 13.x and potentially other products. The flaw allows remote attackers to execute arbitrary code by sending crafted data to the AgentX master port (TCP 705). No authentication is required for exploitation. The vulnerability is confirmed exploitable on Windows systems, where the AgentX master process may run with SYSTEM privileges. Linux systems are not exploitable due to compiler-level stack protections.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability (CVE-2010-1318) in the AgentX++ library as used by Real Networks' Helix Server (master.exe) versions 12 and 13 on Windows. The exploit works by sending a specially crafted sequence of TCP packets to the service listening on port 705, overflowing a stack buffer and allowing arbitrary code execution. The module is operational and allows the attacker to select a Metasploit payload (up to 1024 bytes, with no bad characters), which will be executed with the privileges of the service (typically SYSTEM). The exploit does not work if Data Execution Prevention (NX/XD) is enabled. The code is written in Ruby and follows the standard Metasploit module structure, with all logic contained in a single file. No external endpoints or domains are hardcoded, but the exploit targets the local network service on TCP port 705.
