CVE-2020-10915 is a remote code execution vulnerability in VEEAM One Agent version 9.5.4.4587. The vulnerability resides in the HandshakeResult method, which fails to properly validate user-supplied data, leading to unsafe deserialization of untrusted data. This flaw allows unauthenticated remote attackers to execute arbitrary code in the context of the service account running the agent.

This repository contains a Metasploit module that exploits a .NET deserialization vulnerability in Veeam ONE Agent (prior to hotfix versions 9.5.5.4587 and 10.0.1.750) on Windows. The exploit targets the HandshakeResult() method by sending a specially crafted handshake packet to the agent's TCP service (default port 2805). If the handshake fails, the agent deserializes attacker-controlled data, leading to remote code execution. The module supports multiple payload types, including command execution, file dropper, and PowerShell stager, enabling reverse shells or Meterpreter sessions. The exploit is weaponized, allowing for customizable payloads and reliable exploitation. The only file in the repository is a Ruby script structured as a standard Metasploit module, leveraging Metasploit's TCP, CmdStager, and PowerShell mixins. No hardcoded IPs or URLs are present; the main fingerprintable endpoint is the TCP port 2805 used by the vulnerable service.
