Metasploit Framework Integrates Model Context Protocol for AI Access

The Metasploit framework has introduced support for the Model Context Protocol (MCP), a novelty that allows AI applications like Claude and Cursor to query Metasploit data through a standardized middleware. Implemented by cdelafuente-r7, the Metasploit MCP server (msfmcpd) exposes eight tools for module searching and reconnaissance data extraction, based on the official Ruby MCP SDK. This first version, available in the documentation, only supports read operations on modules, hosts, services, and vulnerabilities.

New Linux Vulnerability: Copy Fail (CVE-2026-31431)

A new Linux Local Privilege Escalation (LPE) vulnerability, identified as CVE-2026-31431 and nicknamed Copy Fail, has been made public along with a Proof of Concept (PoC). The bug, present in the cryptographic APIs of the Linux kernel, has been exploited by Metasploit with a local exploit module that works on AMD64 and AARCH64 architectures, with plans to support additional architectures in the future. The exploit replaces the 'su' binary in the page cache with a small ELF file, allowing users to specify command payloads for execution.

New Modules Added to Metasploit

The latest release of Metasploit includes three new modules:

  • Microsoft Windows HTTP to LDAP Relay: An NTLM relay module that relays from HTTP to LDAP, allowing to open an authenticated LDAP session and interact with the LDAP service in the context of the relayed identity. Contributed by jheysel-r7, the module is available in the server/relay/httptoldap path.
  • Copy Fail AFALG + authencesn Page-Cache Write: An exploit module for CVE-2026-31431, developed by Diego Ledda, Spencer McIntyre, Xint Code, and rootsecdev. The module, available in the linux/local/cve202631431copy_fail path, exploits the LPE vulnerability affecting nearly every Linux kernel since 2017.
  • Linux Execute Command: A single payload for executing commands on Linux systems. Contributed by Spencer McIntyre, the module is available in the linux/aarch64/exec path.

Improvements and Features

In addition to the new modules, the release includes several improvements:

  • The read-only MCP server of Metasploit, added by cdelafuente-r7, allows retrieving information from loaded modules and the database.
  • Improvements to verification module messages and states, contributed by adfoster-r7.

Security Implications

The integration of the Model Context Protocol represents a significant step for AI access to security data, opening new possibilities for automation and advanced analysis. However, the introduction of new exploits like Copy Fail underscores the importance of keeping Linux systems updated to prevent potential privilege escalation attacks.

Improvements and Features

Documentation and Updates

The latest Metasploit documentation is available on the docs.metasploit.com website. Users can update to the latest version of Metasploit Framework using msfupdate or download the framework from the GitHub repository. For non-Git users, open-source nightly installers and the commercial Metasploit Pro edition are available.

Security Implications

Next Steps

The Metasploit team is planning further improvements, including tools for module execution, session interaction, and database changes. These future updates aim to expand the capabilities of the MCP server and improve integration with AI applications.

Context and Impact in the Security Industry

The integration of the Model Context Protocol (MCP) in Metasploit Framework represents a turning point for the cybersecurity industry. This protocol enables smoother interaction between security systems and artificial intelligence applications, paving the way for new automated solutions for attack detection and response.

The Copy Fail vulnerability, identified as CVE-2026-31431, has sparked particular interest in the security community due to its wide scope. This exploit, which leverages a logical flaw in the cryptographic APIs of the Linux kernel, could potentially affect nearly all Linux-based systems since 2017.

Analysis of New Features

Read-Only MCP Server

The read-only MCP server implemented by cdelafuente-r7 offers a new capability for querying Metasploit data. This tool allows retrieving detailed information about loaded modules and the database, facilitating threat analysis and defense preparation.

The first iteration of the MCP server is focused on read-only operations, but the development team is already planning more advanced features for future releases, including tools for module execution, session interaction, and database changes.

HTTP to LDAP Relay Module

The new HTTP to LDAP Relay module, developed by jheysel-r7, represents a significant improvement in Metasploit's relay capabilities. This module allows establishing authenticated LDAP sessions, offering operators new possibilities to interact with LDAP services in the context of a relayed identity.

However, the use of AI applications in cybersecurity requires careful risk assessment, as automation could introduce new vulnerabilities if not managed properly.

Future Perspectives and Developments

Update Planning

The Metasploit team has several improvements planned for future releases of the MCP server. Among these, adding tools for module execution, session interaction, and database changes are key priorities.

These developments aim to expand the capabilities of the MCP server, making it an even more powerful tool for threat analysis and response.

Considerations for System Administrators

System administrators should pay particular attention to the Copy Fail vulnerability and consider applying security patches as soon as they become available. Additionally, adopting proactive security practices, such as continuous monitoring and regular system updates, is essential to mitigate risks associated with this type of vulnerability.

The integration of the Model Context Protocol also offers new opportunities for automating security activities, but requires careful planning to ensure that systems are adequately protected.

Resources and Documentation

For more information on the new features and improvements of Metasploit Framework, users can consult the official documentation. Updates can be performed using the msfupdate command or by downloading the framework from the GitHub repository.

For those who prefer commercial solutions, the Metasploit Pro edition offers a range of advanced features and dedicated technical support.
