CVE-2017-6398 is a command injection vulnerability in Trend Micro InterScan Messaging Security (Virtual Appliance) version 9.1-1600. The vulnerability exists in the saveCert.imss endpoint, which accepts user input and attempts to blacklist certain characters or patterns before passing the input as arguments to an operating system command. Due to improper blacklisting, an authenticated user can inject arbitrary commands, which are executed with root privileges, as the web server runs as root. The default installation also ships with default administrator credentials, increasing the risk of exploitation.

This repository contains a single Metasploit module (modules/exploits/linux/http/trend_micro_imsva_exec.rb) that exploits a command injection vulnerability (CVE-2017-6398) in Trend Micro InterScan Messaging Security Virtual Appliance (IMSVA) versions prior to 9.1-1600. The exploit targets the saveCert.imss HTTP endpoint, which is vulnerable to command injection via the 'commonName' POST parameter. The module first authenticates (default credentials: admin/imsva), then visits the initCert.imss endpoint to set up the session, and finally delivers a Python-based payload to achieve remote code execution as root. The default payload is a Python Meterpreter reverse shell, but any compatible Python payload can be used. The exploit requires network access to the IMSVA web interface (default port 8445, SSL), and valid credentials. The repository is structured as a standard Metasploit module, written in Ruby, and is operational for real-world exploitation.
