Proxy Command Injection in Trend Micro OfficeScan Web Console (Proxy.php)

IdentifiersCVE-2017-11394CWE-77

CVE-2017-11394 is a remote code execution vulnerability in Trend Micro OfficeScan versions 11 and XG (12), specifically within the Web Console component. The vulnerability arises from improper validation of the 'T' parameter in Proxy.php, which is parsed and passed to a system call without adequate sanitization. This allows authenticated remote attackers to inject and execute arbitrary commands on the underlying system with the privileges of the OfficeScan service.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an authenticated attacker to execute arbitrary code on the OfficeScan server, leading to full compromise of confidentiality, integrity, and availability. The attacker gains the ability to run commands as the service user, potentially leading to further lateral movement or persistence within the environment.

Mitigation

If you can’t patch tonight, do this now.

Restrict access to the OfficeScan Web Console (TCP port 4343) to trusted networks only. Deploy Trend Micro TippingPoint IPS Digital Vaccine filter ID 28006 for network-level protection. Monitor authentication logs for suspicious activity and review web server logs for anomalous requests to Proxy.php.

Remediation

Patch, then assume compromise.

Apply the security update provided by Trend Micro for OfficeScan 11 and XG (12) to address the improper input validation in Proxy.php. Ensure all OfficeScan servers are updated to the latest patched version as per Trend Micro's advisory.

trendmicro_officescan_widget_exec.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit module (Ruby file) that exploits CVE-2017-11394, a remote code execution vulnerability in Trend Micro OfficeScan (versions 11 and XG) for Windows. The exploit leverages an authentication bypass in the widget feature (via talker.php) and a command injection vulnerability (via proxy_controller.php) to achieve unauthenticated remote code execution as the web server user. The module automatically detects the target version, handles CSRF tokens and session cookies, and delivers a customizable PowerShell payload (such as a reverse shell) to the target. The exploit is weaponized, allowing for easy payload customization and integration into the Metasploit framework. The main endpoints targeted are the OfficeScan management interface over HTTPS, specifically the widget-related PHP scripts. The repository is structured as a single Ruby file designed for use within Metasploit, with clear separation of functions for authentication bypass, version detection, vulnerability checking, and exploitation.
