Directory Traversal in Trend Micro OfficeScan UpdateAgent (TmListen.exe)

IdentifiersCVE-2008-2439CWE-22· Improper Limitation of a Pathname…

A directory traversal vulnerability exists in the UpdateAgent function of TmListen.exe, part of the OfficeScanNT Listener service in Trend Micro OfficeScan client versions 7.3 Patch 4 build 1367 and earlier, 8.0 SP1 before build 1222, 8.0 SP1 Patch 1 before build 3087, and Worry-Free Business Security 5.0 before build 1220. The vulnerability allows remote attackers to read arbitrary files on the affected system by sending specially crafted HTTP requests containing directory traversal sequences to the UpdateAgent endpoint.

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 remote attackers to read arbitrary files from the affected system, potentially exposing sensitive information such as configuration files, credentials, or other confidential data. This can facilitate further attacks or information disclosure.

Mitigation

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

Restrict network access to the OfficeScan client service to trusted hosts only. Use network-level controls such as firewalls to limit exposure. Monitor for suspicious HTTP requests containing directory traversal patterns targeting the UpdateAgent endpoint.

Remediation

Patch, then assume compromise.

Upgrade Trend Micro OfficeScan to version 7.3 Patch 4 build 1372 or later, 8.0 SP1 build 1222 or later, 8.0 SP1 Patch 1 build 3087 or later, or Worry-Free Business Security 5.0 build 1220 or later, as appropriate for your deployment. Apply all relevant vendor patches.

tmlisten_traversal.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit auxiliary module targeting a directory traversal vulnerability (CVE-2008-2439) in Trend Micro OfficeScan's TmListen.exe service. The exploit leverages a crafted HTTP GET request to the /activeupdate endpoint with directory traversal sequences, allowing remote attackers to read arbitrary files (such as windows\win.ini) as SYSTEM. The module is written in Ruby and is structured as a typical Metasploit auxiliary scanner, requiring the target service to be accessible on TCP port 26122. The exploit does not provide a shell or code execution, but demonstrates proof-of-concept file read capability. The code is concise, with clear references to the vulnerability and related advisories.
