Directory Traversal in JBoss Undertow on Windows

IdentifiersCVE-2014-7816CWE-22· Improper Limitation of a Pathname…

CVE-2014-7816 is a directory traversal vulnerability in JBoss Undertow affecting 1.0.x before 1.0.17, 1.1.x before 1.1.0.CR5, and 1.2.x before 1.2.0.Beta3 when deployed on Windows. The flaw allows remote attackers to supply '..' path traversal sequences in a resource URI, causing Undertow to improperly limit the pathname to the intended restricted directory and enabling access to files outside the web root or configured resource directory. The issue is specific to Windows-based deployments of the affected Undertow versions.

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 unauthenticated remote attacker to read arbitrary files accessible to the Undertow process on the underlying Windows host. Depending on file permissions and deployment context, this can expose application source, configuration files, credentials, keys, logs, or other sensitive local files, potentially facilitating further compromise.

Mitigation

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

If immediate patching is not possible, reduce exposure of affected Undertow services on Windows by restricting network access to trusted clients, minimizing or disabling direct access to static resource handlers where feasible, and ensuring the Undertow process runs with least-privilege file-system permissions to limit readable files. No specific vendor workaround beyond upgrading is provided in the supplied content.

Remediation

Patch, then assume compromise.

Upgrade Undertow to a fixed release: 1.0.17 or later on the 1.0.x branch, 1.1.0.CR5 or later on the 1.1.x branch, or 1.2.0.Beta3 or later on the 1.2.x branch. Validate that all Windows-based deployments using undertow-core have been updated and redeployed with the patched version.

wildfly_traversal.rbMaturityWeaponizedFrameworkmetasploitVerified exploit

This repository contains a single Metasploit auxiliary scanner module (modules/auxiliary/scanner/http/wildfly_traversal.rb) that exploits a directory traversal vulnerability (CVE-2014-7816) in the WildFly 8.1.0.Final web server (JBoss Undertow) running on Windows. The module sends a crafted HTTP GET request with a Windows-style directory traversal sequence (..\) to read arbitrary files from the server's filesystem, defaulting to 'standalone\configuration\standalone.xml'. The exploit is network-based, targeting port 8080, and is only effective against Windows installations of WildFly. The code is written in Ruby and is designed to be run within the Metasploit framework. The module saves any successfully retrieved files for later analysis. The repository is structured as a single Ruby file, with clear references to the affected product, CVE, and usage instructions.
