Path Traversal in WildFly Domain Mode

Publication date: 2026-08-04

Last updated on: 2026-08-04

Assigner: Red Hat, Inc.

Description
A path traversal flaw was found in WildFly's domain mode implementation. The LocalFileRepository.getFile() and getConfigurationFile() methods in wildfly-core/deployment-repository do not validate that the resolved file path remains within the configured repository or configuration root directories. A remote attacker who has obtained the slave host controller secret or compromised a slave host controller can supply a crafted relative path containing directory traversal sequences (e.g., ../../etc/passwd) via the slave-DC wire protocol, causing the Domain Controller to resolve and serve arbitrary files readable by the DC process. This leads to unauthorized disclosure of sensitive information such as configuration files, keystores, and system credentials.

CWE ID Description
CWE-22 The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.

Executive Summary

This vulnerability is a path traversal flaw in WildFly's domain mode. It allows an attacker with access to a slave host controller to supply crafted paths that bypass directory restrictions. The methods LocalFileRepository.getFile() and getConfigurationFile() fail to validate file paths, enabling access to files outside intended directories.

Detection Guidance

Detect this vulnerability by checking WildFly domain mode configurations for unauthorized file access attempts. Monitor logs for suspicious paths containing directory traversal sequences like ../../. Look for failed file reads in WildFly logs or unusual network traffic patterns involving the slave-DC wire protocol.

Impact Analysis

An attacker could exploit this to read sensitive files on the system running the Domain Controller. This includes configuration files, keystores, and system credentials. The impact is unauthorized information disclosure, potentially leading to further attacks or data breaches.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR, HIPAA, and other regulations by exposing sensitive personal or health data. Unauthorized access to credentials or configuration files may violate data protection requirements, resulting in legal penalties or reputational damage.

Mitigation Strategies

Immediately update WildFly to the latest patched version. Restrict network access to the slave host controller and Domain Controller. Rotate all slave host controller secrets and credentials. Review and restrict file permissions for WildFly processes to limit exposure.
