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.

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.

This Important vulnerability in WildFly domain mode allows an authenticated attacker, who has obtained the slave-secret credential, to perform arbitrary file reading on the Domain Controller's filesystem. This flaw bypasses intended access controls for file retrieval, potentially leading to sensitive information disclosure from the compromised host. Red Hat would like to thank Kelvin Mbogo (@addcontent) for reporting this issue. Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
