Summary
A path traversal flaw was found in WildFly's domain mode implementation.
The LocalFileRepository.getFile() 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.
Affected products named by the advisory: Red Hat JBoss Enterprise Application Platform 7; Red Hat JBoss Enterprise Application Platform 8; Red Hat JBoss Enterprise Application Platform Expansion Pack; Red Hat Single Sign-On 7.
