Red Hat WildFly: improper access control

A flaw was found in WildFly. A user with the Monitor role, which is the lowest standard Role-Based Access Control (RBAC) role, can exploit a path traversal vulnerability in the take-snapshot operation. By manipulating the name parameter, this user can write a copy of the server configuration to an arbitrary location. This allows the Monitor role to read back the server configuration, including sensitive credentials, which would otherwise be restricted by RBAC, leading to information disclosure.
