IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 could allow a remote attacker to traverse directories on the system. When application security is disabled and JAX-RPC applications are present, an attacker could send a specially-crafted URL request containing "dot dot" sequences (/../) to view arbitrary xml files on the system. This does not occur if Application security is enabled. IBM X-Force ID: 193556.

CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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.
