The IBM WebSphere Application Server running on the remote host is version 7.0.0.0 through 7.0.0.45, 8.0.0.0 through 8.0.0.15, 8.5.0.x through to 8.5.5.18, or 9.0.x through to 9.0.5.5. It is, therefore, affected by a directory traversal vulnerability. An authenticated, remote attacker can exploit this by sending a specially crafted URL request containing โdot dotโ sequences (/โฆ/) to view arbitrary files on the system.
Note that Nessus has not tested for this issue but has instead relied only on the applicationโs self-reported version number.
