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 prior to 8.5.5.17, or 9.0.x prior to 9.0.5.3. It is, therefore, affected by a command execution vulnerability. An authenticated, remote attacker can exploit this by creating a maliciously crafted file name, which would be misinterpreted as JSP content and executed.
