Description

The vulnerability allows a local user to execute arbitrary os commands.

The vulnerability exists due to improper neutralization of special elements used in an os command in Executrix.getCommand() and TempFileNames when constructing a /bin/sh -c command with unvalidated IN_FILE_ENDING or OUT_FILE_ENDING values. A local user can supply specially crafted file ending values to execute arbitrary os commands.

The issue is triggered when a configured place processes a payload, and it also affects the String[] getCommand() overload used by MultiFileUnixCommandPlace.
