Medium 4.0 AV:N/AC:L/Au:S/C:P/I:N/A:N
Description
The "loc" Parameter of the appeditor is vulnerable to directory traversal,
which allows the viewing of arbitrary files.
Admin credentials are required to view files. It should be noted that an admin
already has code execution via the designated PHP file editor. Still, this is
an access violation in the context of this component.
