---------------------------------------------------------------------
Description
A vulnerability exists with ScreamingMedia's SITEWare Editor's
Desktop which allows for the arbitrary viewing of world-
readable files anywhere on the system.
Details
The SITEWare Editor's Desktop is a web-based administration
front-end for ScreamingMedia content. The listening server
can be assigned an arbitrary port on which to listen. The
default login page is accessed by the URL:
/SWEditServlet?station_path=Z&publication_id=2043&template=login.tem
The SWEditServlet usually accesses templates from the
"../SITEWare/Control/" directory; however, the servlet will
follow directory path traversal. Therefore, by accessing the
SWEditServlet and requesting an arbitrary template it is
possible to view the source of that file. On a Solaris
system, the following resource path will reveal the contents
of /etc/passwd:
/SWEditServlet?station_path=Z&publication_id=2043&template=
../../../../../../../../../../../etc/passwd
Proof of concept
From a browser, make the following URL request:
http://server:port/SWEditServlet?station_path=Z&publication_id=2043&
template=../../../../../../../etc/passwd
Solution
Please contact the vendor for a solution. Customers should
obtain upgraded software by contacting their customer support
representative to obtain patches.
