Description:   Foundstone warned of a vulnerability in ScreamingMedia's SiteWare web server software that allows remote users to view any file on the server.

The vulnerability reportedly allows remote users to view any world-readable file on the server.

The server's SWEditServlet CGI uses templates that are normally accessed from the "../SITEWare/Control/" directory. A remote user can use "../" characters to traverse the directory structure and specify an arbitrary file to be viewed. The file can reportedly be located anywhere on the server.

For example, the following URL will reportedly return the password file on a Sun Solaris system:


[Editor's note: Please notice that the vendor's older advisory indicates that only files within the web root directory can be accessed but the Foundstone advisory indicates that any file on the server can be accessed.]

Impact:   A remote user can view world readable files located anywhere on the server.
Solution:   The vendor plans to issue fixed versions. See the Vendor URL for the vendor's advisory.

FS Advisory ID:         FS-061201-19-SMSW

Release Date:           June 11, 2001

Product:                ScreamingMedia SITEWare

Vendor:                 ScreamingMedia Inc.

Vendor Advisory:

Type:                   Arbitrary file retrieval vulnerability

Severity:               High

Author:                 Mike Shema (
                        Foundstone, Inc. (

Operating Systems:      All operating systems

Vulnerable versions:    SITEWare 2.5
                        SITEWare 3.0

Foundstone Advisory:


        A vulnerability exists with ScreamingMedia's SITEWare Editor's
        Desktop which allows for the arbitrary viewing of world-
        readable files anywhere on the system.


        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:


        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:
