Vulnerability in SEDUM HTTP Server

    Overview

SEDUM HTTP Server v2.0 is a web server available from
http://www.frassetto.it and http://www.zdnet.com. A vulnerability exists
which allows a remote user to break out of the web root using relative
paths (ie: '..', '...').

        http://localhost/../[file outside web root]
        http://localhost/.../[file outside web root]

    Solution

No quick fix is possible.

    Vendor Status

    The author, Guido Frassetto, was contacted via <guidofrassetto.it>
and <guidoftin.it> on Sunday, January 28, 2001 regarding version 1.1 of
SEDUM. He replied promptly and stated that version 2.0 is immune to this
problem. I downloaded the new version, ran more tests, and found that
absolutely nothing is different. Since then, I have not heard back from
Guido Frassetto.
