This tutorial fix is targeted at e107 version 0.615, but it could apply to other versions too. I dont have time to test them - so if anyone has experience with other (old) versions then let's share it here. By the way, these are fixes for only the most critical security holes:

sql injections and remote file inclusion.

I don't have enough free time at the moment to write other patches (against xss and full path disclosure). So - feel free to post your own bug fix suggestions!


Open "e107_handlers/secure_img_render.php" and find this code fragment (~line 19):

Code:

$a=0;
while(!$mySQLserver && $a<5){
   $a++;
   $p.="../";
   @include($p."e107_config.php");
}


Change the code like so:

Code:

$a=0;
$p = '';
while(!$mySQLserver && $a<5){
   $a++;
   $p.="../";
   @include($p."e107_config.php");
}





Open "content.php" and find this code fragment (~line 29):

Code:

if($action == "content"){
   $query = "content_id='".$sub_action."' ";
   $page = LAN_60.":";
   }


Replace with this:

Code:

$query='';
if($action == "content"){
   $sub_action=intval($sub_action);
   $query = "content_id='".$sub_action."' ";
   $page = LAN_60.":";
   }




Open "news.php" and find this code fragment (~line 119):

Code:

if($action == "list"){
        $news_total = $sql -> db_Count("news", "(*)", "WHERE news_category=$sub_action");
        $query = "news_class<255 AND (news_start=0 || news_start < ".time().") AND (news_end=0 || news_end>".time().") AND news_render_type!=2 AND news_category=$sub_action ORDER BY ".$order." DESC LIMIT $from,".ITEMVIEW;
}else if($action == "item"){


Add this sanityze code, so it look like this:

Code:

if($action == "list"){
     $sub_action=intval($sub_action);
        $news_total = $sql -> db_Count("news", "(*)", "WHERE news_category=$sub_action");
        $query = "news_class<255 AND (news_start=0 || news_start < ".time().") AND (news_end=0 || news_end>".time().") AND news_render_type!=2 AND news_category=$sub_action ORDER BY ".$order." DESC LIMIT $from,".ITEMVIEW;
}else if($action == "item"){



Open "usersettings.php" and find this code fragment (~ line 1):

Code:

<?php

if(IsSet($_POST['sub_news'])){
        header("location:submitnews.php");
        exit;
}


Add this new code, so it looks like this:

Code:

<?php
$avmsg = '';
if(IsSet($_POST['sub_news'])){
        header("location:submitnews.php");
        exit;
}
