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;
}
