Security : XOOPS 2.3.2b - Security Release
Posted by phppp on 2008/12/7 7:10:00 (724 reads)
Security

The security is always on top of the list of XOOPS Developers. Therefore
the XOOPS Development Team is pleased to announce the release of XOOPS
2.3.2b, an improved XOOPS 2.3.x release.

This release is solely for a couple of critical fixes, including an XSS
vulnerability reported by Digital Sercurity Research Group (or DSRG),
potential local file inclusion vulnerability reported by DSRG, autologin
bug reported by Dylian, a backward bug in data synchronization reported
by boy0917 as well as a bug in xoopsmailer reported by ezsky.

In the 2.3.2b release we have further improved security fixes with help
from DSRG.

All XOOPS 2.3.x users are highly recommended to upgrade to this version
ASAP.

XOOPS 2.0 and 2.2 versions are not vulnerable to the XSS issues addressed
here. However, all 2.0 and 2.2 users who have the Protector module installed
are advised to upgrade to the version included in this package for local
file inclusion issues.

Download from Sourceforge repository.


System requirements
-----------------------------------

PHP:
Any PHP version >= 4.3 (PHP 4.2.x may work but is not officially supported,
PHP 5.0+ is strongly recommended)

MySQL:
MySQL server 3.23+ (MySQL 5.0+ is strongly recommended)

Web server:
Any server supporting the required PHP version (Apache highly recommended)


Downloading XOOPS 2.3.2b
-----------------------------------

Your can get this release package from the Sourceforge repository.
Both .zip and .gz archives are provided.


Installing XOOPS 2.3.2b
-----------------------------------

1. Copy the content of the htdocs/ folder where it can be accessed by your
server
2. Ensure mainfile.php and uploads/ are writable by the web server
3. For security considerations, you are encouraged to move directories
"/xoops_lib" (for XOOPS libraries) and "/xoops_data" (for XOOPS data) out
of document root, or even change the folder names.
4. Make the directory of xoops_data/ writable; Create and make the
directories of xoops_data/caches/, xoops_data/caches/xoops_cache/,
xoops_data/caches/smarty_cache/ and xoops_data/caches/smarty_compile/
writable.
5. Access the folder where you installed the htdocs/ files using your
web browser to launch the installation wizard

Installing Protector in XOOPS 2.3.2
-----------------------------------
We also highly recommend the installation of the PROTECTOR module which
will bring additional security protection and logging capabilities to your site:

To install Protector module for the first time with a new installation of XOOPS
2.3.2, copy /extras/mainfile.dist.php.protector to /htdocs/mainfile.dist.php
BEFORE installing XOOPS.

If you are upgrading an existing XOOPS Website (see below how to do it), and
Protector is already installed there, copy /extras/mainfile.dist.php.protector
to /upgrade/upd-2.0.18-to-2.3.0/mainfile.dist.php BEFORE upgrading XOOPS.

Upgrading a non UTF-8 site:
UTF-8 encoding has been introduced into XOOPS 2.3 as default charset.
However, there might be some problems with converting existent
websites from non UTF-8 charset to UTF-8.
Before there is a good enough solution for this conversion,
following settings are recommended when you upgrade an existent
website if you are not an experienced user:
- Select "Do not change" option in "Database character set and
collation" step during upgrade process
- Modify /languages/yourlanguage/global.php to use existent _CHARSET
value if it has been changed to UTF-8 in your new global.php file as

define('_CHARSET', 'UTF-8');



Upgrading XoopsEditor package:
In the XOOPS 2.3.2b package, there are five editors included:
dhtmltextarea and textarea for plain text, fckeditor, tinymce and
koivi for WYSIWYG HTML.
Since there are some directory structure changes in both fckeditor
and tinymce editors, you are recommended to remove existent editors
before uploading the new additors.
And if you are using fckeditor for modules, please modify module
specific configs following the files in /fckeditor/modules/,
especially if you use "article" module.


Debug information display level
-----------------------------------

Since XOOPS 2.3.1 debug information display level is enabled as a
temporary solution for 2.3* to show debug information to different
level of users: to all users, to members or to admins only.
The configuration can be set in /xoops_data/configs/xoopsconfig.php
A new debug information renderer is redesigned in XOOPS 3.0



Files integrity check
-----------------------------------

The full XOOPS package is released with a script able to check if all
the system files have been correctly uploaded to the server. To use it,
follow these instructions:

1. Upload the checksum.php and checksum.md5 files located in the XOOPS
package root to your XOOPS server folder (putting them next to mainfile.php).
2. Execute checksum.php with your browser
3. If necessary, re-upload the missing or corrupted system files
4. Remove checksum.php and checksum.md5 from your server


Modules
-----------------------------------

This release contains only the "system-related modules". You are invited
to browse the XOOPS modules repository to if you need additional
functionality. Note: as a new repository is being built, the current
repository is not up-to-date, PLEASE VISIT INDIVIDUAL DEVELOPERS' WEBSITES
TO MAKE SURE YOU ARE USING LATEST VERSION OF MODULES.
