WeChall v4

Hello Challengers

This is WeChall4, finally Smile

The whole stuff is recoded from scratch, so expect many errors.
But i hope i fixed some minor bugs that were present in wc3.

List of new features:
- Multi Language
- You can now sort tables by multiple columns. (It`s a bit tricky yet unpatented)
- News announcements when an account got linked.
- Forum attachments.
- Forum got a "ThankYou", "ThumbsUp", "ThumbsDown" button.
- Avatar gallery.
- Site master table
- Usergroups and Userguestbook.
- Sites Tagged
- Challs Tagged
- Ranking by Tag
- Links can hide your username/creator now
- Account: allow a member to send you email without revealing your address
- PM Search

7 New challenges by myself:
- Thanks to all people that tested the challs and other stuff. The list of contributors is long
- Yourself PHP is an old-school xss challenge. Thx to Kender for pointing me on that flaw.
- Table Names is a mysql injection challenge where you have to find out the table and database name.
- No Escape is mysql injection challenge with an uncommon, yet interesting, flaw.
- The Guestbook is a mysql injection with an obvious flaw.
- Crappyshare is a php/curl exploit challenge.
- Paranoid is the poor try of another stegano challenge by myself. (i usually hate stegano)
- Snake is a fun challenge where you have to cheat in a browsergame.

List of (rather important) bugfixes:
- Forum-Creator for empty threads
- RSS News Feed was totally broken
- Menu not up-to-date after actions like login or read a thread
- CSTC has onsitename hidden by default
- Passwords are SHA1+salted now
- Chall solutions are case-insensitive now where ambigious
- Multiple users can share a rank now (at least considered)
- ScrewSQL has been renamed to Screwed Signup

This all has a price. We will loose all the link-votings and forum-polls Sad

Please vote for your favorite links again! NOW!

Also: Please report any bug / problem / missing feature you encounter.
Thanks!

I wish you happy challenging!

The site updates don't seem to be working for HackBBS and Rankk, maybe others. WCv4 has only been up for an hour or so since the server issue. Maybe you are already working on it.

Rankings start at #32 rather than at #1 also.

I like the challenge category ranking.

The "Icons", "Values", and "Zoom" check boxes on the "Your Stats" page don't seem to do anything.

Rankings start at #75 rather than at #1 now ...

I liked the former design better... Still have to get used to the new one, I guess.

Anyway, I thank you, and all the guys who spend hours coding these challs for us to spend hours to solve them...

All the bugs from shadum should have been fixed. Thank you for reporting them.

If anyone spot something weird, please report.

As i stated in the news, wechall4 was not really ready for release, but good enough for the server move timing.

I guess we will find a lot of bugs that are left, but i will fix them quickly Smile

Edit: And thank you flipp Smile

, your ranking bug was a duplicate from shadum... maybe some other rankings than global are broken too?
I hope you get used to the new design.

Known missing: site-icons in forum.

When i re-validate the wechall challenges i solved some days ago (after database backup), i sometimes got something like that in french (despite i set english as primary language in my profile...) "Your answer is correct but nothing change" as if i already solved this challenge ("Malware", "Fix us") which in fact was true but not in wc4...

Ok this also isn't good...http://www.wechall.net/challenge/. I see directory structure of challenges...In the directory list, installor.php. For example:

GeSHi`ed Plaintext code

Fatal error: require_once() [function.require]: Failed opening required 'html_head.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/wechall/www/wc4/challenge/Z/cookie_is_a_lie/install.php on line 3
