I'm studying SQL Injection and I have selected as target the famous ( mmm not so famous after all ) blogging platform dBlog ( http://www.dblog.it if someone is interested ) Ok, I was thinking to bypass the login form, I have studied some papers and cheat sheets and it seems feasible. The blog platform in question is written in VbScript and uses Jet database ( .mdb ) as storage. That said, I'm studying this piece of code Code: FUserID = Request.Form("UserID") FPassword = Request.Form("Password") If FUserID <> "" AND FPassword <> "" Then SQLAutori = " SELECT [Nick], [UserID], [Password], [Admin] FROM [Autori] WHERE [UserID] = '"& ControlloSQLInjection(FUserID) &"' " Set RSAutori = Server.CreateObject("ADODB.Recordset") RSAutori.Open SQLAutori, Conn, 1, 3 If NOT RSAutori.EOF Then RSAutori.MoveFirst If RSAutori("Password") = getSHAPassword(FPassword) Then Session("BLOGNick") = RSAutori("Nick") Session.TimeOut = 60 If RSAutori("Admin") = True Then Session("BLOGAdmin") = True Else Session("BLOGAdmin") = False End If the login form accepts two fields, Password and UserID, then the script verifies they are not empty and execute a query against UserID.....finally it uses the recordset obtained to verify if SHA1(Password) == stored password hash the function ControlloSQLInjection is an anti-SQL injection measure....it replaces the following characters [ --> [[ & Chr(0) ] --> []] [[ & Chr(0) --> [[] ' --> '' % --> [%] _ --> [_] # --> [#] as you can see the problem is the substitution ' -- '' I have red something about UTF7 and encodings used to bypass this kind of filters, but frankly I haven't understood the whole point at all so how can I insert a SQL statement if I can't use ' to pass ascii strings to the script? Posted: Tue Sep 18, 2007 5:40 pm waraxe Site admin Joined: May 11, 2004 Posts: 2407 Location: Estonia, Tartu Most of the real world ASP/VBscript website scripts are secured against sql injection by using substitution " '-->'' "or just removing single quote. So if you can find universal "way in", then you can do lot's of damage. So what I think is, that this kind of single quote sanitize is actually effective anti-hacking measure and can't be evaded in most cases. Still - programmers can be lazy or just stupid and trust integer parameters, using them in sql clause WITHOUT single quotes. In this case you can just walk in ... About UTF-methods - i have tried some tricks against php/mysql and php/postgresql platforms and they can work in rare cases. But against most targets it will not help (my personal opinion though ... ).

Success rate is ~ 20%, in most cases IIS webserver will refuse to serve mdb files. Still, there are hundreds websites, offering their database to anyone So i wrote little advisory about this case: http://www.waraxe.us/advisory-52.html And here is proof-of-concept screenshot: http://www.hot.ee/http123/dblog_example.png Interesting SQL Injection case www.waraxe.us Forum Index -> Sql injection You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum All times are GMT Page 1 of 1 All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 YearOldest FirstNewest First Select a forumSecurity Research by waraxe----------------General discussionHow to fixMetasploit relatedHash cracking requests----------------MD5 hashesAll other hashesHash related informationhttp://www.waraxe.us portal----------------SuggestionsCooperation proposalsSecurity bugs and issues in general----------------Newbies cornerSql injectionCross-site scripting aka XSSRemote file inclusionFull path disclosureShell commands injectionPhishing and Social EngineeringAll other security holesVarious software----------------PhpNukePostNukePhpBBXMB forumvBulletin BoardInvision Power Boarde107MamboJoomlaXOOPSM$ WindowsLinux worldAll other softwareCoppermine Photo GalleryProgramming languages----------------PhpMySqlPerlJavaJavascriptC and C++Visual BasicBorland Delphi and PascalPythonHTML and XMLAssemblerReverse engineering----------------Newbies cornerDisassemblingPHP script decode requestsMiscellaneous stuff----------------Future of the ITNanotechnologyFun cornerLinksTry2hack sitesProxy databaseDirect Downloads----------------ToolsTutorialsWordlistsRecycle Bin----------------Removed messagesOutdated posts Powered by phpBB © 2001-2008 phpBB Group
