Message-ID: <20070511093755.32699.qmail@securityfocus.com> Date: 11 May 2007 09:37:55 -0000 From: suresync@...il.com To: bugtraq@...urityfocus.com Subject: Multiple Denial of Service attacks possible for Webspeed OpenEdge Denial of Service attack against OpenEdge WebSpeed possible through dict.r. 11-5-2007 author: Eelko Neven discovered: 9-5-2007 Because of poor security in dict.r it is possible to put all agents in busy mode. First you have to find the messenger execution url. For example: http://yourmachine.com/scripts/cgiip.exe/WService=wsbroker1 http://yourmachine.com/scripts/wsisa.dll/WService=wsbroker1 just add the following to the url: /dict.r your url will look like this: http://yourmachine.com/scripts/cgiip.exe/WService=wsbroker1/dict.r When you run the above url you put the agent into an infinite loop (Do While). If for instance your server runs 5 Broker Agents you just have to run above url 5 times and then all agents will be put in busy mode. From that moment on it's not possible to access that broker anymore. Tested with Progress 10b in production mode. …………………………………………………………………………………………………… Denial of Service attack against OpenEdge WebSpeed possible through _help.r. 11-5-2007 author: Eelko Neven discovered: 9-5-2007 Because of poor security in _help.r it is possible to put all agents in busy mode.
