WebSpeed 3.x in OpenEdge 10.x in Progress Software Progress 9.1e, and certain other 9.x versions, allows remote attackers to cause a denial of service (infinite loop and daemon hang) via a messenger URL that invokes edit.r with no additional parameters, as demonstrated by requests for cgiip.exe or wsisa.dll with WService=wsbroker1/edit.r in the PATHINFO.
The Webspeed configuration program does not properly disable access to the WSMadmin utility, which allows remote attackers to gain privileges via wsisa.dll.
