Progress Webspeed Messenger allows remote attackers to read, create, modify, and execute arbitrary files by invoking webutil/_cpyfile.p in the WService parameter to (1) cgiip.exe or (2) wsisa.dll in scripts/, as demonstrated by using the save,editor options to create a new file using the fileName parameter.

Progress Webspeed Messenger allows remote attackers to obtain sensitive information via a WService parameter containing "wsbroker1/webutil/about.r", which reveals the operating system and product information.

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 PATH_INFO.

The Webspeed configuration program does not properly disable access to the WSMadmin utility, which allows remote attackers to gain privileges via wsisa.dll.
