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.

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.
