IBM webMethods Integration 10.15 could allow an authenticated user to upload and execute arbitrary files which could be executed on the underlying operating system.

A vulnerability classified as critical has been found in Software AG WebMethods 10.11.x/10.15.x. Affected is an unknown function of the file wm.server/connect/. The manipulation leads to improper access controls. It is possible to launch the attack remotely. To access a file like /assets/ a popup may request username and password. By just clicking CANCEL you will be redirected to the directory. If you visited /invoke/wm.server/connect, you'll be able to see details like internal IPs, ports, and versions. In some cases if access to /assets/ is refused, you may enter /assets/x as a wrong value, then come back to /assets/ which we will show the requested data. It appears that insufficient access control is depending on referrer header data. VDB-247158 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

IBM webMethods Integration 10.15 could allow an authenticated user to traverse directories on the system. An attacker could send a specially crafted URL request containing "dot dot" sequences (/../) to view arbitrary files on the system.
