Vulnerability description
The specialists of the Positive Research center have detected a vulnerability related with abuse of functionality in Cisco ISE web interface.
Any user authenticated via web interface can download arbitrary files from their backend operating system using a specific URL. When the URL is referred to, the specified file is being deleted on the backend OS file system even if the user cancels the download.
