Name of the Vulnerable Software and Affected Versions Arcserve UDP versions prior to 9.2

Description The issue allows an unauthenticated remote attacker to exploit a path traversal vulnerability in the com.ca.arcflash.ui.server.servlet.FileHandlingServlet.doUpload() function to upload arbitrary files to any location on the file system where the UDP agent is installed.
