This vulnerability allows remote attackers to execute arbitrary code on affected installations of Visualware MyConnection Server. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.\n\nThe specific flaw exists within the doPostUploadfiles method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of root.
