(Pwn2Own) Softing Secure Integration Server Directory Traversal Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Softing Secure Integration Server. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the handling of OPC UA FileDirectory FileType renames. 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 in conjunction with other vulnerabilities to execute code in the context of root.
