Description
Softing Secure Integration Server Exposure of Resource to Wrong Sphere 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 FileDirectory namespaces. The issue results from the lack of proper validation of user-supplied data before using it to create a server object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-20547.
