This vulnerability allows remote attackers to execute arbitrary code on affected installations of Schneider Electric C-Bus Toolkit. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the processing of commands sent to the C-Gate 2 Service. The issue results from the lack of proper validation of user-supplied data, which can allow the upload of arbitrary files. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
