Vulnerability from variot

This vulnerability allows remote attackers to create arbitrary files on affected installations of Rockwell Automation FactoryTalk View SE. Authentication is not required to exploit this vulnerability.The specific flaw exists within the handling of fileName parameter in the RegisterEDSFiles tag. The issue results in 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 SYSTEM.
