We have 10 cameras with this issue:Web Server directory traversal.
Nessus plugin
10297 Web Server Directory Traversal Arbitrary File Access Web Servers High
Software version of camera :4.2.1.0(23463)
Software build date: 2019-07-02
I found an article from 2017 from vendor that says they fixed this with update, but not finding anything that will fix these cameras. Support says it cannot be fixed.
