CVE-2020-15415 is a remote command execution vulnerability affecting DrayTek Vigor3900, Vigor2960, and Vigor300B devices before version 1.5.1. The flaw is in the cgi-bin/mainfunction.cgi/cvmcfgupload functionality, which improperly handles a supplied filename parameter. When a request uses the text/x-python-script content type, shell metacharacters embedded in the filename are not safely neutralized before being passed to a shell or shell-interpreted command context, allowing arbitrary command execution on the device. This is a distinct issue from CVE-2020-14472.
