Technical details
The swmconfigupload CGI endpoint fails to properly sanitize the multipart form field name before using it as a file destination in a shell mv command. The cgiEscape() function removes HTML entities but does not strip path traversal characters (. and /) or single quotes, allowing an authenticated attacker to construct a field name such as "../../../var/status_system_interface" to write uploaded content to arbitrary filesystem locations. Because the CGI runs as root, this enables arbitrary file write with elevated privileges.
