  "details": "HTTP::Daemon versions before 6.17 for Perl allow OS command injection via send_file().  send_file() opens its string argument with Perl's 2-arg open(). The 2-arg form interprets magic prefixes: '| cmd' and 'cmd |' open a pipe to a subprocess, '\u003e path' and '\u003e\u003e path' open the path for write or append.  Untrusted input passed to send_file() can run OS commands at the daemon process UID. The read-pipe form ('cmd |') also leaks subprocess stdout into the HTTP response body. The write-mode forms can create or truncate files at attacker chosen paths.",
