DNS Lookup - Command injection - nslookup and ncat relocation error
Hello Emiliano. I was not able to reproduce the bug on Ubuntu 16.04; however, I see others having this issue at https://unix.stackexchange.com/questions/119946/can-not-execute-some-shell-command-from-php and other sites. I think there might be a problem with the libraries the system is using to perform cryptographic operations. I dont think its in the Mutillidae code.
Thanks for the help

Please try to install PHP-XML. Since your version of PHP is 7, the package is probably called php7.0-xml or similar. On Ubuntu, the package can be installed via apt-get. Also, you might want to enable warnings and errors in PHP configuration file. That way if an error occurs, you wont see a blank screen.
