Falsificação de Solicitação do Lado do Servidor (SSRF)

O servidor web recebe uma URL de um cliente e a recupera sem validar adequadamente o destino, permitindo que um atacante redirecione requisições para hosts internos, serviços privados ou IPs arbitrários. O risco é grave: exposição de dados internos, acesso a serviços administrativos, varredura de rede interna e até execução de código em sistemas conectados.

Exemplo

Uma aplicação oferece um recurso de 'baixar imagem de URL': o usuário envia `https://attacker.com/fetch?url=http://localhost:8080/admin`, e o servidor, sem validar, faz a requisição e retorna o conteúdo da página admin interna ou de um banco de dados local exposto.

Como mitigar

Valide e liste explicitamente domínios/IPs permitidos (whitelist), bloqueie ranges de IPs privados (10.0.0.0/8, 127.0.0.0/8, 169.254.0.0/16, 172.16.0.0/12, 192.168.0.0/16), use esquemas de URL permitidos (apenas http/https) e desabilite redirects automáticos ou validar o destino final. Considere usar um proxy ou gateway isolado para requisições externas.
