Falsificação de Solicitação no Servidor (SSRF)

O servidor web recupera conteúdo de uma URL fornecida pelo usuário sem validar adequadamente o destino. Isso permite que um atacante force o servidor a fazer requisições para hosts internos, serviços privados ou sistemas que não deveriam ser acessíveis, contornando controles de rede e autenticação.

Example

Uma aplicação oferece um proxy de imagens: recebe a URL 'http://exemplo.com/foto.jpg' e retorna o conteúdo. Um atacante envia 'http://localhost:8080/admin' ou 'http://192.168.1.100/dados-internos', forçando o servidor a acessar sistemas internos e exfiltrar dados sensíveis.

How to mitigate

Valide e faça whitelist de domínios/IPs permitidos antes de fazer a requisição; rejeite URLs locais, privadas (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) e metadados (169.254.169.254); use DNS pinning e resoluções contínuas. Em clouds, restrinja acesso ao serviço de metadados via iptables ou IMDSv2.
