Scripts Nmap para detectar a vulnerabilidade 0-day do Exchange (CVE-2022-41082)
Scripts NSE do Nmap para verificar a vulnerabilidade do Exchange (CVE-2022-41082). Os scripts NSE verificam os serviços expostos mais populares na Internet. É um script básico que verifica se o patching virtual funciona.
Como não há patch atualmente - apenas soluções alternativas são verificadas se o host está vulnerável.
Exemplo simples:
nmap -sV -T4 -v --script=http-vuln-cve-2022 scanme.nmap.org
Execução mais rápida (sub-redes grandes):
nmap -p443 -T4 -v --script=http-vuln-cve-2022 10.0.0.0/16
Vulnerável:
nmap -Pn -T4 -p443 --script=http-vuln-cve2022-41082.nse 127.0.0.1
Starting Nmap 7.92 ( https://nmap.org ) at 2022-10-01 13:37 CEST
Nmap scan report for localhost (127.0.0.1)
Host is up (0.030s latency).
