Notes: Port numbers in computer networking represent communication endpoints. Ports are unsigned bit integers that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services. Well Known Ports: 0 through Registered Ports: through TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP the Internet Protocol and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery.

A major spike in activity targeting TCP Port on Windows systems may be a sign that attackers are gathering intelligence for an upcoming attack against unpatched servers, Symantec Corp. Symantec's DeepSight threat network has seen a "pretty sizable" increase in the number of sensors that have registered events on TCP Portsaid Mimi Hoang, group product manager with the company's security response team. And is the first open port used by RPC. Microsoft, in fact, has recommended that businesses block all inbound unsolicited traffic on ports and greater. By midday today, Hoang had reiterated that Symantec had not confirmed any link between the port activity and actual exploits. Exploits, however, continue to proliferate, Symantec and other security organizations said. Immunity Inc. Researchers are also positing additional attack strategies, in part because the normal routes through client PCs running WindowsWindows XP or Windows Vista aren't available. Active Directory servers may be in danger, too, said Van Horenbeeck. If your active directory server is compromised, the game is essentially over. Microsoft has said several times that it is working on a patch, but it has not yet committed to a release date. The company's next scheduled patch day is three weeks away, on May 8.

As an ethical hacker, you should glean as much information as possible after scanning your systems. You can often identify the following information:. Services running on the hosts, such as e-mail, web servers, and database applications. You can look for the following sampling of open ports your network-scanning program reports these as accessible or open :. TCP ports 80,andshowing that a web server or web proxy server is running. A continually updated listing of all well-known port numbers ports 0— and registered port numbers ports —with their associated protocols and services, is located at www. You can also perform a port-number lookup at www. You may have to dig further to find out. If you detect a web server running on the system that you test, you can check the software version by using one of the following methods:. Many web servers return an error page showing detailed version information. NMapWin can determine the system OS version. An enumeration utility such as DumpSec can extract users, groups, and file and share permissions directly from Windows. Many systems return useful banner information when you connect to a service or application running on a port. For example, if you telnet to an e-mail server on port 25 by entering telnet mail. Most e-mail servers return detailed information, such as the version and the current service pack installed. After you have this information, you and the bad guys can determine the vulnerabilities of the system. An e-mail to an invalid address might return with detailed e-mail header information. A bounced message often discloses information that can be used against you, including internal IP addresses and software versions. On certain Windows systems, you can use this information to establish unauthenticated connections and sometimes even map drives.

By default, Apache Tomcat listens on 3 ports,and A common misconfiguration is blocking port but leaving ports or open for public access. Port is less interesting and only allows shutting down the Tomcat server, while port hosts the exact same functionality as port Having the Tomcat service exposed allows attackers to access the Tomcat Manager interface. Although often password protected, brute force attacks using default and common passwords have proven successful in the past. Once access to the manager interface has been achieved, compromising the server becomes trivial with the WAR file deployment functionality. This makes communication with the AJP port rather difficult using conventional tools. The following guide will demonstrate how to configure Apache and exploit a Tomcat 7 instance, running on an Ubuntu The Ubuntu firewall was enabled with only port accessible, and weak credentials used on the Tomcat manager interface. The attacking machine was a default Kali The first line installs the mod-jk package which allows Apache to forward requests to Tomcat using the AJP protocol. It can communication to Tomcat on the local machine or to a remote instance. Visiting There are a few tools available to exploit the Tomcat manager. Metasploit contains an auxiliary module to brute force the login credentials. Configure the local IP and port accordingly. Setup a handler in Metasploit then visit the manger interface to deploy the malicious WAR. Once uploaded make sure to visit the malicious URL available in applications list at least once to cause the WAR to execute. You should have received a shell in the Metasploit handler. Preventing public access to the Tomcat manager interface is important and blocking port alone is not sufficient. Port and are just as important and should never be publically accessible. If for some reason the manager interface needs to be made available over the internet, Tomcat allows filtering access by IP address. This should be combined with a strong passphrase in the event of a spoofing attack. ProxyRequests Off. Only allow localhost to proxy requests. Order denyallow. Deny from all. Allow from localhost. Change the IP address in the below lines to the remote servers IP address hosting the Tomcat instance. Search for:.

I have a web server behind a firewall setup with NAT. Essentially traffic that comes into the external interface on my firewall on port and 80, will be forward to the web server. The local subnet that this web server is on also has access to my other subnets in my network. With that said, my concern is if my web server is hacked, the hacker will have access to other subnets in my network. So the question is: how easy or difficult it is for someone to hack and gain access to the server instance of my web server with my setup? A lot of it depends on the server and what kind of site you're running. Does it have a database backend or is it scripted? The bottom line: you should at a minimum have it located in a DMZ separated from the rest of your network. Does it have a database backend or scripted? My main concern is: Can a person use the open ports and 80 to gain access to my actual windows server instance? And then use the server instance to gain access to other subnets on my network. Then again, if you are concerned, you may want to read up about NAT vs DMZ for web servers and which to use as you should not be exposing your entire network to the Internet by placing a web server on your network directly. If the OS doesn't present any functions on those ports, you can't talk to the OS through those ports. But, you could hypothesize all sorts of ways that the application you do have listening on those ports could have a flaw that allowed you to become that application. Then, you could talk to the server because that's what the application is allowed to do. In other words, if your web server can read and write files, so can something that can take over your web server. You don't have to read much to see how common that is. The idea of the DMZ, in this case, is to limit the server's access to your network, not limit the application. Because of the above paragraph. You open up just enough for incoming queries from the WAN. And you control the access to the LAN to provide only the functions you're willing to let be compromised. If you're reading from a database, you're putting the info out there anyway, so that's not much risk. But you accept that it could download your entire database. So you put in other precautions. And so on. There maybe similar security loopholes that were patched in most modern OSe but if the web server is not properly handled by the admins running lots of 3rd party software or not patched etc. If not, get it hosted. Web and application servers, like anything else should be pen tested before being on the production network. Know and understand your risks. Silverleaf Computer Services is an IT service provider. Even though the only ports open were for http, https, and SSH, I was surprised to see in his report that there were quite a few critical vulnerabilities. Most of the vulnerabilities were a result of unpatched versions of Apache and PHP. I'm no web server expert, and this was just a test of a basic WordPress site. But I was amazed at how much info he was able to get and potentially exploit from just a URL and three little ports! If you have a public application with these ports open you should be pentesting it. Whether it be yourself or a 3rd party. Plenty of applications these days can give you lists of vulnerabilities and remediation processes for each. I agree with JeffLew07, if you canget your web site hosted and off your network entirely. Then, no worries about a penetration getting to your network through your web site. Hosting is so cost effective now days, and it also removes the hardware maintenance burden from you, as well as the bandwidth suck on your internet service, increases your uptime and you don't have to deal with hardware failures that would drop your website to keep you up at night.

This server isn't using the 1. This means getting past SSH will be at least mildly challenging. The second attack requires a private key. If you do gain access to the private SSH keys on a victim machine, you can attempt to authenticate with a large number of hosts and services using that private key. Did you know you can also brute force an SSH login with Metasploitable? At this point, we can create a session with the machine that we compromised. Logged in as user msfadmin:. Once you've got access to the file system, you'll grab a copy of the remote machine's private keys, and use them together with Metasploit to obtain access to the machine. Note that you could also plant your keys on the target, by adding your public SSH keys onto the target machine's list of trusted machines, but this technique would restrict you to a particular machine, wile the Metasploit method is portable and less intrusive. Using the public key and the above-mentioned technique would be easier, but it's worth mentioning at least. To plant your private keys on the remote machine, you'll need write access to the target user's home directory. This presumes the. If it doesn't exist, you can make it, and tamper with the filesystem. Set some options, such as the private key file, the username to log in with, and the remote host:. Execute the attack, to use the remote machine's private key to gain access to the remote machine:. Now we can use the sessions command to utilize the information we just found and set up an interactive session. We could create more mischief, by copying everyone else's private SSH keys and SSH connection histories, potentially giving us passwordless access to additional machines.

This is another use for a grepable Nmap output file. Set this value to a higher number in order to speed up your scans or keep it lower in order to reduce network traffic but be sure to adhere to the following guidelines:. However, if you also wish to import the scan results into another application or framework later on, you will likely want to export the scan results in XML format. It is always nice to have all three Nmap outputs xml, grepable, and normal. Run Nmap with the options you would normally use from the command line. In addition to running Nmap, there are a variety of other port scanners that are available to us within the framework. Remember we can issue the hosts -R command to automatically set this option with the hosts found in our database. Now that we have determined which hosts are available on the network, we can attempt to determine the operating systems they are running. In order for this type of scan to work, we will need to locate a host that is idle on the network and uses IPID sequences of either Incremental or Broken Little-Endian Incremental. In the free online Nmap book, you can find out more information on Nmap Idle Scanning. Judging by the results of our scan, we have a number of potential zombies we can use to perform idle scanning. Port Scanning.

Although Metasploit is commercially owned, it is still an open source project and grows and thrives based on user-contributed modules. As there are only a handful of full-time developers on the team, there is a great opportunity to port existing public exploits to the Metasploit Framework. Porting exploits will not only help make Metasploit more versatile and powerful, it is also an excellent way to learn about the inner workings of the Framework and helps you improve your Ruby skills at the same time. For a few other important module details, refer to the HACKING file located in the root of the Metasploit directory [Note: this has been removed in current versions of MSF, please see their documentation for further details]. There is some important information that will help ensure your submissions are quickly added to the trunk. When porting exploits, there is no need to start coding completely from scratch; we can simply select a pre-existing exploit module and modify it to suit our purposes. You may need to create the additional directories under your home directory if you are following along exactly. Note that it is possible to save the custom exploit module under the main Metasploit directory but it can cause issues when updating the framework if you end up submitting a module to be included in the trunk. Our stripped down exploit looks like this:. Now that our skeleton is ready, we can start plugging in the information from the public exploit, assuming that it has been tested and verified that it works. We start by adding the title, description, author sand references. Note that it is common courtesy to name the original public exploit authors as it was their hard work that found the bug in the first place. Everything is self-explanatory to this point and other than the Metasploit module structure, there is nothing complicated going on so far. Finding bad characters is always tedious but to ensure exploit reliability, it is a necessary evil. In this case, we need to tell Metasploit what the default filename will be for the exploit. In network-based exploits, this is where we would declare things like the default port to use. The final, and most interesting, section to edit is the exploit block where all of the pieces come together. Lastly, payload. A message is printed to the screen and our malicious file is written to disk so we can send it to our target. Everything seems to be working fine so far. Now we just need to setup a Meterpreter listener and have our victim open up our malicious file in the vulnerable application. Exploiting port 22 using Metasploit
