The "hacker X file" is required to move its blood to the interior. It is not allowed to open because this article has been sent to the book! Since SERV-U local authority enhances the vulnerability, everyone holds Su.exe. This is a hug. The broiler is significantly increased for a time. The quality is rising. After the special "Win2000 Virtual Host Invasion Dafa" After the extensive, everyone started to have a high-bandwidth, big memory, and even N cpu's best broilers, congratulations to congratulations ^ _ ^ (Taiwan) The audience: with the same happiness. However, I also met the use of N to fix this SERV-U local authority to improve the vulnerability, how can I improve the privilege of the old, today, today I will discuss how to grasp these broilers with my real invasion and everyone. One. A network office system has a high wind black like a cold night. I opened another high school website. How much good, how much it blows on the homepage, I am more depressed, the more you look I didn't let me go in three years, I didn't let me go in, and I didn't even remember the room. I think, how can I have to give them a wake up, hey, this is a good thing, save the responsibility of the world, who told me handsome ^ _ ^ (the smell of the audience's stinky egg fried tomatoes began to prepare). I immediately took out the X-SCAN to check all the options to have a big scan. The server is the Windows2000 advanced server version. The server only opened 80, 21, 25, 3389 port, the server should have _blank "> firewall, or open TCP / IP is filtered, and the vulnerability scan is not there. It should be SP4 latest patch. Such a server should not be out of our high school network management configuration, which is a bit can't stand, but it should be a fact. Check the IP It is Beijing Unicom, it seems to use the virtual host. Import the "next to the invasion special tool" written by the animation. This tool function is very powerful, first through Whois.Webhosting.info query All domain names bound by IP, then import software automatic query that can upload the page or forum, the database of the article system, such as the upload page of DVBBS 7.0 and the vulnerability page of the Qingchuang article system, and the network database, etc. The vulnerability page can be uploaded by the exploit using the loophole using the program. The scan results are very disappointed. This server may be new. There are only a few websites above, and there is no upload vulnerability. Figure a depressed Open the home page and wandering, the home page is written by pure html, only one classmate is ASP, using the latest version of "Safe Classification", tried to test the weak password, error. Place the default "Warm Moon Same School Call" database Address, the database address is not changed, but it has made anti-download processing. No diarrhea, 乃 捌 捌 低 绨旃 绨旃 场 保 保 捌 低 低 绻 绻 阃 苈氲 苈氲 埃 苈耄 懔 懔 懔 问题 苈耄 问题 问题 问题 淙隺 问题 问题 问题 问题 问题 问题 问题 问题 问题 问题 问题,, 是 问题 问题 问题, ", Haha, correct, enter the management page (Figure 2). After entering, I feel that the" A4 Network Teaching System "" A4 Network Teaching System "that has been introduced in the" X Archive "is a bit image. I will try to go to the page, see it. There is a "reporting document" in "Reporting Document" in "Administrative Management" to find a ocean top ASP Troja 2005, uploaded successfully, is mad, how can you not find it (Figure 3).
I found another "personal mailbox", write a letter to myself, directly with the top 2 of Shanghai Outong 2005, open the inbox, haha, the ASP accessories can be opened directly, get Webshell (Figure 4). Later, the test found that the online office system N, enter the "corporate network office system" in Baidu, OK, use the default password prompts and prompts to answer, and you will get the WebShell. You can try it. Three two figures. Despair's permissions have improved WebShell, which can modify the homepage of the website to remind the school administrator, but find this host in the process of use, huh, it is very cool, you can do it on it. , Sweep the broiler, haha, you can also hang the QQ level, excited, think about it. Since I want to make him a broiler, my suffering begins. I started to improve the permissions of the desperate. Enter net user in WebShell, the top ASP Trojan prompt "file open failed" "No Permissions". It seems that Guest has access to cmd.exe, then we have passed one of CMD.exe. Upload success. Then define the cmd.exe path in the ASP Trojari of the ocean, but it is still not possible to execute the CMD command. That then, look at the C: / Winnt / System32 / InetSRV / DATA This directory has the write permission Windows2000's directory default is EVERYONE completely controlled (see "X file 12" a difficult virtual host invasion "), cmd Upload success. Perform NET START, FTP is really useful for serv-u. I scream, hey, blame you. Then I uploaded the Serv-U local privilege lifting vulnerability Using the program Su.exe, full of hopes c: /winnt/system32/inetsrv/data/su.exe "Net Suer Intruder $ 0123123 / Add". The result returned such a result: <220 Serv-U FTP Server V5.0 for Winsock Ready ...> User Localadministrator <331 User Name Okay, Need Password. ************** **************************************> Pass #l@lide * * * * * * * * * * * * * 0 @ P <530 Not Logged in. Figure 5
It seems that the administrator has made a repair of the Serv-U local authority to improve the vulnerability. He modified the default Sverv -u administrator name or password, and the permissions will inevitably fail. Depressed! Everyone knows how much it is not easy to use vulnerability on the Windows2000 SP4 machine, so it is difficult to have such a good hole, it is blocked, I am not sweet, I am not sansle ... 55555 ... Continue to slip in the main unit, discovering that the host does not have excess service, and the way to replace the service is also a basic bubble soup. There is no effect on the code of the ASP directly plus the administrator user. Since then, I will stroll every day, that is, there is nowhere to use all the ways that can be used, and the dagger is on the poor, carry the explosive package to find the administrator to password. Third, the Liu Dark Flower Take the way to turn the dream, I always dream of my easy upgrade permission, then use WinHEX to change the Serv-U of the Serv-U of the Serv-U, and improve the vulnerability of the local authority, then the broiler can be my own I have, I can hang QQ, I can do QQ agents, hahahahaha ... (because the middle night is laughing, she is spending a belly n 1 time) Sudden ... hexadecimal .. .... Modify the default username ... password ... I thought! I woke up, excited, how can I not sleep? The result is so bad on the next day, the exam, I'm sleepy, I almost fall asleep.). Suddenly, I wanted to have a point in Dongdong. The administrator repaired this vulnerability is to change the original password #L@lk@lk; 0 @p, then the password he finished is still in the program. If I can get it, use WinHex or Xhex to serviate, do not believe it does not ask for a password. The next day, there is an old man. The title is old and stinky. For a while, I will run into the server. (The audience wears black cloaks, bringing sunglasses, really thinking that they are Nio, Han ...), open the top of the server immediately 2005, directly view the C: / Program files / serv-u / directory, success, see the list of files, find servuadmin.exe, with the ocean top 2005 "Flow Download" downloads. Excited ... nosebleed out ... come back to open servuadmin.exe with Xhex, use shortcuts Ctrl F, enter Localadministrator, click Search, haha, password, and this "Localadministrator" is a family The child is found, the password is "85457845152145"! This happens that the administrator does not modify the username, then if you have modified how we search? In fact, we will find one of the normal serv-u of the same version, search "localadministrator", find its offset address, then open the first servuadmin.exe, shortcut Ctrl g If you jump to this address, you can find the username and password. (Figure 6) What is the port of the administrator? This is simple, directly in Webshell, Netstat -an, find 127.0.0.1:XXXXX port, guess it. And the modification management port is easy to have an error, and I have modified several errors that can not be managed.
Figure 6 has a password, everything goes well, my head is relatively stupid, so I started a relatively stupid method. Upload nc.exe and su.txt to the server, then c: /winnt/system32/inetsrv/data/nc.exe 127.0.0.1 -p 43958
