Windows 7
Пользователь user1 является членом группы Администраторы. Пользователь user2 является Обычным пользователем.
1. Заходим в систему под пользователем user2.
2. Выполняем команду cmd.
3. В открывшейся панели выполняем команду
runas /user:имяКомпьютераuser1 cmd
4. Открывается новая консоль. Консоль должна работать с правами Администратора, и все команды в ней исполняемые так же должны выполняться с правами Администратора.
5. Набираем в «новой» консоли, открытой с правами пользователя user1
net localgroup Администраторы user2 /ADD
6. Получаем
System error 5 has occurred.
Access is denied.А Windows XP данная техника работает, почему не работает в Windows7?
Вот что еще замечено. Если в консоли п.4 запускать secpol или gpedit, то они запускаются как и положено с правами Администратора! а вот net localgroup запустить не удается!
Как быть?

Запуск CMD Run As Administrator это понятно и это работало.
Теперь понял, запуск cmd через Run as different user не повышает привилегии… есть обходные пути в виде PowerShell-скрипта, который уже делает запрос на повышение привилегий… либо опять же через Run as administrator,
если пользователь не обладает правами локального администратора — в таком случае всё будет ок… повторюсь — эти ограничения работают только в интерактивном режиме: при гранулярном тестировании скриптов в интерактивной сессии будут ошибки-

List of CVEs: —
Routers manufactured by Netcore, a popular brand for
networking equipment in China, have a wide-open backdoor
that can be fairly easily exploited by attackers. These
products are also sold under the Netis brand name outside of
China. This backdoor allows cyber criminals to easily run
arbitrary code on these routers, rendering it vulnerable as
a security device. Some models include a non-standard echo
command which doesn’t honor -e, and are therefore not
currently exploitable with Metasploit. See URLs or module
markdown for additional options.
Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can’t (or doesn’t) reliably autodetect. More information about ranking can be found here.
Basic Usage

Verification Steps
- Install the emulator/hardware
- Start msfconsole
- Do:
use exploits/linux/misc/netcore_udp_53413_backdoor
- Do:
set RHOST <ip>
- Do:
check
- Do:
exploit
- You should get a shell.
Exploitability
As previously noted, some modules are vulnerable, but not currently exploitable via Metasploit.
During testing it was discovered that some modules implement an echo command that does not honor -ne. While it may be possible to still execute a shell, further investigation would need to be conducted.
In these cases, it should be possible to use other scripts to act as a fake interactive shell.
Scenarios
The following is an example of a vulnerable AND EXPLOITABLE router.

- How to Fix the “System Error 53 Has Occurred” Error on Windows?
By Daisy | Follow |
Last Updated October 25, 2019
A lot of users have been facing the “system error 53 has occurred” error on their network-connected computers. In this post, I will list some of the reasons due to which this error is triggered and also provide viable methods to fix it completely. You can read this post from MiniTool to get the details.
Reasons for the “System Error 53 Has Occurred” Error
Here are some main reasons for the “system error 53 has occurred” error:
1. Connection Issue
2.Background Applications
3. Security Software
4. Incorrect Share Folder Command
5. Disabled Sharing
Then I will introduce how to fix the “system error 53 has occurred” error.
How to Fix the “System Error 53 Has Occurred” Error
Method 1: Use the Correct Share Command
In most cases, an incorrect share command can cause the “system error 53 has occurred” error. The correct method of sharing is as follows:
Step 1: Press the Windows + R keys together to open the Run dialogue box.
Step 2: Type cmd and click OK to open Command Prompt.
Step 3: Type the following share command: net use F: \servershare name.
Then you can check to see if the “system error 53 has occurred” error still exists after you use this format. If it still exists, you can try the next method.
Method 2: Run Ping Test
The correct way to identify if the network server is working properly is to ping the server and check if there is a response. Here are the steps:
Step 1: Open Command Prompt again and type the following command to ping the server/computer in question:
ping (IP address of the server)
Step 2: If the Ping command returns all packets and no packets are lost, it means your network is set up correctly. However, if an error occurs or you do not receive a response when pinging the server, the connection settings are incorrect.
Step 3: Troubleshoot according to the results of the ping test.
Then you can check if the “system error 53 has occurred” has been fixed. If not, you can try the next method.
Method 3: Disable Security Software
Then you can try disabling the security software and check if it was causing the issue. If you find the issues, you should disable the security software, you can read this post — 3 Ways to Disable Windows Defender Antivirus on Windows 10.
Method 4: Check Networking in Safe Mode
If all of the methods above don’t work, you should check the network in Safe Mode. In this step, your computer will be put in safe mode to determine whether an application is causing this problem. For that:
Step 1: In the Start menu, press shift and click restart at the same time to enter the WinRE.
Step 2: You should choose Troubleshoot in Choose an option, and then choose Advanced options.
Step 3: Choose Enable Safe Mode with Networking in Advanced options and wait for the computer to startup.
Step 4: Check to see if “system error 53 has occurred” error exists in this mode.
If it doesn’t, it means that a background application was causing the issue all along. Either reinstall that application or keep it disabled.
Final Words
That is all information on how to fix the “system error 53 has occurred” error. In the post, you can also learn about the reasons for this error. I hope this post can be helpful to you.

Windows is one of the most popular operating systems out there with more than a billion users. It provides users with the ability to link their computers through a network. However, quite recently, a lot of users have been facing the “System 53 Error has Occurred” Error on their network-connected computers. This issue has mainly been common with the older operating systems.
In this article, we will discuss some of the reasons due to which this error is triggered and also provide viable solutions to fix it completely. Make sure to follow the steps accurately and in the same order in which they are presented to avoid conflict.
What Causes the “System 53 Error has Occurred” Error?
After receiving numerous reports from multiple users, we decided to investigate the issue and devised a set of solutions to fix it completely. Also, we looked into the reasons due to which it is triggered and listed them as follows.
- Connection Issue: There is a possibility that the two computers might not have been connected properly or the network through which they are connected is facing issues. If this is the case, the problem can be with the ethernet cable, the router or the configuration between the computers. These issues need to be checked and resolved through troubleshooting different options.
- Security Software: In some cases, the security software installed on either of the two computers might be preventing the connection between the two computers. Security software can detect the connection as harmful and block it entirely due to which this error can be triggered.
- Background Applications: Some background applications/tasks can also prevent the connection from being established properly. These background processes can interfere with important system functions and one of those functions might be the networking function.
- Disabled Sharing: In some cases, the sharing of files and folders might be disabled on the computer or the network card. This setting can be configured in the control panel and it needs to be enabled in order for the connection to be established properly.
- Incorrect Share Folder Command: With the majority of users, the issues were occurring due to an incorrect command being executed during sharing. It is recommended that you use the correct command with the appropriate format to share the folder.
Now that you have a basic understanding of the nature of the problem, we will move on towards the solutions. Make sure to implement these in the specific order in which they are presented to avoid conflict.
Solution 1: Using the Correct Share Command
In most cases, the issue occurs due to an incorrect share command which triggered this error. The command should display the address of the server and the folder to be shared in commas and most users forget this, due to which the issue is triggered. The correct method of sharing is:
- Press “Windows” + “R” to open the Run prompt.
- Type in “cmd” and press “Enter” to open Command Prompt.
Running Command Prompt - Type in your share command in the following format.
net use F: "\servershare name"
- Check to see if the issue persists after you use this format.
Solution 2: Running Ping Test
The correct way to identify if the network server is working properly is to ping the server and check if there is a response. In this test, we will also check if there is packet loss which can also trigger this error. To run a ping test:
- Press “Windows” + “R” to open the Run prompt.
- Type in “Cmd” and press “Enter”.
Running Command Prompt - Type in the following command to ping the server/computer in question.
ping (IP address of the server)
Result of the ping command - If the Ping command returns all the packets and there isn’t any packet loss it means that your network is set up correctly. But, if the response isn’t received or there is an error while pinging the server, it means that the connection hasn’t been set up correctly.
- Troubleshoot according to the results of the ping test.
Solution 3: Disabling Security Software
If the ping test returned a good response and the computer was being detected, it is time to disable the security software and check if it was causing the issue. Sometimes, the Antivirus installed on the computer can prevent the user from accessing the folder on a network. Therefore, disable your Antivirus and check if the connection between the computers is made and the files can be accessed on the network.
Solution 4: Enabling Sharing
In some cases, the sharing of files and hardware between computers might be disabled from the control panel. Therefore, in this step, we will be changing that setting and enabling the sharing between computers. For that:
- Press “Windows” + “R” to open the Run prompt.
- Type in “Control Panel” and press “Enter” to open it.
Opening Control Panel - Click on the “Network and Internet Settings” option and select the “Network and Sharing Center” button.
- Click on the “Change Advanced Sharing Settings” option.
Clicking on “Change Advanced Sharing Options” button - Click on All Dropdowns in the setting menu and check the “Turn On Network Discovery” and “Turn On Printer and File Sharing” options.
Configuring the File Sharing and the Network Discovery Options Note: You must enable this for both “Guest and Private” Networks.
- Click on “Apply” to save your changes and close the window.
- Check to see if the issue persists.
Solution 5: Checking in Safe Mode
In this step, we will be putting the computer in safe mode to determine whether an application is causing this problem. For that:
- Restart the computer and immediately start pressing the “F8” key rapidly.
- Wait for the boot options screen to appear and select the “Advanced Boot Options” option.
- Select “Safe Mode With Networking” and wait for the computer to startup.
Selecting the “Safe Mode With Networking” option - Check to see if the issue exists in this mode.
- If it doesn’t, it means that a background application was causing the issue all along. Start disabling applications one by one and notice the one which makes the issue go away. Either reinstall that application or keep it disabled.

Вычислительная техника всегда полностью детерминирована. В ней нет полурешений или частичных ответов. Есть только нули, есть только единицы. И если что-то не работает, то оно не работает всегда и по вполне выявимой причине. Примерно так полагали отцы-основатели храма компьютера. А потом в вычислительном блоке завелись тараканы, маленькие такие жучки, которые стохастически бегали и замыкали контакты, что приводило к ошибкам, возникающим случайным образом, к ошибкам, которые не укладываются в детерминированную, жесткую модель двоичной вычислительной техники.
С тех пор не перфолент было испорчено, а программно-аппаратные комплексы, компьютеры с которыми мы работаем, стали на несколько десятков порядков более сложными. И ошибки в них возникают порой настолько экзотические, что решить их зачастую практически невозможно, так как легче переустановить заново Windows и сбросить Linux.
Перфолента винтажная
Именно о такой «ошибке» и пойдет дальше речь. Действие происходит в среде операционной системы Windows 10. Разрядность или редакция системы не имеет значения. При попытке подключения к сервису Samba удаленного сервера в локальной сети на Linux при использовании команды net use возникает ошибка множественного доступа:
System error 1219 has occurred.
Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.
Ошибка будет возникать и при попытке подключиться к «расшареной папке» на удаленном сервере обычным проводником. Гугленье по номеру и описанию ошибки ни к каким позитивным результатам не приводит, так как ошибка настолько старая, что даже ссылки на базу знаний Microsoft ведут на страницу ошибки об отсутствии ошибки, а не на описание того, как с появившейся бедой справиться.
В моем случае я пытался подключать сетевой диск из командного файла. Операция проводилась командой:
NET USE B: \192.168.1.11BU BU2 /user:BUS /persistent:no
Где в качестве диска B: примонтировывалась папка BU с сервера, заданного IP-адресом 192.168.1.11. При этом подключение осуществлялось под пользователем BUS с паролем BU2. И подключение существовало до перезагрузки (или его можно было отключить командой NET USE B: /DELETE).
Но, начнем по порядку. Давным-давно, по причинам ведомым одним только разработчикам, да архитекторам Microsoft, сетевые подключения к сервисам удаленный папки (та самая Samba) жестко ограничивались только одним пользователем на один сервер. Что это значит? Это значит, что на один сервер можно подключиться только под одной парой Login/Password. И если вы уже открыли один такой сеанс и не отключились от него (а Windows обычно не отключает соединение, чтобы потом не тратить время на его подключение заново), то при второй попытке подключиться к этому же серверу возникает как раз ошибка 1219. Собственно, описание проблемы и способ ее решения приводится непосредственно при выводе кода 1219. Дескать надо убрать другие подключения, тогда все заработает.
Многие «решения» и советы в сети сводятся примерно к следующему:
1. Перезагрузиться. Самый универсальный совет. И таки да, все заработает, если, конечно, у вас нет какого-либо автоматического подключения к удаленному серверу по Samba в автозагрузке. (По этому поводу встречался и совсем экзотический вариант по перезагрузке сервиса Workstation, дескать быстрее, да и все остальное не закроется, но это уже какой-то Overkill).
2. Удалить существующие подключения без перезагрузки. Вариант немного сложнее, но работает не хуже. Для этого придется поработать руками. Заходим в командную строку Windows (мой любимый способ через Win-X и там уже выбрать). Вводим команду NET USE. Она возвращает нам список подключенных удаленных папок. Затем удаляем ненужное подключение через NET USE xxx /DELETE, где xxx тот ресурс в качестве которого у нас подключена удаленная папка. Либо же удаляем вообще все подключения через NET USE * /DELETE.
3. Далеко не у всех пункты 1 и 2 срабатывают. Поэтому самые hard-core users советуют заодно «почистить» всё остальное, что так или иначе касается сетевых подключений. Все делается там же, в командной строке, после проведения операции из пункта 2. Поочередно запускаем следующие команды:
ipconfig /release
ipconfig /flushdns
ipconfig /renew
Все вышеприведённые варианты должны, просто обязаны, помочь в проблеме. Но, что, если нет? Например, если NET USE возвращает, что у вас в системе нет никаких подключений? Мой NET USE просто отписывался «There are no entries in the list.», так как банально не видел подключений сделанных и сохраненных через проводника.
В таком случае поступаем другим, не менее интересным способом. Но для его понимания, нужно понять каким образом сетевой стек в Windows идентифицирует удаленные сервера. А делает он это очень просто. По какому сетевому имени к серверу подключаешься, так он его и запоминает. В моем варианте я подключался через проводник и в командном файле к серверу по его IP-адресу (192.168.1.11). Но ведь у сервера есть еще и его сетевое имя. У меня он зовется N3050. И вместо NET USE B: \192.168.1.11BU BU2 /user:BUS /persistent:no я могу вполне резонно воспользоваться NET USE B: \N3050BU BU2 /user:BUS /persistent:no и все заработает.
А если подключений к одному серверу с разными учетными данными требуется еще больше, то можно воспользоваться другой техникой: прописать в сетевые или локальные таблицы связей IP-адресов и имен дополнительные псевдонимы. В среде Windows проще всего изменить файл hosts, который обыкновенно гнездится по следующему пути WindowsSystem32driversetc.
В него можно прописать хоть десять, хоть сто псевдонимов одного и того же сервера и понаподключать такое количество подключений с разными учетками, какое только потребуется.
