Ruckus download configuration file

As we know, when you boot your Windows machine, it checks all the necessary configuration files required to make a successful startup. Therefore, if any of the files involved in this process are corrupted or missing, Windows will not be able to boot the system at all.

Here, if the BCD boot file is corrupted or missing, you're likely to receive a message that reads, "The Boot Configuration Data for your PC is missing or contains errors. Don't worry! Next, follow these steps:. Here, we use the Windows 10 installation disk for example to show how to fix the error code: 0xc Restart your Windows and check whether you still receive "The Boot Configuration Data file is missing" error message in your Windows If yes, continue with the next method.

Solution 2. If this method still cannot fix the Boot Configuration Data file is missing in Windows 10, then you can try the next method to fix the BCD is missing issue. Some users reported that they encountered "The Boot Configuration Data file is missing some required information" issue because they had set a wrong partition as active. Then it copies every segment to a temp buffer.

Since it expects numbers, it uses a very small buffer. There was an attempt to secure the code by using strncpy. However, it used the entire string length for n.

As for ASLR - since zap is forked from emfd we used a brute force approach to overcome its 9 bit of randomness. This attack scenario includes an arbitrary file write using the zap executable CVE Let us understand how emfd executes shell commands. Some of them are direct calls to functions in libc, such as system , popen , and execve. Others call a wrapper that runs a shell script handler.

This diversity in shell execution calls indicates that a bug, such as a command injection, might be feasible. From the above functions, system is the easiest one to exploit. It also appears to have a high reference count Our goal was to find a function that calls system in a way that we can control its argument. All 4 functions are reachable from doCommand via AjaxCmdStat , with the same mechanism described in scenario two.

This page checks for session authentication. If the session is valid, all 4 functions should be vulnerable. We would like to focus on cmdImportAvpPort for this article.

Decompiling revealed that the uploadFile attribute is obtained from the request XML, and inserted into the command variable without sanitation. Any command injection payload should work here. Notice that a valid cookie and CSRF token are needed.

We wanted to overcome this authentication requirement. If we could write a new page that calls Delegate "AjaxCmdStat", session["cid"] ; without conditions or session checks, it would meet the requirement.

We discovered from the second scenario that we could pass unintended arguments to the zap executable, without the need for authentication. The argument -L tells zap where to write its logfile, and it has no path limitations. Therefore, we could write a file to any location we wanted. It looks like this:. We could use the same method to pass -T and -S as well. That means we had to create a zapd server that answers to zap. Fortunately, zapd.

The following example copies the file named ios-upgrade-1 from partition 4 of the Flash memory PC Card in slot 0 to the router startup configurations:. To copy a configuration file from an FTP server to a Flash memory device, complete the task in this section:.

Optional Enters global configuration mode. This step is required only if you override the default remote username or password see Steps 3 and 4. Optional Exits configuration mode.

This step is required only if you override the default remote username see Steps 3 and 4. To copy a configuration file from an rcp server to a Flash memory device, complete the tasks in this section:. Copies the configuration file from a network server to the Flash memory device using rcp.

Reply to any router prompts for additional information or confirmation. The prompting will depending on how much information you provide in the copy command and the current setting of the file prompt command.

To copy a configuration file from a TFTP server to a Flash memory device, complete the task in this section:. Reply to any Device prompts for additional information or confirmation. The copied file is renamed new-config. To reexecute the commands located in the startup configuration file, complete the task in this section:. You can clear the configuration information from the startup configuration. If you reboot the router with no startup configuration, the router will enter the Setup command facility so that you can configure the router from scratch.

To clear the contents of your startup configuration, complete the task in this section:. The startup configuration file cannot be restored once it has been deleted. This feature allows you to recover a deleted file. To delete a specifi ed configuration on a specific Flash device, complete the task in this section:.

On Class A and B Flash file systems, when you delete a specific file in Flash memory, the system marks the file as deleted, allowing you to later recover a deleted file using the undelete EXEC command.

Erased files cannot be recovered. To permanently erase the configuration file, use the squeeze EXEC command. On Class C Flash file systems, you cannot recover a file that has been deleted.
