PKT vulnerability is rated as High severity due to the fact that it can lead to remote code execution.
In order to exploit this vulnerability, an attacker would have to craft a malicious PKT file that can be consumed through the consumption of an application that supports file upload functionality. Currently, there are few applications that support file upload functionality that includes SubassemblyComposer.exe application.
If you are affected by this vulnerability and you believe that there is no way for you to open a malicious PKT file, you can request for a patch from the vendor. In case you are unable to patch the software that you are using, you should consider disabling file upload functionality in the application.

Vulnerability Details

PKT vulnerability is a type of memory corruption vulnerability that can lead to remote code execution. The severity of this vulnerability is rated as High due to the fact that it can lead to remote code execution, which makes it easier for an attacker to exploit.
In order to exploit this vulnerability, an attacker would have to craft a malicious PKT file that could be consumed through the consumption of an application that supports file upload functionality. Currently, there are few applications that support file upload functionality and include SubassemblyComposer.exe - however, more applications may be affected in the future.
If you are affected by this vulnerability and you believe that there is no way for you to open a malicious PKT file, you can request for a patch from the vendor. In case you are unable to patch the software or operating system that you are using, you should consider disabling file upload functionality in the application.

Summary Of PKT Vulnerability

This vulnerability can be exploited by attackers to gain remote code execution if the file is consumed through an application that supports file upload functionality. Currently, there are few applications that support file upload functionality, which includes SubassemblyComposer.exe. If a user is affected by this vulnerability, they should consider disabling file upload functionality in order to prevent this vulnerability from being exploited.

Identifying software that supports file upload functionality

In order to identify the software that supports file upload functionality in your system, you can go through the below process.
1) In the search bar of your taskbar, type "file"
2) For each result that appears, click on "properties" and check if it has "support for file upload" in its properties
3) If there is an application with support for file upload, disable it.
