What I found was that you could inject commands into the parameter. This marks the script as a parameter-script and you can pass parameters to it when running it. Microsoft Live Response allows this, by letting you tick "Script parameters" when uploading. Sometimes you need to be able to pass parameters to script too. This way you can upload a script-toolkit to the repository and allow every member of your team run them, but only scripts signed with a trusted signing certificate (limit access to those certificates of course) may upload a executable script. (this is the default setting and should not be disabled). To further secure the environment and accomplish this, one should only allow digitally signed scripts. But one should also keep the number of users that can upload new scripts to a minimum. The problem here, is that you probably want members of your security operations team to have the ability to run scripts, like if you have uploaded a script-toolkit to your repository. The console runs in the context of "NT System", so you can imagine the impact if an account with Advanced commands rights got compromised. The "basic commands" are very restricted, but the "advanced commands", give you ability to upload Powershell-scripts to a repository and run them on any computer you connect to. Depending on the role that's been granted to you, you can run basic or advanced live response commands. The Live Response console, is basically a restricted Powershell shell with its own commands. Send suspicious entities for analysis, remediate threats, and proactively hunt for emerging threats. Live response is designed to enhance investigations by enabling your security operations team to collect forensic data, run scripts, This gives you the power to do in-depth investigative work and take immediate response actions to promptly contain identified threats in real time. Live response gives security operations teams instantaneous access to a device (also referred to as a machine) using a remote shell connection.

Using this batchfile, an authenticated attacker can upload 2 dll-files, doing DLL-Hijack by proxy. By placing a proxy-DLL named version.dll exploiting the path traversal vulnerability, this DLL will proxy imports to the original version.dll also uploaded in the application directory, with the name version32.dll, one will gain Remote Code Execution on the server as NT System.

It is importing several Windows DLL-files, like version.dll. The service-application is vulnerable to a DLL search order hijack. CWE-427: Uncontrolled Search Path Element An attacker would need a user account on the TitanFTP server, to upload the files. As a result, an attacker can send a request with the malicious parameter to bypass the intended directory and access unauthorized files. The vulnerability exists because the server does not properly validate the user-supplied newPath parameter. This can allow an attacker to access sensitive files and execute arbitrary code. An attacker can exploit this vulnerability by providing a specially crafted newPath parameter that contains directory traversal sequences (e.g., './') to move a file to a directory outside the intended directory.
TitanFTP Server is vulnerable to a path traversal attack in the move-file function. Titan FTP Server Path Traversal Vulnerability in move-file Function Version: < 2.
