A vulnerability has been found within the FTP client in AceFTP. When exploited, this vulnerability allows an anonymous attacker to write files to arbitrary locations on a Windows user's system.

This advisory discloses a vulnerability within the FTP client in AceFTP. When exploited, this vulnerability allows an anonymous attacker to write files to arbitrary locations on a Windows user's system.

The FTP client does not properly sanitise filenames containing directory traversal sequences (forward-slash) that are received from an FTP server in response to the LIST command.

Response to LIST (forward-slash):

-rw-r--r--    1 ftp      ftp            20 Mar 01 05:37 /../../../../../../../../../testfile.txt\r\n

By tricking a user to download a directory from a malicious FTP server that contains files with fowward-slash directory traversal sequences in their filenames, it is possible for the attacker to write files to arbitrary locations on a user's system with privileges of that user. An attacker can potentially leverage this issue to write files into a user's Windows Startup folder and execute arbitrary code when the user logs on.

Microsoft Visual Studio 2019 Community Edition Offline Download -

Before initiating the download process, ensure the following requirements are met:

After installation, verify the version:

For more details, refer to the official guide:
Create an offline installation of Visual Studio 2019

By following this guide, you will have a reliable offline installer for Visual Studio 2019 Community Edition, ready for air-gapped networks or repeated deployments.

Downloading the Microsoft Visual Studio 2019 Community Edition for offline installation is a strategic move for developers facing unreliable internet, restricted environments, or the need for standardized deployments across multiple machines. Since Microsoft no longer provides standalone ISO files for this version, the process requires creating a "local layout"—a repository of the necessary installation files. Phase 1: Obtaining the Bootstrapper

The process begins with downloading the Visual Studio Community 2019 bootstrapper from the official website. This small executable acts as the engine for the upcoming download process. For clarity in command-line operations, it is often recommended to rename this file to vs_community.exe. Phase 2: Creating the Local Layout

To download the actual installation payload, you must use the Command Prompt. This allows you to specify exactly which "workloads" (e.g., .NET desktop development, C++, or web development) to include, preventing an unnecessarily massive download.

To download the complete package (Warning: approx. 45GB+):vs_community.exe --layout C:\vslayout

To download specific workloads (Example: .NET and C++):vs_community.exe --layout C:\vslayout --add Microsoft.VisualStudio.Workload.ManagedDesktop --add Microsoft.VisualStudio.Workload.NativeDesktop --lang en-US

The --layout switch tells the bootstrapper where to store the files, and the --add switch specifies the component IDs. Phase 3: Executing the Offline Installation

Once the files are downloaded to your layout folder (e.g., C:\vslayout), you can transfer this folder to the offline machine via a USB drive or network share. Create an offline installation - Visual Studio (Windows) Before initiating the download process, ensure the following

Microsoft does not provide a single, all-in-one file for Visual Studio 2019 Community Edition. Instead, you must create a local layout

by downloading a small "bootstrapper" file and using it to download the full set of installation files for offline use. Microsoft Learn

Method 1: Creating a Full Offline Layout (For transfer to other PCs)

This method is best if you need to install Visual Studio on a machine that has no internet connection at all Microsoft Learn Download the Bootstrapper

: Get the Visual Studio 2019 Community bootstrapper from the official older downloads page Open Command Prompt : Navigate to your folder or where you saved the vs_community.exe Run the Layout Command

: Execute the following command to download the files into a local folder (e.g., C:\vslayout vs_community.exe --layout C:\vslayout --lang en-US Use code with caution. Copied to clipboard : A full download can exceed 20–35 GB

To download only specific workloads (like .NET desktop development), use:

vs_community.exe --layout C:\vslayout --add Microsoft.VisualStudio.Workload.ManagedDesktop --lang en-US Install Offline : Copy the folder to your target machine. Run vs_community.exe from within that folder using the flag to ensure it doesn't try to connect to the internet.

To download and install Visual Studio 2019 Community Edition offline, you must create a "local layout." Microsoft no longer provides a single .ISO file; instead, you download a small bootstrapper and use command-line arguments to download the full installation files. Phase 1: Download the Bootstrapper

You need the initial setup file for Visual Studio 2019 Community. Go to the Visual Studio Older Downloads page.

Expand the 2019 section and download the Community edition.

Rename the downloaded file to vs_community.exe for easier use in the next steps. Phase 2: Create the Offline Layout

Run these commands on a computer with a reliable internet connection. Open Command Prompt as an administrator. Navigate to the folder where you saved vs_community.exe.

Execute the following command to download all workloads and languages (this can exceed 35 GB): vs_community.exe --layout C:\vs2019layout Use code with caution. Copied to clipboard

Recommended (Partial Download): To save space, download only specific languages or workloads (e.g., English and .NET desktop development):

vs_community.exe --layout C:\vs2019layout --add Microsoft.VisualStudio.Workload.ManagedDesktop --includeRecommended --lang en-US Use code with caution. Copied to clipboard Phase 3: Install on the Offline Machine

Once the download is complete, transfer the C:\vs2019layout folder to your offline computer using a USB drive or network share. By following this guide, you will have a

Install Certificates (Required): Open the certificates folder inside your layout directory and install each certificate (usually by right-clicking and selecting "Install Certificate") to ensure the installer is trusted without an internet connection.

Run the Installer: Run the setup file from your layout folder using the --noWeb parameter to force it to use local files: C:\vs2019layout\vs_community.exe --noWeb Use code with caution. Copied to clipboard

Follow the on-screen instructions to complete the installation. Important Notes

Sign-in Requirement: Even for the Community Edition, you may occasionally need to connect to the internet to sign in and refresh your "free" license.

Disk Space: Ensure the destination drive on both machines has enough space; a full layout for VS 2019 is approximately 35-50 GB.

Microsoft does not provide a single monolithic ISO for VS 2019 Community anymore. Instead, you create your own offline cache using the Visual Studio Bootstrapper.

To save time and space, add workload IDs. Example – .NET desktop + C++:

vs_community.exe --layout c:\vs2019_offline --lang en-US --add Microsoft.VisualStudio.Workload.ManagedDesktop --add Microsoft.VisualStudio.Workload.NativeDesktop

Get full workload IDs from Microsoft’s documentation.
