VShell 4.5.2 (Official) Maintenance Release Now Available

Posted on by

VShell 4.5.2 (Official) is now available for download.

This is a maintenance release to address issues found in VShell 4.5.1.

Important Notice

Prior to version 4.5.2, VShell Enterprise Edition with HTTPS could be vulnerable to a directory traversal attack using HTTP requests, allowing potentially unauthorized access to the file system.

For VShell installations using HTTP/HTTPS, we strongly recommend upgrading to the 4.5.2 release.

For more details, please visit VanDyke Software Security Advisories.

Here’s what’s new in VShell 4.5 (Official):

HTTPS support (Linux/Mac, previously Windows only)

Provide an easy-to-use, browser-based file transfer solution for staff, customers, and external partners. End users can connect to VShell Enterprise Edition with HTTPS to upload and download files, and more. No need to train end users on client software and no plugins to install. Customize the user web interface with your company colors and logo.


WebDAV support (All platforms)

VShell Enterprise Edition with HTTPS allows users to connect with a WebDAV client to upload and download files securely. Users can take advantage of WebDAV functionality to edit and collaborate on content.

Folder monitor (Windows)

Detect when new files are created, moved, or copied to a particular folder and initiate actions such as automatic transfer to another SFTP server.

CUCM configuration wizard (Windows)

Use this wizard for easier configuration of VShell to receive file uploads (backups) from Cisco Unified Communications Manager (CUCM).

Limit maximum concurrent connections for users and groups (Linux/Mac, previously Windows only)

Control how many sessions are allowed for users and groups for SSH2, SFTP, and FTPS connections. Specify the maximum number of concurrent connections for all users/groups, or set individual limits for particular users/groups.

Workgroup Edition provides more concurrent connections

The VShell Workgroup Edition now provides 25 concurrent connections (previously 10).

Fully-functional evaluation copies of VShell 4.5.2 (Official) can be downloaded and evaluated for 60 days. During evaluation, VShell evaluators have full access to VanDyke Software’s expert technical support to assist with installation, configuration, and testing.
