AXWAY SECURE TRANSPORT VULNERABILITY PASSWORD
In the example below, we attempt to log in to a server running libssh with the wrong password by typing ssh into a terminal window. In a normal SSH session, the user will attempt to log in with a username and password, and according to whether or not the credentials are valid, the server will accept or reject the connection.

How to Exploit the CVE-2018-10933 Flaw in Libssh While this is good news for most users who may be running OpenSSH, there were still thousands of devices running vulnerable versions of libssh connected directly to the internet at the time of the discovery.Įven months after the initial reporting of CVE-2018-10933, there are still plenty of devices that aren't updated yet, even though libssh released patches via libssh version 0.8.4 and libssh version 0.7.6.

Libssh is a library written in C that powers the server listening for SSH on many devices, used by major companies such as GitHub to interact with its infrastructure.ĭespite its popularity, libssh is maintained in the spare time of a small team of developers and is not as widely used as other SSH libraries, such as the more familiar OpenSSH.

This server listens for requests to connect and grants access to authorized users. What the CVE-2018-10933 Vulnerability Targetsįor an SSH connection to be created, there must be an SSH server listening on the device you want to access remotely. It makes this exploit even more notable and serious, as it potentially threatens many systems. The power that SSH allows over a device means that security is critical, which is why SSH has historically been so difficult to attack. Libssh is primarily used to interact remotely with servers, easily granting trusted users a command line interface that has complete control over the device. To do this, a protocol called SSH, or the secure shell, is often used to remotely access another networked device, allowing a user to make changes to any system they have permission to log into. For network admins and other IT professionals, configuring and updating systems they administer is a common task. What SSH Is & Why We Have a Big ProblemĬomputers underpin many of the essential systems in our society, and these systems need to be periodically accessed and updated. The vulnerability can lead to an attacker gaining complete control over a device. Due to a flaw in libssh, fooling a computer into granting SSH access is as easy as telling it you already have permission. Computers all over the world rely on a program called "libssh" to use the SSH communications protocol, which allows trusted users to log in and administer computers remotely.
