A bug in the popular OpenSSH allows attackers to try thousands of passwords, while the software actually after six failed logins should disconnect. The vulnerability was by a security researcher with the alias " Kingcope announced. "
OpenSSH, also known as OpenBSD Secure Shell, is a set of network tools based on the SSH protocol, and allows users to securely log on to servers for instance, or remotely manage machines. Servers that allow login via SSH are regularly targeted by brute force attacks. In the case of OpenSSH, this is limited by after six unsuccessful attempts to disconnect. By using the vulnerability, it is possible to try to open thousands of passwords via a log-in window, that by default a two minute open state.
The problem is in the latest version of OpenSSH present, the researcher says. Which warns it especially FreeBSD systems at risk, because that keyboard-interactive authentication is enabled by default. On Reddit let a reader know that the "Challenge Response Authentication no" protects against the attack and was involved in its installation standard.
