(SSH.com Communications) SSH Tectia (SSH < 2.0-6.1.9.95 / Tectia 6.1.9.95) - Remote Authentication Bypass
https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/23082.zip SSH Tectia Remote Authentication Bypass Tectia is the commercial OpenSSH solution. The product can be found at: www.tectia.com An attacker in the possession of a valid username of an SSH Tectia installation running on UNIX (verified: AIX/Linux) can login without a password. The bug is in the SSH USERAUTH CHANGE REQUEST routines which are there to allow a user to change their password. A bug in this code allows an attacker to login without a password by forcing a password change request prior to authentication. The vulnerability has been verified on UNIX operating systems and at least on this (recent) versions: • SSH-2.0-6.1.9.95 SSH Tectia Server (Latest available version from www.tectia.com) • SSH-2.0-6.0.11.5 SSH Tectia Server A default installation on Linux (version 6.1.9.95 of Tectia) is vulnerable to the attack.
