An unauthenticated SQL injection vulnerability exists in the Kloxo web hosting control panel (developed by LXCenter) prior to version 6.1.12. The flaw resides in the login-name parameter passed to lbin/webcommand.php, which fails to properly sanitize input, allowing an attacker to extract the administrator’s password from the backend database. After recovering valid credentials, the attacker can authenticate to the Kloxo control panel and leverage the Command Center feature (display.php) to execute arbitrary operating system commands as root on the underlying host system. This vulnerability was reported to be exploited in the wild in January 2014.
The login-name parameter passed to the lbin/webcommand.php script is not properly sanitized, which enables SQL code injection (CWE-89). An attacker can thus read the administrator password stored in the backend database without any authentication. After logging into the administrator account, the attacker exploits the Command Center feature (display.php) to execute arbitrary system commands. These commands are executed with root privileges on the host, which means complete takeover of server control.
An attacker can gain full control over the server by executing arbitrary operating system commands with root privileges — including installation of backdoors, data theft, and takeover of all hosted services.
Kloxo should be updated to version 6.1.12 or later. If updating is not possible, immediately restrict access to the Kloxo panel at the firewall level to trusted IP addresses and consider migrating to an alternative solution.
