A10 Networks AX Loadbalancer Directory Traversal



This module exploits a directory traversal flaw found in A10 Networks (Soft) AX Loadbalancer version 2.6.1-GR1-P5/2.7.0 or less. When handling a file download request, the xml/downloads class fails to properly check the 'filename' parameter, which can be abused to read any file outside the virtual directory. Important files include SSL certificates. This module works on both the hardware devices and the Virtual Machine appliances. IMPORTANT NOTE: This module will also delete the file on the device after downloading it. Because of this, the CONFIRM_DELETE option must be set to 'true' either manually or by script.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/scanner/http/a10networks_ax_directory_traversal
msf auxiliary(a10networks_ax_directory_traversal) > show actions
msf auxiliary(a10networks_ax_directory_traversal) > set ACTION < action-name >
msf auxiliary(a10networks_ax_directory_traversal) > show options
    ...show and set options...
msf auxiliary(a10networks_ax_directory_traversal) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
