A10 Networks AX Loadbalancer Directory Traversal

This Metasploit 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 Metasploit module works on both the hardware devices and the Virtual Machine appliances. IMPORTANT NOTE: This Metasploit 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.
