Unraid 6.8.0 Auth Bypass PHP Code Execution

Description

This module exploits two vulnerabilities affecting Unraid 6.8.0. An authentication bypass is used to gain access to the administrative interface, and an insecure use of the extract PHP function can be abused for arbitrary code execution as root.

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 exploit/linux/http/unraid_auth_bypass_exec
msf exploit(unraid_auth_bypass_exec) > show targets
    ...targets...
msf exploit(unraid_auth_bypass_exec) > set TARGET < target-id >
msf exploit(unraid_auth_bypass_exec) > show options
    ...show and set options...
msf exploit(unraid_auth_bypass_exec) > exploit

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.
