Description

Tater is a PowerShell implementation of the Hot Potato Windows Privilege Escalation exploit.

Included In

Functions

Invoke-Tater

  • The main Tater function.

Parameters

  • IP - Specify a specific local IP address. An IP address will be selected automatically if this parameter is not used.

  • SpooferIP - Specify an IP address for NBNS spoofing. This is needed when using two hosts to get around an in-use port 80 on the privesc target.

  • Command - Command to execute as SYSTEM on the localhost. Use PowerShell character escapes where necessary.

  • NBNS - Default = Enabled: (Y/N) Enable/Disable NBNS bruteforce spoofing.

  • NBNSLimit - Default = Enabled: (Y/N) Enable/Disable NBNS bruteforce spoofer limiting to stop NBNS spoofing while hostname is resolving correctly.

  • ExhaustUDP - Default = Disabled: (Y/N) Enable/Disable UDP port exhaustion to force all DNS lookups to fail in order to fallback to NBNS resolution.

  • HTTPPort - Default = 80: Specify a TCP port for the HTTP listener and redirect response.

  • Hostname - Default = WPAD: Hostname to spoof. WPAD.DOMAIN.TLD may be required by Windows Server 2008.

  • WPADDirectHosts - Comma separated list of hosts to list as direct in the wpad.dat file. Note that localhost is always listed as direct.

  • WPADPort - Default = 80: Specify a proxy server port to be included in the wpad.dat file.

  • Trigger - Default = 1: Trigger type to use in order to trigger HTTP to SMB relay. 0 = None, 1 = Windows Defender Signature Update, 2 = Windows 10 Webclient/Scheduled Task

  • TaskDelete - Default = Enabled: (Y/N) Enable/Disable scheduled task deletion for trigger 2. If enabled, a random string will be added to the taskname to avoid failures after multiple trigger 2 runs.

  • Taskname - Default = Tater: Scheduled task name to use with trigger 2. If you observe that Tater does not work after multiple trigger 2 runs, try changing the taskname.

  • RunTime - Default = Unlimited: (Integer) Set the run time duration in minutes.

  • ConsoleOutput - Default = Disabled: (Y/N) Enable/Disable real time console output. If using this option through a shell, test to ensure that it doesn't hang the shell.

  • StatusOutput - Default = Enabled: (Y/N) Enable/Disable startup messages.

  • ShowHelp - Default = Enabled: (Y/N) Enable/Disable the help messages at startup.

  • Tool - Default = 0: (0,1,2) Enable/Disable features for better operation through external tools such as Metasploit's Interactive Powershell Sessions and Empire. 0 = None, 1 = Metasploit, 2 = Empire

Stop-Tater

  • Function to manually stop Invoke-Tater.

Usage

  • To import with Import-Module:
    Import-Module ./Tater.ps1

  • To import using dot source method:
    . ./Tater.ps1

Examples

  • Basic trigger 1 example
    Invoke-Tater -Trigger 1 -Command "net user tater Winter2016 /add && net localgroup administrators tater /add"

  • Basic trigger 2 example
    Invoke-Tater -Trigger 2 -Command "net user tater Winter2016 /add && net localgroup administrators tater /add"

  • Two system setup to get around port 80 being in-use on the privesc target
    WPAD System - 192.168.10.100 - this system will just serve up a wpad.dat file that will direct HTTP traffic on the privesc target to the non-80 HTTP port
    Invoke-Tater -Trigger 0 -NBNS N -WPADPort 8080 -Command "null"
    Privesc Target - 192.168.10.101
    Invoke-Tater -Command "net user Tater Winter2016 /add && net localgroup administrators Tater /add" -HTTPPort 8080 -SpooferIP 192.168.10.100
