# Exploit Title: Budabot 4.0 - Denial of Service (PoC)# Date: 2018-10-15# Exploit Author: Ryan Delaney# Author Contact: ryan.delaney@owasp.org# Vendor Homepage: http://budabot.com/# Software Link: http://budabot.com/forum/viewtopic.php?f=8&t=1413# Version: 0.6 -> 4.0# Tested on: 4.0# CVE: CVE-2018-19290# 1. Description# In modules/HELPBOT_MODULE in Budabot 0.6 through 4.0, lax syntax validation# allows remote attackers to perform a command injection attack against the# PHP daemon with a crafted command, resulting in a denial of service or# possibly unspecified other impact. In versions before 3.0,# modules/HELPBOT_MODULE/calc.php has the vulnerable code; in 3.0 and above,# modules/HELPBOT_MODULE/HelpbotController.class.php has the vulnerable code.# 2. Proof of Concept
Start the Budabot listener, set valid configuration options, and waitfor
the chatbot to announce it's ready in-game.
Send the chatbot a private message containing "!calc 5 x 5", and the
Budabot listener will terminate.
