# ThinkPHP ThinkPHP: ThinkPHP Remote Code Execution Vulnerability

ThinkPHP, a PHP web framework, has an unauthenticated remote code execution flaw reached through a crafted URL on the public entry point. An attacker can run arbitrary operating system commands on the server by appending a command to that request.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:ThinkPHP ThinkPHP affected ? fixed ?

## How to check

Request public/?s=index/\think\app/invokefunction&function=call_user_func_array&vars[0]=system&vars[1][]=id and look for command output in the response.

## Fix

Apply the vendor's updates for ThinkPHP per vendor instructions; the sources do not name the fixed version.
Until patched, block requests containing invokefunction or call_user_func_array at the web server or WAF.

## From the sources
