0x02 漏洞描述

Laravel自带的Ignition组件在开启了Debug模式时，file_get_contents()和file_put_contents()函数使用存在不安全的可能性，攻击者可以通过发起恶意请求，构造恶意Log文件等方式触发Phar反序列化，最终造成远程代码执行。默认情况下，laravel的日志文件是放置在storage/logs/laravel.log文件下，用来储存一些PHP的错误和一些堆栈追踪的相关信息。此时可以通过对该日志文件进行写操作，从而将该log文件变成恶意的phar文件。

info:
  name: Laravel with Ignition <= v8.4.2 Debug Mode - Remote Code Execution
  author: z3bd,pdteam
  severity: critical
  description: Laravel version 8.4.2 and before with Ignition before 2.5.2 allows unauthenticated remote attackers to execute arbitrary code because of insecure usage of file_get_contents() and file_put_contents(). This is exploitable on sites using debug mode with Laravel before 8.4.2.
