info:
|
|
name: Camaleon CMS < 2.8.1 Arbitrary File Write to RCE
|
|
author: iamnoooob,rootxharsh,pdresearch

severity: critical
|
|
description: |
|
|
An arbitrary file write vulnerability accessible via the upload method of the MediaController allows authenticated users to write arbitrary files to any location on the web server Camaleon CMS is running on (depending on the permissions of the underlying filesystem). E.g. This can lead to a remote code execution in case an attacker is able to write a Ruby file into the config/initializers/ subfolder of the Ruby on Rails application
