Detailed vulnerability description
The vulnerability allows a remote user to execute arbitrary code.
The vulnerability exists due to improper neutralization of directives in dynamically evaluated code in PlatformConfigurationController::decodeSettingArray() when parsing platform settings from the database. A remote user can inject arbitrary PHP code into the settings to execute arbitrary code.
