GLPI is an open-source asset and IT management software package that provides ITIL Service Desk features, licenses tracking and software auditing. In GLPI before version 9.5.4 non-authenticated user can remotely instantiate object of any class existing in the GLPI environment that can be used to carry out malicious attacks, or to start a “POP chain”. As an example of direct impact, this vulnerability affects integrity of the GLPI core platform and third-party plugins runtime misusing classes which implement some sensitive operations in their constructors or destructors. This is fixed in version 9.5.4.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.

Assuming a user with a given identity, authorization is the process of determining whether that user can access a given resource, based on the user’s privileges and any permissions or other access-control specifications that apply to the resource. When access control checks are not applied, users are able to access data or perform actions that they should not be allowed to perform. This can lead to a wide range of problems, including information exposures, denial of service, and arbitrary code execution.
