Summary

Details

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.
