Ericsson Drutt Mobile Service Delivery Platform (MSDP) is a complete business support system providing an SDP center for both on- and off-portal business that includes support for the retail, advertising and wholesale of a wide range of different products and services. The MSDP was originally developed by Drutt Corporation which Ericsson bought back in 2007. Drutt was converted into Ericsson SA SD&P and they are still developing the MSDP. The platform is available in three configurations which also can be combined in the same installation: Storefront, Mobile Marketing and Open Surf.

The identified vulnerability affects the Instance Monitor component and allows a unauthenticated remote attacker to access arbitrary files on the file system.
