Description

Improper verification of a user input in Open Source MANO v7-v12 allows an authenticated attacker to execute arbitrary code within the LCM module container via a Virtual Network Function (VNF) descriptor. An attacker may be able execute code to change the normal execution of the OSM components, retrieve confidential information, or gain access other parts of a Telco Operator infrastructure other than OSM itself.
