An issue was discovered in Kiamo before 8.4 allowing authenticated administrative attackers to execute arbitrary PHP code on the server. NOTE: the Supplier's position is that this is "a historical and intended administrative feature of the product, accessible only to already authenticated users explicitly granted administrator privileges." However, restrictions on some PHP functions were added in 8.4.
