It is, therefore, affected by an insufficient access control vulnerability on its com_media deletion endpoint. An 
unauthenticated, remote attacker could exploit this to delete arbitrary files on an affected system.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
