Descriptions CAPEC
An adversary adds a space character to the end of a file extension and takes advantage of an application that does not properly neutralize trailing special elements in file names. This extra space, which can be difficult for a user to notice, affects which default application is used to operate on the file and can be leveraged by the adversary to control execution.
Informations CAPEC
