Remote attackers are able to sync via itunes own files with malicious filename, artist titel or album name. The attack vector is persistent and the request method is GET. The local file/path include execute occcurs in the main `file dir index` list. The security risk of the local file include web vulnerability is estimated as high(-) with a cvss (common vulnerability scoring system) count of 7.4(+)|(-)7.5. Exploitation of the local file include web vulnerability requires no user interaction or privileged web-application user account with password. Successful exploitation of the local web vulnerability results in mobile application or connected device component compromise by unauthorized local file include web attacks.
