Detailsinfo

A vulnerability was found in Swiftkey Keyboard on Samsung Galaxy (Forum Software) (affected version unknown). It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file /data/dalvik-cache of the component Language Pack Update. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22.

As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Directory traversal vulnerability in the SwiftKey language-pack update implementation on Samsung Galaxy S4, S4 Mini, S5, and S6 devices allows remote web servers to write to arbitrary files, and consequently execute arbitrary code in a privileged context, by leveraging control of the skslm.swiftkey.net domain name and providing a .. (dot dot) in an entry in a ZIP archive, as demonstrated by a traversal to the /data/dalvik-cache directory.
