CVE-2015-4641: Directory traversal vulnerability in the SwiftKey language-pack update implementation on Samsung Galaxy S4,...

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.

Security readout for executives and security teams

CVE-2015-4641 affected the SwiftKey language-pack update path on several Samsung Galaxy models. A malicious or controlled update server could write files outside the intended update area and achieve privileged code execution. This is a serious mobile device risk, especially for legacy devices still used in enterprise environments. Exposure is limited to Samsung Galaxy S4, S4 Mini, S5, and S6 devices using the vulnerable language-pack update implementation. Current exposure depends on whether those legacy devices remain in service and whether vendor or carrier updates were applied. Treat this as high-priority for legacy mobile risk reduction. The main business concern is not broad modern exposure, but any remaining vulnerable phones with privileged access to email, VPN, or internal applications. Mitigation focus: Inventory and remove affected legacy Samsung Galaxy models from managed environments.; Check Samsung and carrier guidance for applicable security updates.; Apply available device firmware or security updates through trusted channels..
