Published

Verizon Cloud for Android (com.vcast.mediamanager) before 26.7.10 contains a path traversal vulnerability that allows co-resident malicious applications to write attacker-controlled bytes outside the intended staging directory by supplying a crafted _display_name value containing path-traversal sequences through exported activities OneTouchUploadActivity and PrintShopCloudActivity. Attackers can exploit the unsanitized filename concatenation in the file-staging sink via ACTION_SEND or ACTION_SEND_MULTIPLE intents to achieve arbitrary file write and inject attacker-controlled content into the authenticated user's Verizon Cloud account without user interaction.
