Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
