CVE-2024-49421Known exploitationPublic exploit

Arbitrary file write via unsanitized transfer path

Published Dec 3, 2024 · Updated Dec 3, 2024

Path traversal in affected Samsung Quick Share Agent builds allows adjacent attackers to write transferred files to arbitrary locations. The s(JSONObject) transfer parser trusts attacker-controlled IsPrivateShare, skips Path sanitization, and uses traversal segments during folder creation. A nearby Samsung phone transferring a folder can write within directories available to the agent; affected builds precede 3.5.14.47 on Android 12, 3.5.19.41 on Android 13, and 3.5.19.42 on Android 14.
