CVE-2014-7951Public exploit

Arbitrary file overwrite via unsanitized restore paths

Published Feb 20, 2020 · Updated Aug 6, 2024

Path traversal in Google Android 4.0.4 allows physically proximate attackers to overwrite system-owned files through ADB restore. BackupManagerService accepts parent-directory segments in tar entry paths and resolves them outside the intended application-data directory during archive restoration. Exploitation requires a direct device connection and a writable destination; the restore process cannot overwrite root-owned files.
