The Lenovo Service Framework Android application uses a set of nonsecure credentials when performing integrity verification of downloaded applications and/or data. This exposes the application to man-in-the-middle attacks leading to possible remote code execution.
The product does not validate or incorrectly validates the integrity check values or "checksums" of a message. This may prevent it from detecting if the data has been modified or corrupted in transmission.
