TITLE

Sony Xperia L1 Android Vulnerability related to input validation on devices

Trust: 0.8

sources: JVNDB: JVNDB-2018-015356

DESCRIPTION

The Sony Xperia L1 Android device with a build fingerprint of Sony/G3313/G3313:7.0/43.0.A.6.49/2867558199:user/release-keys contains the android framework (i.e., system_server) with a package name of android (versionCode=24, versionName=7.0) that has been modified by Sony or another entity in the supply chain. The system_server process in the core android package has an exported broadcast receiver that allows any app co-located on the device to programmatically initiate the taking of a screenshot and have the resulting screenshot be written to external storage. The taking of a screenshot is not transparent to the user; the device has a screen animation as the screenshot is taken and there is a notification indicating that a screenshot occurred. If the attacking app also requests the EXPAND_STATUS_BAR permission, it can wake the device up using certain techniques and expand the status bar to take a screenshot of the user's notifications even if the device has an active screen lock. The notifications may contain sensitive data such as text messages used in two-factor authentication. The system_server process that provides this capability cannot be disabled, as it is part of the Android framework. The notification can be removed by a local Denial of Service (DoS) attack to reboot the device. A security vulnerability exists in Sony Xperia L1 (build fingerprint is Sony/G3313/G3313: 7.0/43.0.A.6.49/2867558199: user/release-keys). An attacker could exploit this vulnerability to take screenshots, obtain information, or remove notifications
