{"id":"CVE-2018-14983","url":"https://www.cyber-defence.io/tools/cve/CVE-2018-14983","generatedAt":"2026-10-29T01:54:48.192Z","title":"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.","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.","published":"2019-04-25T20:29:00.000Z","lastModified":"2026-06-17T01:42:01.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-20"],"affected":["sony/xperia l1 firmware"],"epss":{"score":0.00357,"percentile":0.29221,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.36%).
