{"id":"CVE-2018-14997","url":"https://www.cyber-defence.io/tools/cve/CVE-2018-14997","generatedAt":"2026-10-28T21:31:36.178Z","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 Leagoo P1 Android device with a build fingerprint of sp7731c_1h10_32v4_bird:6.0/MRA58K/android.20170629.214736:user/release-keys contains the android framework (i.e., system_server) with a package name of android that has been modified by Leagoo 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":"2019-04-25T20:29:01.000Z","lastModified":"2026-06-17T01:42:03.000Z","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-862"],"affected":["leagoo/p1 firmware"],"epss":{"score":0.00389,"percentile":0.32863,"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 (0.39%).
