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.","state":"PUBLIC","assigner":"cve@mitre.org","published_at":"2019-04-25 20:29:00","updated_at":"2019-10-03 00:03:00"},"problem_types":["NVD-CWE-noinfo","CWE-862"],"metrics":[],"references":[{"url":"https://www.kryptowire.com","name":"https://www.kryptowire.com","refsource":"MISC","tags":["Third Party Advisory"],"title":"Homepage | Kryptowire","mime":"text/html","httpstatus":"200","archivestatus":"0"},{"url":"https://www.kryptowire.com/portal/wp-content/uploads/2018/12/DEFCON-26-Johnson-and-Stavrou-Vulnerable-Out-of-the-Box-An-Eval-of-Android-Carrier-Devices-WP-Updated.pdf","name":"https://www.kryptowire.com/portal/wp-content/uploads/2018/12/DEFCON-26-Johnson-and-Stavrou-Vulnerable-Out-of-the-Box-An-Eval-of-Android-Carrier-Devices-WP-Updated.pdf","refsource":"MISC","tags":["Technical Description","Third Party Advisory"],"title":"Page not found | Kryptowire","mime":"application/pdf","httpstatus":"404","archivestatus":"200"},{"url":"https://www.kryptowire.com/portal/android-firmware-defcon-2018/","name":"https://www.kryptowire.com/portal/android-firmware-defcon-2018/","refsource":"MISC","tags":["Third Party Advisory"],"title":"Kryptowire Provides Details on DEFCON 2018 Presentation: Vulnerable Out of the Box - An Evaluation of Android Carrier Devices - Kryptowire","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2018-14997","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2018-14997","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2018","cve_id":"14997","vulnerable":"-1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"h","cpe4":"leagoo","cpe5":"p1","cpe6":"-","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2018","cve_id":"14997","vulnerable":"0","versionEndIncluding":"1","cpe1":"cpe","cpe2":"2.3","cpe3":"h","cpe4":"leagoo","cpe5":"p1","cpe6":"-","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2018","cve_id":"14997","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"leagoo","cpe5":"p1_firmware","cpe6":"-","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2018","cve_id":"14997","vulnerable":"1","versionEndIncluding":"1","cpe1":"cpe","cpe2":"2.3","cpe3":"o","cpe4":"leagoo","cpe5":"p1_firmware","cpe6":"-","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"cve@mitre.org","ID":"CVE-2018-14997","STATE":"PUBLIC"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"n/a","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"n/a"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"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.
