TITLE

MediaTek Embedded Multimedia Card Command injection vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2019-008351

DESCRIPTION

The MediaTek Embedded Multimedia Card (eMMC) subsystem for Android on MT65xx, MT66xx, and MT8163 SoC devices allows attackers to execute arbitrary commands as root via shell metacharacters in a filename under /data, because clear_emmc_nomedia_entry in platform/mt6577/external/meta/emmc/meta_clr_emmc.c invokes 'system("/system/bin/rm -r /data/' followed by this filename upon an eMMC clearance from a Meta Mode boot. NOTE: compromise of Fire OS on the Amazon Echo Dot would require a second hypothetical vulnerability that allows creation of the required file under /data. MediaTek Embedded Multimedia Card (eMMC) Contains a command injection vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. A security vulnerability exists in the MediaTek Embedded Multimedia Card (eMMC) subsystem. The following products and versions are affected: MT65xx devices; MT66xx devices; MT8163 SoC devices
