Description
The Coolpad Defiant device with a build fingerprint of Coolpad/cp3632a/cp3632a:7.1.1/NMF26F/099480857:user/release-keys, the ZTE ZMAX Pro with a build fingerprint of ZTE/P895T20/urd:6.0.1/MMB29M/20170418.114928:user/release-keys, and the T-Mobile Revvl Plus with a build fingerprint of Coolpad/alchemy/alchemy:7.1.1/143.14.171129.3701A-TMO/buildf_nj_02-206:user/release-keys all contain a vulnerable, pre-installed Rich Communication Services (RCS) app. These devices contain an that app has a package name of com.suntek.mway.rcs.app.service (versionCode=1, versionName=RCS_sdk_M_native_20161008_01; versionCode=1, versionName=RCS_sdk_M_native_20170406_01) with an exported content provider named com.suntek.mway.rcs.app.service.provider.message.MessageProvider and a refactored version of the app with a package name of com.rcs.gsma.na.sdk (versionCode=1, versionName=RCS_SDK_20170804_01) with a content provider named com.rcs.gsma.na.provider.message.MessageProvider allow any app co-located on the device to read, write, insert, and modify the user's text messages. This is enabled by an exported content provider app component that serves as a wrapper to the official content provider that contains the user's text messages. This app cannot be disabled by the user and the attack can be performed by a zero-permission app.
