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 a broadcast receiver app component named com.suntek.mway.rcs.app.test.TestReceiver 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 broadcast receiver app component named com.rcs.gsma.na.test.TestReceiver allow any app co-located on the device to programmatically send text messages where the number and body of the text message is controlled by the attacker due to an exported broadcast receiver app component. This app cannot be disabled by the user and the attack can be performed by a zero-permission app. A separate vulnerability in the app allows a zero-permission app to programmatically delete text messages, so the sent text messages can be removed to not alert the user.

CISA SSVC: Track at low or medium mission impact; Track or Attend at high (mission-essential systems).
Action: No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
