AI-suggested

1. Restrict which applications can invoke intents on Wear OS devices by enforcing strict app permissions and intent filters, minimizing exposure to malicious apps capable of triggering ACTION_SENDTO intents. 2. Monitor device logs and messaging activity for unusual or unauthorized message sending patterns, enabling early detection of exploitation attempts. 3. Educate users about the risks of installing untrusted applications or granting excessive permissions that could facilitate intent invocation by attackers. 4. Implement endpoint protection solutions that can detect anomalous intent invocations or suspicious inter-process communications on Wear OS devices. 5. Apply security updates and patches promptly once Google releases a fix for this vulnerability. 6. Consider disabling or limiting the use of Google Messages as the default SMS/MMS/RCS app on Wear OS devices in high-risk environments until the vulnerability is addressed. 7. Use mobile device management (MDM) solutions to enforce security policies and restrict app installations and configurations on Wear OS devices within the organization. 8. For critical communications, use alternative secure messaging platforms that do not rely on vulnerable intent handling mechanisms.

Description

On Wear OS devices, when Google Messages is configured as the default SMS/MMS/RCS application, the handling of ACTION_SENDTO intents utilizing the sms:, smsto:, mms:, and mmsto: Uniform Resource Identifier (URI) schemes is incorrectly implemented. Due to this misconfiguration, an attacker capable of invoking an Android intent can exploit this vulnerability to send messages on the user’s behalf to arbitrary receivers without requiring any further user interaction or specific permissions. This allows for the silent and unauthorized transmission of messages from a compromised Wear OS device.
