Dreame Technology iOS and Android Mobile Applications

Dreame Technology iOS and Android mobile applications (Dreamehome and MOVAhome) contain an SSL/TLS certificate validation vulnerability (CWE-295) that could allow an attacker with network access to intercept and read encrypted communications. The vulnerability affects Dreamehome iOS ≤2.3.4, Dreamehome Android ≤2.1.8.8, and MOVAhome iOS ≤1.2.3. Vendor has not responded to disclosure requests and no patch is available.

Dreame Technology did not respond to CISA's request for coordination. Contact Dreame Technology directly for more information. Note that MOVA is a subsidiary of Dreame Technology. CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as: Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the Internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time. This vulnerability is not exploitable remotely.
