Security readout for executives and security teams
Plain-English summary
Microsoft UFO versions before 3.0.8 can expose control of an ADB-connected Android device without requiring authentication. A network attacker reaching the affected services could view screenshots and device information, launch applications, enter text, and perform touch or key actions. This creates substantial confidentiality and integrity risk for connected devices.
Executive priority
Prioritize immediate remediation wherever affected services can be reached beyond a tightly controlled host or network. The weakness enables remote viewing and manipulation of connected Android devices without credentials. Isolate exposed services while teams upgrade, then review potentially reachable devices for sensitive screen content, applications, accounts, and unauthorized state changes.
Technical view
The mobile data-collection and action servers expose Streamable HTTP MCP services on TCP ports 8020 and 8021 without authentication. An unauthenticated network attacker can invoke screenshot, UI inspection, navigation, input, application-launch, and control functions against an ADB-connected Android device. The issue is classified as CWE-306 and CWE-862 and is fixed in UFO 3.0.8.
Likely exposure
Exposure requires Microsoft UFO earlier than 3.0.8, an affected mobile MCP server running, an ADB-connected Android device, and attacker network access to port 8020 or 8021. Internet-facing, shared-network, laboratory, CI, or automation environments may carry greater risk. The supplied sources do not quantify deployed exposure.
Exploitation context
The CVSS 3.1 score is 9.4, reflecting network access, low complexity, no privileges, and no user interaction. The supplied record does not identify confirmed exploitation, and the CVE is not listed as KEV in the provided bundle. Treat the vulnerability as readily actionable but do not claim active exploitation.
Researcher notes
The vulnerable functions are create_mobile_data_collection_server and create_mobile_action_server in ufo/client/mcp/http_servers/mobile_mcp_server.py. Impact includes screen and UI-tree disclosure plus device-state modification through exposed MCP capabilities. The provided sources establish the vulnerable versions and fix, but provide no evidence of exploitation prevalence or confirmed attacks.
Mitigation direction
- Upgrade Microsoft UFO to version 3.0.8 or later.
- Until upgraded, prevent untrusted network access to TCP ports 8020 and 8021.
- Stop affected mobile MCP services when they are not required.
- Restrict ADB-connected devices and review vendor guidance for additional safeguards.
Validation and detection
- Inventory Microsoft UFO installations and confirm their installed versions.
- Identify hosts running the mobile data-collection or action server functions.
- Verify whether TCP ports 8020 or 8021 are reachable from untrusted networks.
- Confirm connected Android devices and assess data or applications potentially exposed.
- After upgrading, verify version 3.0.8 or later and retest network exposure.
