CVE-2026-73296: CWE-306: Missing Authentication for Critical Function in microsoft UFO
Microsoft UFO open-source framework for intelligent automation across devices and platforms. Prior to 3.0.8, create_mobile_data_collection_server and create_mobile_action_server in ufo/client/mcp/http_servers/mobile_mcp_server.py exposed Streamable HTTP MCP services on TCP ports 8020 and 8021 without authentication, allowing an unauthenticated remote attacker to invoke capture_screenshot, get_ui_tree, tap, swipe, type_text, launch_app, press_key, and click_control against an ADB-connected Android device, disclose screen and device data, and modify device state. This issue is fixed in version 3.0.8.
AI Analysis
Technical Summary
Microsoft UFO is an open-source framework for intelligent automation across devices and platforms. In versions before 3.0.8, the functions create_mobile_data_collection_server and create_mobile_action_server in the mobile_mcp_server.py module expose Streamable HTTP MCP services on TCP ports 8020 and 8021 without authentication. This allows unauthenticated remote attackers to invoke multiple critical functions such as capture_screenshot, get_ui_tree, tap, swipe, type_text, launch_app, press_key, and click_control on an Android device connected via ADB. The flaw corresponds to CWE-306 (Missing Authentication for Critical Function) and CWE-862 (Missing Authorization). The issue is resolved in version 3.0.8.
Potential Impact
An unauthenticated remote attacker can fully control an ADB-connected Android device via exposed HTTP services, leading to high confidentiality and integrity impact by disclosing screen and device data and modifying device state. Availability impact is low. The CVSS 3.1 score is 9.4 (critical).
Mitigation Recommendations
Upgrade Microsoft UFO to version 3.0.8 or later, where this authentication issue is fixed. No other mitigation is indicated by the vendor advisory. Patch status is not explicitly confirmed in the advisory, but the fix is stated to be in 3.0.8.
