Lifecycle Timeline
4Description
A vulnerability was found in OpenBMB XAgent 1.0.0. This impacts the function check_user of the file XAgentServer/application/websockets/share.py of the component ShareServer WebSocket Endpoint. Performing a manipulation of the argument interaction_id results in missing authentication. Remote exploitation of the attack is possible. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
Analysis
OpenBMB XAgent 1.0.0 ShareServer WebSocket endpoint allows remote authentication bypass through manipulation of the interaction_id parameter in the check_user function, enabling unauthenticated attackers to access protected resources with low confidentiality, integrity, and availability impact. Publicly available exploit code exists, the vendor was contacted but did not respond, and active exploitation remains possible.
