CyberRota Analysis
AI-GeneratedMeshCentral 1.1.21 is vulnerable to a cross-site WebSocket hijacking protection bypass, allowing unauthenticated remote attackers to exploit an unconditional early return in the CheckWebServerOriginName() function when self-signed certificates are used. This flaw enables attackers to establish cross-origin WebSocket connections, exfiltrate session keys, and forge session tokens, granting them full remote control over all devices managed by the affected MeshCentral instance. Organizations utilizing MeshCentral should prioritize patching this vulnerability to safeguard against potential unauthorized access and control over their managed devices.

Original NVD Description
MeshCentral 1.1.21 contains a cross-site WebSocket hijacking protection bypass vulnerability that allows unauthenticated remote attackers to hijack authenticated administrator sessions by exploiting an unconditional early return in the CheckWebServerOriginName() function within webserver.js when self-signed certificates are in use. Attackers can open cross-origin WebSocket connections to any of the twelve WebSocket endpoints, send crafted action commands to exfiltrate the server sessionKey used to sign session cookies, forge session tokens as arbitrary users, and gain full remote control of all managed devices governed by the MeshCentral instance.
