A flaw was found in Eclipse Che che-machine-exec. This vulnerability allows unauthenticated remote arbitrary command execution and secret exfiltration (SSH keys, tokens, etc.) from other users' Developer Workspace containers, via an unauthenticated JSON-RPC / websocket API exposed on TCP port 3333.
AnalysisAI
Eclipse Che che-machine-exec exposes an unauthenticated JSON-RPC/WebSocket API on port 3333 that allows remote command execution and secret exfiltration from other users' developer workspace containers.
Technical ContextAI
The che-machine-exec component exposes a JSON-RPC API over WebSocket on TCP 3333 without authentication (CWE-306). An attacker can execute commands in any user's workspace container, accessing SSH keys, tokens, and source code.
Affected ProductsAI
Eclipse Che (che-machine-exec component)
RemediationAI
Restrict port 3333 access. Apply Eclipse Che security updates. Audit workspace access logs.
