CVE-2026-53451
CriticalCVSS 9.8Summary
Ground Station before version 0.4.13 contains a vulnerability in the unauthenticated save-waterfall-snapshot Socket.IO command. An attacker can control the snapshotName input, allowing file writes outside the data directory via path traversal. It is possible to write a YAML logging configuration file that, during service restart, executes arbitrary code (RCE) with service privileges.
Risk Assessment
An attacker can execute arbitrary code on the server with service privileges, potentially leading to full system compromise, persistent crash loop, or data theft.
Recommendation
Update Ground Station to version 0.4.13 or later. Restrict access to the service and monitor logs for unusual operations.
Original NVD description (English source)
Ground Station is a browser-based suite for satellite tracking, SDR reception, hardware control, and telemetry decoding. Prior to version 0.4.13, the unauthenticated save-waterfall-snapshot Socket.IO command passes attacker-controlled snapshotName input from backend/handlers/entities/sdr.py to backend/server/snapshots.py, where os.path.join permits an absolute path or parent-directory traversal and writes attacker-controlled base64-decoded bytes outside backend/data/snapshots. An attacker can write a logging YAML file containing a logging.config.dictConfig callable factory, use the unauthenticated update-app-config operation to set log_config to that file, and invoke restart_service. During restart, backend/common/logger.py passes the YAML through resolve_log_config_path(), yaml.safe_load(), and logging.config.dictConfig(), which executes the factory with service privileges and can also cause a persistent crash loop. This issue is fixed in version 0.4.13.
