Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Ground Station 是一款基于浏览器的卫星跟踪、软件无线电（SDR）接收、硬件控制以及遥测解码软件套件。在版本 0.4.13 之前，存在以下安全漏洞： 1. 未经认证的远程路径遍历与任意文件写入漏洞 未经身份验证的 Socket.IO 命令会将攻击者控制的 参数从 传递至 。在此处， 函数允许使用绝对路径或父目录遍历（如 ），从而导致攻击者能够将经过 base64 解码后的字节内容写入到 目录之外的任意位置。 2. 日志配置反序列化远程代码执行（RCE）漏洞 攻击者可利用上述任意文件写入漏洞，在目标系统中

Vulnerability Title
Ground Station: Unauthenticated arbitrary file write (path traversal) in save-waterfall-snapshot leads to remote code execution
Source: CVE Program / CVE List V5
Vulnerability Description
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.
