Remote Code Execution by Pickle Deserialization via FlightServer in pyquokka

pyquokka is a framework for making data lakes work for time series. In versions 0.3.1 and prior, the FlightServer class directly uses pickle.loads() to deserialize action bodies received from Flight clients without any sanitization or validation in the do_action() method. The vulnerable code is located in pyquokka/flight.py at line 283 where arbitrary data from Flight clients is directly passed to pickle.loads(). When FlightServer is configured to listen on 0.0.0.0, this allows attackers across the entire network to perform arbitrary remote code execution by sending malicious pickled payloads through the set_configs action. Additional vulnerability points exist in the cache_garbage_collect, do_put, and do_get functions where pickle.loads is used to deserialize untrusted remote data.

可信数据的反序列化

quokka 代码问题漏洞

Quokka是开源的一个用 Python 编写的内容管理框架。 quokka 0.3.1及之前版本存在代码问题漏洞，该漏洞源于FlightServer类在do_action方法中直接使用pickle.loads反序列化来自Flight客户端的操作数据，可能导致远程代码执行。
