Upgrade codeception/codeception to version 4.1.22, 3.1.3 or higher.
Overview
codeception/codeception is a Full-stack testing PHP framework.
Affected versions of this package are vulnerable to Deserialization of Untrusted Data. The RunProcess class can be leveraged as a gadget to run arbitrary commands on a system that is deserializing user input without validation.
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.
