CVE-2024-46983 Open this link in a new tabHow to fix?
Upgrade com.alipay.sofa:hessian to version 3.5.5 or higher.
Overview
com.alipay.sofa:hessian is a binary serialization protocol.
Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the blacklist protection mechanism. An attacker can execute arbitrary code by exploiting a gadget chain that bypasses the blacklist restrictions.
Note: This is only exploitable if the environment relies solely on JDK without additional third-party components.
Workaround
This vulnerability can be mitigated by maintaining a blacklist manually in the directory external/serialize.blacklist.
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.
