RULE（RULE ID：339671）

Rule General Information
Release Date: 2025-12-02
Rule Name: XStream Deserialization Vulnerability (CVE-2021-39152)
Severity:
CVE ID:
Rule Protection Details
Description: XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream with a Java runtime version 14 to 8. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.
Impact: An attacker can carefully construct malicious serialized data and pass it to the application, and execute the malicious code constructed by the attacker when the application deserializes the object.
Affected OS: Windows, Linux, Others
