Deserialization of Untrusted Data
CVE-2023-38647
Summary
An attacker can use SnakeYAML to deserialize "java.net.URLClassLoader" and make it load a JAR from a specified URL and then deserialize "javax.script.ScriptEngineManager" to load code using that ClassLoader. This unbounded deserialization can likely lead to remote code execution. The code can be run in Helix REST start and Workflow creation. This issue affects org.apache.helix:helix-core and org.apache.helix:helix-rest versions prior to 1.3.0.

CWE-502 - Deserialization of Untrusted Data
Deserialization of untrusted data vulnerabilities enable an attacker to replace or manipulate a serialized object, replacing it with malicious data. When the object is deserialized at the victim's end the malicious data is able to compromise the victim’s system. The exploit can be devastating, its impact may range from privilege escalation, broken access control, or denial of service attacks to allowing unauthorized access to the application's internal code and logic which can compromise the entire system.
